I think one on hearing would also be useful. Is it really inevitable that we lose our hearing when we age? Is it a sign of dementia? Why are those with poor hearing more at risk of dementia?
Yes, I want to see this as well. Also tips to keep your hearing as good as possible for as long as possible
No being able to hear is bad for your brain. Also, people that don't hear well tend to isolate themself from others. This being "cut off" from the world is a huge risk factor to develop dementia!
I hear You, brother! Also appreciate how a channel named Little Voice is recommending something about hearing.
I wonder if diet is connected with hearing loss (besides trauma) as it is with dementia. Because genetics can be dormant or triggered according to one’s diet more or less
That's simple. Loud noises of any sort can damage hearing.
To protect hearing don't listen to music too loud, particularly on earphones/earbuds,and if operating loud machinery use ear protecters
I am glad to hear that blue light isn't actually damaging. My full time job is working on the computer,but I never opted to get the blue light filter which would always shock my optometrist. But the truth is, I need to see colours correctly with my job and the filter interferes with that too much. I was always worried I was choosing to ruin my eyes to be able to pay my bills 😅
I don't know if it's some Placebo effect but without that blue light filter my eye feels drier than usual
Blue light by itself is not dangerous, but the narrow band blue light peak emitted by most LED backlit screens is. It's high intensity of light concentrated in very narrow spectrum. If it was spread out over wider frequency band (like natural light sources), then it wouldn't have such high toxicity for the tissue.
they didn't say blue light isn't damaging to your eyesight or health, they just said there is no reasearch can claim such thing as to right now meaning there is no reaserch who shows blue light is damaging or not dammging to the eyesight therefore blue light can still be damaging and you simpley don't know it yet.
@@lala-bp3wh bruh they just said our eyes have protection against blue light. She even mentioned specifically that we have "Lutein and Zeaxanthin" in our eyes that protects us from blue light. The only reason why it affects our eyes is when we use gadgets before sleep causing insomnia or when we forgot to blink.
@@lala-bp3wh plus if it were even slightly true then we would have a pandemic of blindness.
Regardless of 'damaging' eyes, when I got blue light filter glasses I stopped experiencing eye strain/twitching. My eyes would always start twitching around 2 o'clock at work. I got blue light filters over a year ago and haven't had the problem since. I won't be switching back just to save a few bucks.
Well, they do say blue light filters reduce light sensitivity and glare and make you feel more comfortable when you work (2:10)
Brk u heard intro? This is fake. They said contact lense cant het stuck behind eye
every heard of a placebo 🤓
@@pilkzzz Yeah, as in you can place 'ez bollz in ya mouth. (It's a stretch but I think it works 🤔)
they just say there is no proof that it does damage your eyes, what they say blue light does affect you differently like can give you insomina but those bluefilter just helps in making you feel comfortable and help with light sensitivity
If the original study about blue light damaging your eyes was done with cervical cancer cells, does that mean blue light could potentially treat cervical cancer? If so I think that could be really cool.
that’s what i was thinking.
I also thought the same
Blue light can change dna in a cell and changed dna if mutated can cause cancer so it's hit or trail it not always gona kill
It's proably inferior to the current cancer treatment options out there. From what I gather what they mean is that blue light can kill ALL cells if they're not protected by those specific pigments in our eyes. This is basically what the current radiation/x-ray therapy methods already do, but at a higher efficiency.
The problem with that is that visible blue light can't really penetrate our skin and get to the cancer. If it could, you'd be able to see your screen through your hand. That's why we use other types of radiation that can actually penetrate the body and attack the cancer cells
Contacts can't got lost behind the eye, but they can get lost at the top. Happened to me when I first was getting them in 7th grade. The first time one somehow got stuck past my eye lid and when I was putting on the replacement, it fell out and the doc was like I've never seen that before. The floaters one is the most scary to me because my current eye doctor told me that the vein to my eye is pretty thin and said my eye could fall out if it gets thin enough, so if I start to see more and more floaters, to contact her ASAP.
this happened to me just today! the lens got lost at the top lmao
Your eye won’t fall out. If you see floaters or flashes that COULD be a sign of a retinal detachment which could lead to blindness
The problem is that the retina, the patch of nerve cells at the back of the inside of the eye, which react to light and without which we can't see,needs a good blood supply.
If something interrupts that blood supply, such as damage to the capillaries (very small blood vessels)that carry blood to the retina,then those cells can be damaged.
Once the retina is damaged,there is nothing that can be done to fix it.
BUT, there are things that can be done to improve the blood supply before that happens/re attach your retina if it detaches ,such as laser surgery.
If you have bad floaters,this can mean there is damage to the capillaries, though generally it doesn't. But an eye check is a good idea .
If you have bad floaters,then suddenly loose an area of sight in your eye,like a dark spot that doesn't move,you need to seek treatment straight away,as you DO have damage to the capillaries/a detached retina
The sooner you get treatment, the more likely it is that your retina/its blood supply can be repaired and your sight will be fine
Never take chances with your sight
happened to me too😭😭😭freaked out while trying to find my contact bc i thought i dropped it but it was slid to the right of my eye
The top, sides, and bottom. Basically the contact won't go all the way behind the eye, but it can get stuck anywhere around the edges as far back as your conjunctiva connects. It happens to me fairly often (as in a few times a year), usually when my eyes are really dry and the contact catches on my eye lid and rolls up.
I was literally "prescribed" eye exercises by my ophthalmologist. He said my problem wasn't myopia but rather exhaustion of my eye muscles, which was later confirmed by a dysautonomia specialist. I'm wondering if maybe there are cases where eye exercises or eye rests do help, or whether my eye doctor was simply misinformed.
Following
They stated that eye exercises don't help with myopia and other vision-impairing conditions; so if a professional told you that it wasn't myopia and rather a specific problem with your eye muscles than eye exercises can probably help somewhat since it has to do with your muscles.
What they mean is that eye exercises won't help you with said conditions, or magically improve your vision from where it is now. It can help with eye strain.
@@blasianking4827 Thank you! That makes sense. Sometimes these videos can lack nuance which can be confusing.
Losing weight & fasting improved by vision & reduced myopia.
From my experience, when I checked my myopia in the morning and evening, the numbers are different. It is very recommended to check your eyes early of the day, otherwise your eyes are tired during eye check in the evening and lead to inaccurate numbers.
I can't believe none of my eye doctors told me that Polarized lenses don't necessarily block UV.
I've lived in high UV places most of my life and have worked outdoors. I was so careful to get polarized lenses because I'd been told by family members those were the most effective against UV.
Only now am I learning I could've been better protecting my eyes this whole time!
sunglasses work better than polarized
It may not be damaging, but as someone who spends 60-80 hours a week in front of screens, I had noticably reduced eye fatigue, and general eye strain, when I started using glasses with a filter. The filter isn't even really noticeable on day-to-day things either, it just takes the edge off and makes a huge difference for me.
My friend kept seeing floaters and when she got herself checked, it turned out it was blood and found out she has a growth in her brain. Always get yourself checked when something feels off.
In other cases.. if you keep seeing one, two floaters or more.. it could be the early sign of retinal detachment.. which is could lead to permanent blindness if not do any early treatment.. do check to your ophthalmologist.. not optometrist
@@soupricemf1260 only if they suddenly appear. Floaters are normal due to proteins and are usually not an issue.
@@SmallSpoonBrigade not the sudden appear.. im talking about the permanent floaters/ same shape and position of the floaters in one or two eyes
@@soupricemf1260 what about floaters in three eyes? jk
@@GunwantBhambra u are the devil then
One thing I learned from experience is that the glasses won't make your vision worse, BUT since I got my glasses way too late (in my 20s) I had already gotten used to not seeing right(shortsighted + astigmatism). Then as I started to wear them every waking hour, I got used to seeing perfectly fine. So now, when I take them off, I trip and run into stuff more often than I did before, but that is not because I see worse but because I am no longer compensating by being exceptionally careful. I think that often causes people to mistakenly believe their vision got worse.
How do you know glasses won't make your vision worse? Do you know excessive near work leads to myopia?
Aren't you familiar with primate studies 30 years where they had minus lenses put in front of their eyes, and they developed myopia.
Hard to fight the general ignorant public that doesn't want to hear anything/do his own research about this subject.
1.Take 100 7 year old kids who are illiterate and check their vision 2-3 years after
2.Take 100 7 year old kids who do 10hrs reading at 30cm and check their vision 2-3 years after
3.Take 100 7 year old kids who are always outside but are put with -3.00D minus lenses and check their naked vision 2-3 years after.
scenario 2+3 = Myopia, and this is proven by science.
@@DoubleOpposite You seem to be completely unable to de-tangle how causal relationships work. But it's okay. Watch the video again, maybe you'll understand it this time around, although I highly doubt that.
@@diablo4093 You're ignorant to science, and its fine by me
In science, near work and minus lenses cause myopia
In medical myth however, no
@@DoubleOpposite You do realise that if people started off with perfect vision and wore the lenses long term, their eyes would actually adjust to lenses and end up inducing myopia? The monkey and the kids wearing the minus lenses scenarios are not really proving that nearwork causes myopia because the lenses are already a huge factor, so perhaps reference more examples where they only have nearwork activities involved in the experiment to better support your argument.
If something hits your eye but you’re eye is closed will not end up getting low vision. I rinsed something off my eye lids in the shower today and I had water fall on my face for five minutes and my mom told me that water from a shower falling on your eyes could cause permeant damage and oh dear I had shower water fall on my face for five minutes but my eyes were closed the whole time I did it. If someone rinses his or her face under shower water for five minutes with shower water with his or her eyes closed would the water falling on your face still damage the person’s eyes and cause the person to get low vision even though the person’s eyes were shut while the water was falling on the person’s face?
Commenting to boost the algorithm. I'm a COA in Arizona and more patients need to see this video. Very well done, very comprehensive, and of course very accurate. Thank you to the production team and the doctors.
enjoy your profits off of glasses sales. I'm not sure how you people sleep at night. I guess I would sleep well if I made that much money'
@daniyal chaudhry Nice try with the sarcasm deceiver. Eye exercises work and the only proof that they don't is the fact that optometrists refuse to study them because it would lose them tons of sales.
@@rhythimrt9970 LMFAO!
@@rhythimrt9970eye exercises train the eye muscles how tf would it change the shape of ur eyeball
I can understand the "glasses makes your vision worse" one. One thing I've noticed that people don't think about is that when you take off your glasses, your vision IS worse than usual for a short time. Just like with light level adjustments it takes a little time for your eyes to adjust to not having the glasses again. After a few minutes you'll notice your glasses-less vision is just as good (or lets be real, probably as bad) as usual.
yeahh its just adjustment to the new normal
It is the stupidest thing but I often find myself becoming a little frustrated when it's shower time because it means removing my glasses and now I can't see very well 😂. If I'm in bed on my phone, I don't mind not wearing them but once I leave my room, or I'm up moving around, I really need them.
I wonder if people who have contacts wear them in the shower as well or would that cause steam on the lenses...
For me it was more permanent, I had to stop wearing glasses and my "normal" vision restored only after a few weeks.
Thanks for debunking the blue light myth. I was tired of seeing the green tint so when I got a new pair of lenses I purposefully opted for plain glasses and that helped me to save Rs300 (that's like 4 dollars). My Doctor said I should keep using blue light glasses but I just refused and now thanks to you I am more than sure that I made the right choice.
Same, the shop I went to kept pestering me to "upgrade" the blue light lens but I feel so sleepy using them so I went for the normal version and saved $100!
Seems like every shop wants to push for those blue light filters, they probably get paid commission for it.
It's not a myth. These two medical doctors, like most medical doctors, wildly unscientific, are clueless about the basic science and cannot even infer a truly logical consequence of the hypothesis that they wish to refute [01:16]. The conclusion that blue light damages eyes owes to decades of research.
One could question much of the data's clinical relevance to freeliving humans. But these medical doctors spout nonsense by reducing it all to a myth due to media report of a 2018 study on cells not even retinal. And refuting the hypothesis by alleging that it entails a "pandemic of blindness" is sheer inanity.

I gotta say if your family has cases of macular degeneration I would still use blue light Filters. but otherwise I don't see any arguments for them and I only sell them if a patient/ customer wants them.
and they can enhance contrast vision so if you have problems there also good investment.

I have convergence insufficiency and once a week I had to do some really cool 3D exercises as a kid. The ophthalmologist put red/blue glasses on me and I had to try to align some figures at different depths.
I had LASIK and after 10 years my eyesight was so near-sighted I had to get glasses again. Yet my mother-in-law and husband had LASIK before me, it's been about 20 years since their surgeries, and they can still see perfectly. So you never know how it'll go.
Can't you just get it again?
@@neo-filthyfrank1347 not really. LASIK literally shoots your eyes with lasers. boring into them.
@@wetswordfighter Children with rudimentary understanding of subjects should not be commenting acting like they know anything.
@@neo-filthyfrank1347 toxic much... and who says i'm a child? just because i play video-games? Bullshit.
@@neo-filthyfrank1347 also you're wrong anyways because every source is telling me that LASIK uses special cutting lasers to change the shape of your cornea, which is basically boring small holes into them. which is not able to be fixed, as your eyes are well, your eyes. Maybe you should do some research.
I think people think the only reason blue light is damaging is because it can so-called "cause eye deterioration". Yes and no. Blue light doesn't directly affect your eyes, but because your eyes don't really close when you're playing a game or concentrating on a video, it can cause eye strain and dryness, which then those symptoms lead to blurriness.
should I keep blinking in between?
@@lucidgames2580 yeah
thats what i do and i also look away from the screen like every 20 - 30 mins for about 10 seconds and then i continue playing
It's no and no. Blue light isnt harmful, prolonged screen time w/o rest is
I think i have this case. Usually i play games straight 9 hours if i'm not busy at school or even 12 hours straight. Now my eyes is soooo blurry😢. Do you guys thing LASIK will help my eyes?😢
Actually, blue light irradiation of lipofuscin results in the production of free radicals. Retinal cells accumulate lipofuscin over time, which is why blue light is especially hazardous to older individuals, but not so much to younger individuals.
While it certainly is unusual, it's not impossible to sneeze with your eyes open. I was recently diagnosed with a condition called Bell's Palsy, where one half of my face experienced muscles weakness. One of the symptoms included a weakened eyelid and blink reflex, so when I sneezed, I was fully able to see out of that eye every time. It was rather uncomfortable, and luckily healed up soon after, but because of that I can say that I have sneezed with one eye open.
I'm sorry, I'm sure it was a very uncomfortable experience, but the mental image of this is pretty funny. I'm glad you're doing better now.
Exactly, when I heard as a kid that one couldn't sneeze with their eyes open, I literally held my eyelids while I sneezed just to prove I could, and I still have both eyes
“One eye open when I’m sleeping on eeeeye”
It's hard when you're driving and you're about to sneeze because you have to keep focused on the road, just closing your eyes for a second can be frightening.
one eye open when I'm sneezing
I've been wearing contact lenses since 1986, I've never had an eye infection in all those years, never had a problem wearing them, can put them in and out without a mirror, I hate glasses. My husband is 86 and has 20/20 vision but has glaucoma, had one cataract done but can't have other one done due to damage from glaucoma. Thanks for this girls!
When I have lost a contact into the top or side of the eye, I have been able to move it forward by gently rubbing the top of my closed eye. The lens is usually folded, but I can then extract it.
Adding blue light filters to my glasses was a game changer once I had to use my computer more for telehealth with my clients.
I wish you had discussed monovision with contacts & about bifocal contacts.
One thing to note (and this is explained in the video but most people seemed to not actually watch it, just read the thumbnail): while blue light is not harmful to your eyes, it can still affect your circadian rhythm. Blue light sends the signal to our brain that it's daytime, and that we should be more alert. Setting a blue light filter on your phone, computer, etc., using blue light filtering glasses, or simply limiting nighttime screen use can all be beneficial to your sleep, and thus to your health.
They wont answer you now.
I don't think this is scientifically proven either. I saw studies that didn't find correlation between blue light and sleep. What did seem to have a correlation is how engaged you are when you're using your phone/computer before bed. For example if you're reading a very exciting book before bed it doesn't matter if it's on a phone screen with blue light or on a piece of paper - you're going to have trouble falling asleep. I don't have a link, but I found it by just googling.
When I 1st started wearing contacts I wore gas-permiable contacts. My sophomore year I got poked in the eye and felt the lense go behind my eyelid. I went to 2 different ophthalmologists and could not find anything even though I could feel something there for 2 years. 12 years later I went for a routine ophthalmologists visit and when examining my eye lid. I blinked and my contact lens popped out with a whole bunch of skin cells growing on top and below it.
That’s horrifying! I still wear gas permeable contacts.
spooky
That’s the most horrible physical reaction I’ve ever got from a story
Wow. That sounds insane! GP lenses are hard, so its crazy to think that it stayed in your eye for that long without causing you severe discomfort.
I somehow want to see this
Thank you ladies, so calm and pedagogical! I would feel very safe as a patient.
I have convergence insufficiency and I did vision therapy for about a year. It definitely improved my vision. However, I do need glasses because my eyes get strained very easily. The glasses just help my eyes relax and give them a break from focusing so hard.
Cbd helps eyes from straining
Lasik: I had LASIK twice. I was 5/200 prior to Lasik. Went to 20/15, back to 10/20, before the revision. My eyes have settled to a very mild near-sighted again. I hover around 15/20 or -0.75 in both eyes now. I would love not needing glasses, but at least now I'm not legally blind if I forget them at home. The procedure did fix an astigmatism that was developing!
What does 5/200 mean?
@@roshnigupta9914 I believe 5/200 means that the smallest thing he can see from 5 feet away, a normal person could see the same thing from 200 feet away. So imagine a huge sign on the streets, this person would have to be 5 feet away to see the huge sign that a normal person can see from across the street.
@@TARS.. ok so what would that be in normal sign convention?
@@roshnigupta9914 20/800. Lasik is a terrible idea. You're fundamentally damaging the structure of already delicate tissues. They'll fail progressively over time and studies are just starting to show this.
@@TARS.. my both eyes are around -4.25-4.5 the last time I checked. Though I'm not blind, I can survive in the house without the glasses and can perform the daily routine, there's no way I can last a few hours outside as I can't see shit.
Not just in eyes, but in skin and hair too. Pigment takes a little bit to come in. I hear a lot of silly stories from first time parents thinking that a child isn't theirs because the pigment hasn't come in. I'm half native, half white. Everyone in my family was born blonde and blue eyed like my mother and then half of us kids had our eyes and skin darken, and all of us had our hair darken to varying shades of brown and black like my father.
My mother's eyes also changed from blue to green when she was 43 while undergoing chemotherapy. They've been green ever since. Not sure why that is.
You mother had or has yellow skin or something? Because if she has a condition that affects liver and the skin became little yellow that can be a thing, because yellow with blue give you green right ? I don't know just talking, don't know how silly i am right now in this commentary but... or she eats lots of carrot? Rs that's turn your skin yellow too

@@atheistyoda8915 • rookie number, i’m 7777 years old
I think you meant 40 lol
Such a wonderful video, the doctors, the informative content, the music, even the length of the video! i like all of it.
Thank you for mentioning the blue light myth! I constantly get asked about buying blue-light blocking for my glasses, and I always say no, although for a different reason than most people. I have narcolepsy, a disorder that severs the connection between my circadian rhythm and the rest of my brain and causes neurotransmitter imbalances as a result.
In a healthy brain, a neurotransmitter called orexin directs when other wakefulness promoting neurotransmitters are released. As just one example, dopamine levels spike in the morning, giving you the urge to get out of bed.
My orexin-producing neutrons are mostly or completely gone as of an autoimmune attack that happened when I was 14. With no orexin to direct the brain, dopamine, norepinephrine, histamine, serotonin, GABA, and other important neurotransmitters don't get released in the normal organized way.
In the same way that a diabetic has to do the job of their pancreas, I have to do the same for my hypothalamus through medications and lifestyle changes. Blue light promotes wakefulness, so I use it during the day to remind my brain that it's wakefulness time. At night, my lights switch to yellow, which helps my brain settle down for sleep. It’s not a life-changing strategy by any means, and I definitely need several medications as well, but it does help!
Interesting! I have narcolepsy too. Unfortunately, blue light doesn't do a good job at keeping me awake. I know this because i tried gaming during the pandemic but i wasn't taking enough medication at the time and i couldn't even do it for 10 minutes (which resulted in losing an hour of trying to stay awake). Games on the smartphone are even worse. It think it is more exhausting because the screen is smaller.
@@sarahvandekerkhof1458 That’s fair! Even among narcoleptics, the strategies and medications that work for one person may not work for another. I should clarify that I can’t just use blue light on my phone, I have to use certain light bulbs in floor lamps to get the best effect. I have a color-changing smart bulb in my floor lamp, and I use a combo of routines on the Cync and Google Home apps to control it throughout the day. I also have a regular 60-watt equivalent LED daylight light bulb in my desk lamp lamp, since I don’t need that one to turn on/off or switch colors on it’s own.
Blue light from my phone doesn’t help much with wakefulness during the day, but I definitely need the night shift filter at night to help combat that wonderful narcolepsy insomnia 🙃 I always ended up playing ACNH until 4 AM when I was home at the beginning of the pandemic lol
I hope you both well and stay healthy. Seriously
It is not a myth. These doctors didn't give full information. There's an actual research done on it and it's been discussed via neuroscientists like Andrew Huberman.
Love this ❤️. I especially liked that you spoke about blue light glasses. While we advise patients to get them, it’s unethical to threaten them with vision loss if they don’t use them.
So true and I hate when professionals do that. I've never and will never tell px they will lose vision when recommending blue light specs, it feels unethical.
on most devices there is usually a feature somewhere in the settings where you could decrease the amount of blue light. you can even choose what time of the day you want to enable it. i use it on my phone at night before i sleep.
Refreshing to see an Ophthalmologist and Optometrist side-by-side discussing everything they know and learned about the human eye.
My parents left me under the sun as a baby, as a result my eyes were ruined. Thanks mom and dad.
@@fynkozari9271 sheesh
It was refreshing but I feel they could have found a better spoken more articulate OD… the OMD shined thru on this one
Have a well earned thumbs up! The point this became clear was when you didn't just talk about how blue light doesn't hurt your eyes, but does have other effects (e.g. difficulty sleeping).
As a truck driver I rarely wore Sun glasses. Because it's easier to just deal with the glare then cleaning my sunglasses. I think this will change after seeing this video. Also I'm way overdue to see an optometrist. Thank you.
I remember back in the early 1960s, people were saying that if you roll your eyes around and look up and down, or right and left, at extremes, it would exercise your eyes and reduce (or eliminate) the need for glasses. Even Jack LaLanne advocated eye exercises (the only time I really thought he was wrong about anything).
Thank you for sharing this valuable piece of information👍🏽appreciate it as it helps a lot
I actually had more than one cases where one of my contact lenses was folded and hiding probably where the top of my eyeball is, so not really at the far back. I felt it being loose and when blinking I lost it, assuming it had fallen somewhere in my bathroom. The first time that occurred, I thought nothing of it and just replaced it. I didn’t realize until the next day when I woke up with an irritated eye that there was something in there. Had to lift my upper eyelid, look down and do a massaging move to bring down whatever was up there. It was folded in half and tucked in there, and I could feel nothing except a very mild irritation. The following times a similar contact “loss” happened I knew exactly where to check and it was kind of a non-issue since then. Recently I had Lasik and glad I don’t have to stick anything in my eyes for the rest of my life (hopefully)
This is why I always wear glasses. Contacts are too much of a pain
Had this happen to me so many times!! Was looking to see if anyone else commented on this.
Blue light? I was checked in school and again at 18 years old during regular checkups and passed with normal color vision.
After being around welding for a dozen years I failed the color vision section of my examination. A 21 picture battery and I missed all 7 blue cards.
I work in aluminum ships etc with very reflective mirror-like walls. Even in another room facing away from the welding we get significant blue light.
The doctor giving the exam told me I was lying about passing previously because (in his words) color vision doesn't change. He didn't care to check my record.
I mention these results to all my eye doctors over the years (I am now 62) and get mixed results including "Hmm" and "I did not know that".
More than one has stated: Without a doubt, the intense blue light from welding has lowered the sensitivity of my blue cones.
Many welders over the years have been blinded by the light radiation.
While UV is blamed for burns and blisters on the eyes, welding light contains intense visible (red green and blue) light, ultraviolet, and infrared radiation.
I think it's time to update your myths. At least include exceptions and qualifiers in your language.
Fair point -- normal intensity blue light may not be damaging, but high intensity of blue light (and maybe other wavelengths too?) might cause damage.
any intense electromagnetic radiation, blue or not will be damaging to the eyes. This is nothing specific about blue light. Not even comparable to blue light in our screens - it's like comparing a pottasium isotope in a banana to a chuck of uranium lmao.
@@Nah_I_Would_Plummet Sooooo, my objection is to the "MYTH" that blue light hurts your eyes. You seem to agree that it can. I can no longer see blue as well as I should. Numerous jobs (like a pilot) require perfect color vision. My eyes are permanently damaged. GFY with that banana lmao.
It was interesting to hear about the blue light. I’ve known for a while it was a myth, so I was pleasantly surprised when I went to get my eyes tested a few days ago and my optician did not recommend it. In fact, looking on their website, I don’t think they even offer it any more. They did recommend glare reduction for my lenses, which I took, but - yeah. Some interesting myths there that I’d never heard of!
My eye doctor, when I last had my eyes checked, didn't recommend blue light filtering, but did mention it as an option as I was - at the time - going to start needing two separate prescriptions for long distance and medium distance (specifically for using the computer as my job at the time had me in front of a computer 9+ hours per day, and I was spending another 3-6 hours per day in front of my computer at home) and suggested getting yellow-tinted lenses for my computer distance glasses, basically as a combination of the tinting helping with my migraines (due to the reduced brightness, and generally being less bothered by 'warmer' light temperatures, not because of any damage from the blue light) and the blue-light reduction helping with my horrible sleeping patterns.
It is certainly good, though, that both eye doctors and more scrupulous opticians are not trying to further the myth that blue light is going to damage your eyes or cause eye strain, as opposed to simply causing some issues to your sleep schedule.
Through a large portion of my 20's I had an issue where if I didn't go outside and do routine cardio (running/walking) my eyesight would be noticeably blurry at most ranges. Going out for around 30 minutes or more and looking at things at various ranges (from the very near to the very far like distant mountains) tended to result in my vision becoming clear again. Later I started taking a specific multivitamin that also contains some "superfood" concentrates and minerals. For whatever reason I've basically preferred to be housebound for the last 3 years (starting a few months before the whole covid thing), rarely going outside, but when I have to (to put out garbage and recycling) I've noticed that instead of my vision being very blurry like it used to be, it is clear at all ranges. I suspect it had a lot to do with me being chronically malnourished when it comes to certain things in those multivitamins, but otherwise well fed.
Edit: Thought I should elaborate on a couple things. Specifically it was after a few days of not going outside that my vision would worsen. The multivitamin is a one a day kind, and not very expensive.
what is the multivitamin which one ?
@@teopeiramatikos Look for "webber naturals most complete multi". They've 4 options, Men, Women and the other two are the same for those 50+ years old.
I do supplement with other things. I had the eye benefits long before taking them but at some point I added a multi-B because I thought I might be a bit low in them. I also take vitamin-C crystals mixed with fruit juice since I think it might benefit the gums to come into direct contact with it (instead of swallowed inside a pill bypassing the gums), C-rich fruits are probably best though. Omega-3 as well, I believe Omega-6 is easy to get in the diet and the human body can manufacture enough Omega-9. I take vitamin-D drops as well since I don't get enough sun daily.
@@dimeuno thank you ill chech them out 🙏
Right, the thing about not being able to fix your eyesight is complete bs. For some kinds of shortsightedness at least. I am basically the same case as you, I started doing some exercises, like shifting focus from near to far and alike, multiple times a day. I can see my eyesight improving every few days.
@@bgdgdgdf4488 I play apex legends at the top level, competing with pro players even. If I don't do eye execs for a few months, I'll perform like trASSh. But a few days of eye exercises? back to 20/20. I even have a chart printed out to test it. You download them and use a measuring tape to space out where to stand and then boom, goodbye to optometry's "degree holding" salesmen.
So does this mean blue light can possibly be used to treat cervical cancer?
Unfortunately, you could only expose the outer layer of the tumor, and not even all of that layer. Also, the intensity of light required would generate heat and could also damage adjoining tissues.
Yes, light/laser is an available tool, but if the tumor is that readily accessible, it could be removed more completely and easily by freezing - such as a wart.
My brother is just starting treatment for prostate cancer using radiation seeds and a fine laser beam.

Some of these myths are spread by professionals though...easier targets are the blue light, which gets them a return cause a "blue light filter" option when we get new glass lens are paid with a premium price and one and the eye exercise to improve the lens and the muscles around it are everywhere on youtube, spread by actual eye doctors.

I had an eye surgery recently and feel a mayor recession on my left eye. I feel it unstable, I thought the fatigue from looking into screens with close range vision and blue light ruined my surgery (hearing the second didnt relieves me a bit). I'm going to have a consultation soon. But I would like to hear an optometrist here too.
6:12 "eye exercises" are also used for improving accommodation. Some people have isues with that so there are exercises that help the brain to relearn how to accommodate the lens.
Thank you for the part about blue light. I've been worried for a while now that, even though I have the blue light filter on my phone screen and a slight blue blocker in my glasses, my eyes were being damaged and it would be a problem later on. So thank you for easing my mind!

I was too
If you believe it’s not damaging. You need help and actually look it up.
I would still keep the filters on all day.
I used to look at a screen for hours it got my eyes dry and the far away things seemed blurry. But then I started going out more with friends and living a more healthier life. It somehow solved that issue and then i was able to look at far away things easily
Same here. It’s amazing what a change in habits will do. It’s absolutely mind boggling more doctors don’t talk about this.
Same here! I use Rose water drops to relieve it. Could you tell me in detail how you got rid of it?
I love this episode because it offers BOTH an Opthalmologist (MD) and an Optometrist (OD), both doctors but work usually in different settings. Very cool info and debunking thank you.

Only one of them is a medical doctor.
@@MrAwesomeSquad So? They are both eye doctors so your point is irrelevant
@@carrela1000 there's an ENORMOUS difference between a medical doctor and someone you see in a Walmart.
@@MrAwesomeSquad What are you even talking about? One of them is a medical doctor that specialises in eyes and the other one is a licensed eye doctor. It's literally in the name! The optometrist is a licensed doctor and completed a doctorate degree in optometry plus clinical training. The only difference is that one has an MD and the other one doesn't. She is a doctor, maybe not a medical doctor but still a doctor. Therefore, they are both eye doctors so the OP is correct. Only one of them can perform medical and surgical operations but they both treat eyes. I don't know which Walmart hires optometrists as staff and pays them as much as an optometrist earns. You may be confusing her with an optician (also not found in Walmarts either) because I hope you're not dumb enough to devalue this woman's hard work just because she doesn't have an MD and the other one does.
@@MrAwesomeSquad TIL that optometrists go to Walmart while ophthalmologist don't...
The talk about eye strain due to string at a computer screen reminded me that I had much eye string when I first changed from walking all over work sites to sitting at a computer most of the day. Oddly, web searches did not lead me to taking a break and looking at things at different distances. What I did find was that looking at five or six different "3D Magic pictures" for two or three repetitions did relax my eyes.
Since then, not just for my eyes but for every bodily and mental reason I enforce frequent breaks to get up and walk/look around.
On a different note, during the same time range, my right elbow became extremely sore. A guy showed me how to stretch the elbow using a towel across the back of neck, held in each hand. Then I stopped using a mouse and since then only use a touchpad = tiny muscles for tiny movements.
Amazing!! thank you very much for the class Docs!! Great video!! Keep it uuuuup!!
Have a history of glaucoma in the family and my pressures were elevated. Dr. gave me drops to rule out that issue and only used on one eye. Pressure dropped but not enough to warrant continuation. Turns out that my cornea is thicker than usual (my brother has the same) so the Dr. took me off the drops. If I recall correctly, those drops may cause eyelashes to grow more but also, over time, could have made my blue eyes become darker - which isn't a bad thing, just not a desired outcome as I and others rather fancy their color.
The drops that make your eye lashes grow are prostaglandins so the drugs such as bimatoprost, latanoprost, travoprost and tafluprost. Usually they are used in both eyes since they can darken the iris. The iris is less likely to change in colour if your eyes are fully blue with no specs if green and brown. There are no changes in colour once you stop using the drug however.
These are two fantastic doctors well respected in the eye space. Nice video!!! The enthusiasm and passion is second to none!
I just love listening to these doctors speak the truth behind myths 💯💕
I had to watch this video minimized into a smaller window because it is uncomfortable to watch a pixelated 1080p visual, but thanks for the good slides and animation which make it easier to understand many things.
I really love these scientific and educational videos. Channels like Wired, Insider, etc are making learning fun again!
ChatGPT? Is that you?
I cured my lazy eye with eye exercises! At 21 years old as well… I was wearing eye patches and glasses since I was 4. Sometimes when I am tired I wear contact lenses. If I wear them too long I notice my eyes are weaker and turn in again. I then do a few eye exercises and the eye stops turning in.
I was really determined though haha

@@preetibla like 10 around the world clockwise and anti clockwise, up down up down x 10 side side, diagonal etc. give it a go! Maybe it will correct for 1 minute… keep trying and the eye will be stronger
Okay maybe Bluelight isn't damaging but they should really add another point that you shouldn't use phone/bluelight gadget in the dark. This really causes eye strain and dryness. It causes the eye muscles to be be stuck in the "near vision" state which causes Myopia. While addressing such myths, it's very important to give the complete information because people may think that bluelight isn't damaging and start using phones while in bed, working on computers in the dark, etc. These things really damage out eyesight and it is a very important point to be covered here.
100% exactly what happened to me. Because of what this video said about bluelight I started looking at my phone in bed in the dark for 1 hour nightly until I started experiencing constant eye pain even seeing light flashes every day & night. Eyes blurry & burning daily that I regretted it deeply.
Who else started blinking like crazy once they mentioned “not blinking enough” ? 🙋♀️😆
Weirdo
Was searching for that comment, cause I was thinking, that i couldnt be the only one. 😅
@@strnbrgxprt1627 first thing I did too 😆😆
As a practicing Optometrist and Lecturer I can confirm all these facts and discussions are true. I wish all my patients would watch your video before asking the usual "silly"/misguided questions!
Simon, I thought that children DO see worse wearing glasses hence, Ortho-K, multifocus lenses, atropine, to slow myopia progression.
Whereas, if kids do nothing except get more powerful glasses over time - their myopia will worsen?
@@Allan-et5ig Actually two interesting seperate issues/theories. It has been shown that wearing the correct myopic prescription tends to stop the eye progressively getting worse (longer) COMPARED TO under prescribing/not wearing spectacles. Myopia will progress anyway through teenage years as the eye naturally grows depending on hertitage/genetics.
Myopia management as you mention correctly is a "new" way of considering how to stem the axial growth of the eye by tricking it by blurring the peripheral vision. This can be achieved with special spectacle lenses or contacts such as the Coopervision MiSight lens.
Atropine in a very low dose can reduce the power of the focusing system (accommodation) which again is thought to be a factor in myopic progression (actually perhaps the most effective method of slowing down the progression of myopia)
OrthoK is a method of correction of the vision, but without the peripheral challenges of spectacles - again some evidence to show this works well.
So... In summary... A massive topic area. Spectacles do not cause a prescription to get worse - infact it protects against some myopia progression (no effect whatsoever on hyperopia (very slight only) or astigmatism).
That's supposed to be your job. Patients ask a professional to educate themselves. Instead you make it seem as if its 'bother' and that's unfortunate.
@@Dorlinedainwen oh trust me I do. But with a limited time in a clinic (20mins per patient here where I am) it limits time between extensive questions and answers and then patient care of looking for eye disease. Hense why this excellent video would explain several of the most common myths asked every day.
@@MrSRMatthews How do they test whether glasses make vision worse?
Also what about the other question that I feel makes more sense rather than asking if they make vision worse: Do glasses prevent/lock out your vision from improving? Glasses help vision but I feel our eyes would adapt to having glasses somewhat.
Can you believe we are having all these amazing tips for free even better than so many docs out there. Thanks to these beautiful ladies.
My eye doctor did try to have me do exercises, but not for the eye, but to try and get the muscles behind it in line. After a while they said that it wouldnt work and I got my eye muscles surgically corrected.
My vision improved after watching this, you girls are hooot!
Another tip= if you feel like something in is your eye and nothing comes out, your eye most likely got scratched which can be helped if you go to an optometrist or you can deal with the pain and it should heal
Ayy thanks dealing with it rn
You can buy sterile saline (salt water)eye drops over the counter at pharmacy's.
If your eyes feel gritty and painful, like there is something in them,but they aren't red ,simply flushing them out with these will probably put them right.
If you still have a problem after a couple of days,and having used the drops as instructed by the pharmacist,you should see a doctor. You might have an eye infection and need antibiotic drops/ointment
Damage to the epithelial cells from the cornea also called corneal staining heals very quickly so just don't rub your eyes and it should heal in 24 hours. When the damage is deeper it can take a bit longer to heal. But if the damage is so deep that it penetrates the stromal layer then you will probably end up with corneal scarring
It can also be an allergen. Rinse your eyes out with eye saline.
I learned so much from this video! I love these calm, informative, and smart doctors!
Great video, some good tips and information!
Thanks!
Lots of great information. Thank you 🙏
The one on the right (camera POV) was really good at getting the general point across, and the one on the left, was really good at getting the more technical and in depth stuff.
Overall really great pair of Optometrists :)
Optometrist and opthalmologist* sorry lol, I know someone on their way to become an opthalmologist and he's very picky about the difference, basically opthalmologist's are full on doctors and specialize in the eyes, while optometrist can't do as much I guess? Pediatrist are in the same category as optometrist apparently, where they can't do as much stuff as other doctors. Keep in mind this is all second hand information, so I could be wrong about my explanations! Both careers are highly respectable!
@@alyssaurus17 Both are doctors, but think of ophthalmologists as the specialist performing eye surgeries/procedures, and the optometrist as your primary eye care provider that can diagnose/manage ocular conditions that do not involve major surgeries/procedures :) (I am an optometrist in the US)
@@ahhhhitsteresa where I am from (HK) optometrists study a different 4-year degree while ophthalmologists study a 6 year medical degree plus 6-7 years of specialty training- I guess they’re different everywhere?
@@dgfll Yes it definitely varies by country! Optometrists in the US are probably the most medically trained by comparison to other countries.
Eye exercises do not affect the underlying condition, but they can be used to teach a patient how to work with what they have as well as teaching / strengthening the eye muscles which helps with conditions like strabismus or nystagmus
I have amblyopia (I was also told I had strabismus) and was wondering about this. I hope I didn't wear a pirate patch to school for nothing...
@@Catlily5 honestly, wearing a patch while playing video games is much more effective.
@@Catlily5 For amblyopia patients, patching does help strengthen the weak eye!
@@SmallSpoonBrigade There weren't so many video games when I was growing up. And my father was against technology (despite the fact that he was an engineer). We had no radio, no TV, no microwave. We did have a ball attached to a string hanging from the ceiling. My mom would swing it in various patterns and I wore a patch and followed it with my bad eye.
@@PotatoPieYT Yeah, I do think the patch helped. My eyes don't work together and my bad eye cannot see 20/20 even with glasses. But my friend who never wore a patch can only see light and dark with her bad eye. Maybe her eye is just worse to begin with though.
They really are so knowledgeable… felt like the doctor on the left took most of the conversations and the Asian was more nervous at first, but they both loosened up and got more open towards the ends,!! So fun and understandable while being good at their crsft
I had a friend in her '50s with a pretty strong prescription. She did one of those "quack" programs with eye exercises. I totally thought it was silly but she was extremely diligent. I came back to visit her a year later and her prescription was much lighter. I visited a couple of years after that and she only needed glasses for very close stuff. A year later, she didn't need glasses at all--she could both read small print up close and see clearly far away and her astigmatism was gone. I think doctors can't find scientific evidence for eye exercises working because they can't find enough people that are diligent over those timescales. But I totally saw it happen. It's not a myth. I don't know how many people can do 15 or 20 mintues every day for years, though.
.... The myth is that the eye is being restored. Whats happening is you've exercised the muscles that focus the lens in your eye.
Reliance on that can cause eye strain that eye strain can be debilitating over time.
However, sometimes people just get lazy eye muscles and they don't focus normally.
I know, because I suffered through the eye strain.
Anecdotally, eye exercises worked for me too. I've been using Mark Warren's exercises where the idea is to train the muscles that control the lenses in order to relax, since phones and screens make them contract too often.
Another thing that might be useful, especially for people with dry eye like me is to use artificial tears. I used to have difficutly with visual clarity even when my diopters have decreased. It wasn't until medical check up that I found out my eyes were very dry. I've been using it recently and it has become near 20/20 vision, straight from -3. I hope I can improve my vision further
@@obnoxiouscommenter6194 how gradual was the improvement. I have been thinking about my eyesight and if I can improve them naturally, I am willing to try it out
@@tanirikamajumder4512 it'll take months, dropped from -1.5 to about -0.5. Even though the eye focus is much better, I'm still working on my poor visual acuity. I've heard it's more of training the brain to recognize edges
My vision also improved from -2.75 to -1.00 ... it's been 3 years of being 100% dedicated to trying to be positive, not stress etc. So yes, eyesight can improve but it requires a lot of mental focus and most people lack the discipline and energy. I also don't have diabetes anymore even though my doctor said it's incurable..
I wear contact lenses, and sometimes when they get dry and I rub my eyes they may get folded and get stuck usually on top of my eyes. It takes a little bit of effort to get them out, but you can definitely feel like there’s something stuck there, so I don’t know how that woman didn’t notice it to the point she had 4 lenses stuck in her eyes.
For me, whenever I got one too stuck in my eye, I would just put in a new one and close my eye and the old one would crash into it, causing it to come to the front so I can take it out, so I am confused how someone could get 4 stuck also.
As a beginner, Once I was taking out my my right eye contact lense as I got hold of it in my eyes I felt like it just dropped of my fingers in the bathroom, after searching it for minutes, my eyes were bot comfortable and tears would come and I was feeling like there's something stuck in my eyes, I was convinced that the lense might've fallen down and my eyes is itching due any bacteria or something, after 1hour of itch and sorrow, I once again looked the back of my eyes in the mirror and finally realised that it was stuck in my eyes.
I was hoping they would cover this completely about blue light: If it was really true that blue light was damaging to the eyes, we would have a blindness pandemic. But not bcoz of our digital devices but because of the sunlight itself. Sunlight has much more blue light than any of your devices.
Now, the only factor where blue light affects your body is after sun down. Our bodies are such that we don't expect blue light after sun set. So if you keep feeding your eyes blue light after dark, then your body will think it is still day and your sleep cycle will get messed.
That being said, turning on the night mode found on all the devices nowadays is enough. You don't need blue light filter glasses.
That's a good point. While blue light is very likely to cause retinal damage in older individuals (due to lipofuscin accumulation) digital devices are not going to be the primary source of exposure. Rather, all sources of bright light can (and will) cause this form of damage. Not just sunlight, but molecules in the sky also scatter both blue and UV radiation very efficiently (via Rayleigh scattering) meaning that simply looking up at the sky without orange-ish sunglasses can be more harmful than looking at a digital screen in a dark room (which, of course, is also potentially harmful for older individuals with more lipofuscin). That's probably the reason why we haven't seen significantly increased rates of age-associated macular degeneration in the digital age―after all, more screen time presumably means less time spent outdoors.
The character and intensity of blue light from a device (eg LED) and the sun are not comparable.
@@Acetyl53 yes. Intensity of the sun is much much higher. That's why blue light from screens is not at all harmful during the day. And at night you can turn on night mode on the device. No need for any special glasses.
Thanks for the information!
Oh. So, eye exercise does not work to correct your vision but just to let your eyes relax.
I’ve also heard that most people will eventually experience Glaucoma in their elder years due to how it’s also a condition that very commonly occurs with old age.
Bullshit

Pretty much I remember a government road safety PSA campaign from a few years ago that was focused on that problem! It’s still possible it might be not the most accurate if further scientific developments on the topic have been made since the campaign was first released.
Wow... this video was very helpful and knowledgeable. Thank you Dr. Banik and Dr. Tsai for such well thought out explanations. Both of you spoke calmly, nicely, very clearly and intelligently like true doctors should.
Snakes and salesmen will always speak nicely and put alot of effort in when they have a degree allowing them to convince you to spend hundreds on eye glasses. An optometrist running to remote areas can net up to 4k in a weekend for "charity work". Let alone their daily work
I have myopia. After doing eye exercises for a year straight, then getting tested again I was told my eye sight improved a fair bit and I have noticed it too. I wouldn’t skip out on eye exercises.
Yup they do actually work. These women should be fired

@@RaoulRamsaran nice sources. The way I did mine was through “The Bates Method”
@@reedyy_4114 do you mean you have been using the Bates method?
Can u tell us what exercises u usually do? I have myopia too
Please dont do any so called "eye exercises" from William Bates.
It will not be beneficial to your underlying problem if there is any. Seek an optometrist for a consulting and an examination.
I agree with the statement saying Blue Light IS damaging to the eyes. I am an Optometrist. Around 2007 Smart phones were introduced in America. I started to notice Blue Light Damage in the Lens of my patient’s eyes in 2009. The damage started in my 40 year old patients. This group of patients developed early nuclear cataracts due to Blue Light Exposure. Now, most of my 30 year old patients have early nuclear cataracts due to exposure to Blue Light. Many of my patients also started to become sensitive to light due to excessive use of Computers and Smart Phones. Blue Light Filters on phones and Computers have helped my patients tremendously.
Blue Light may not damage the Retinal Cells of the eye but in my nearly 27 years of practice, I’ve seen BLUE LIGHT DAMAGE the Lens of the eyes causing the development of Early Nuclear Cataracts.
I work 10 hours a day in front of monitor. Always watching YT or reading news on my phone before sleeping, in the dark. No glasses needed even after 10+ years.

Very informative. Great discussion! Thanks docs!
This video is soooo good!! We need more on other subject, such as hearing. 😁
I closed my eyes and listened to their voices. Angelic
Man, idc if it damages or not my eyes. The fact is my head hurts like hell if i do not wear my blue light filtering glasses
Both my parents had blue eyes and I was brown eyed until I was an adult. My eyes are now olive green/hazel with touches of blue about the iris. I also was born with nystagmus. I was told that even though nystagmus creates vision issues, it is actually a neurological problem.
I had PRK surgery 3 years ago and my vision was perfect for the first 6 months, and it became slightly myopic afterwards (something between 0 and -0.25 D) and I function perfectly actually. I don't wear glasses although my ophthalmologist prescribed me glasses to have them if I feel insecure (for example in driving).
And my eyes are now less dry because I learned to blink more in the recovery.
What was your starting prescription?
me watching this after losing my glasses and basically being blind:
as an optician myself the "the vision is getting worse when u get older" is still easier for the customer to comprehend then me explaining that the lens isnt as flexible in old age
Blue light, whether from the sun or a laptop, is very effective at inhibiting melatonin production - thus reducing both the quantity and quality of your sleep - I have found I fall asleep easier when wearing a blue light filter
As a person with red-green colour deficiency, I can say that my biggest two issues in life are public bathrooms and diode lamps on electronics. If I am visiting a bathroom which uses a green "vacant" symbol or red "occupied" symbol that has only colour and no text, I can't really be sure if it actually is green or red, so I have to check the stall door to know, automatically turning me into "that guy".
I also can't easily know if electronic diodes show green, yellow, or red most of the time, which can be annoying considering I work in IT and often have to work with switches, routers, and other gadgets that use diodes with changing colours to inform the user of status.
Society, start using blue vs red instead of green vs red please!
What about making a necklace pendant out of transparent red or green glass and when you are not sure, look through it to see if it gets darker or not?
@@charlieangkor8649 Interesting life hack! I should try it out!
I don't think I ever heard about blue light being damaging. The usual talk about blue light is more about it being bad before sleep because it doesn't let your brain know that it's the night and that it should prepare for sleep
About the "eye excercising".
As a kid, until the age of 10, I had myopia and astigmatism. Since my mother was (and currently is) a big fan of alternative medicine, in which I don't believe, she brought me to a specialist in Slovenia (we have Jugoslavian origins, so the language wasn't a problem). He told me to "excercise", looking at pictures with colored elements, for a minute, then to close my eyes for a whole other minutes repeating that picture in my head, open my eyes and read a text that I could read at a good difficulty level (being it small, distant, ...).
I didn't finish my whole excercise cycle, but since then, I've never been in need to wear glasses.
My myopia and astigmatism were medically diagnosed, and today I've been seeing various doctors and have my eyes checked every once in a while (for driving or whatever), 20/20 and not even a trace of astigmatism.
I've looked up online about the doctor and this kind of practice, but besides his internet page I wasn't able to find anything at all. Still today, I'm a very skeptical person, I truly believe the scientific method is the best way to understand things, and I'm looking for answers about the treatment.
No surgery, nobody even touched my eyes, no metications of any kind.
I've checked my diagnosis and the people that checked my eyes recently were doctors, eye doctors, that don't even know about my previous condition. No conflicts of interest.
I don't know anyone else that went trough the same treatment. There was other people there, other patients, but who knows who were them. It's been 15 years since those excercices, and I really don't know how I can see now. My mother isn't a good source of course, since for her it's all about the "glasses lobby".
Blue light gives me headaches when reading for prolonged periods of time. Before iOS added the feature to the native OS I used to get headaches all the time while reading on my iPad, even at very low brightness and even when changing the background of the 'paper' to grey or brownish/yellowish/beige, which was certainly more comfortable to my eyes than white, but it still hurt. When they added the night vision feature it felt sooo much better. I felt like pressure was relieved from my eyes, literally. I could read for hours without pain. I know they don't completely block blue light but just reducing it helps a lot.
I agree 100 percent

I have chronic migraines and blue light is one of the triggers. For reference, migraines can have different triggers for different people - anything from coffee to sound. Blue light is indeed not dangerous to the eyes as far as we know, but of course that changes if you have a specific eye or neurological problem.
I grew up in the 1960's, and the myth about sneezing your eyes out was around even then.
I would be curious to see a study on Thru-Hikers before and after. I have noticed on multiple Thru's that my eyesight will get better by the end of trail, and then worse when I am in my urban life. I would say I train my eyes to see up close (computers) when I am in town life, and then train my eyes to constantly look distant when I am on trail. I wouldn't be surprised if you can't train your eyes under normal circumstances, but if you change your focus for 12 hours or more a day for 6 months at a time, I wouldn't be surprised at seeing a difference.
Very educational video, I really enjoyed it. 💛
I always were sunglasses when driving in the summertime because I am light sensitive and also minimise the risk of getting blinded by glare and such on the road.
I am also *super* sensitive to that. People always think I would exaggerate, but sun glare really is in my top 5 list of things I really hate.
I love these doctors! I learned a lot 🥰
myopia has improved for me after eye exercise. athough hypermetropia can't be undone with exercise. needs more research. great video.
Smoothest voice to learn from. And it’s so easy to believe you guys because there wasn’t any pauses, no “uhm” or “You know”. A lot of confidence in what you guys are teaching us. Go girls!
Not questiong their competence, but the lack of "uhms" etc. is thanks to the video editor. There's constant video cuts/punch ins (1-4 seconds) and if you know what to listen for you can hear an even higher rate of sound cuts, where they've tightened it up.
7:34 I remember reading somewhere a while ago that there was evidence of treating farsighted people or whatever by having them not use glasses at all. I think it also suggested that wearing glasses contributed to the degree of farsight
That's true, once you start wearing glasses, it makes your eyesight worse without them. But my eyes were so bad that not wearing glasses would never correct them.
I am so happy after my lasik surgery - Next day I was reading ALL possible letters they had which goes beyond 20/20
If that's true, then you are one of the approximately 1% of people that have 20/10 vision.
You are very blessed and lucky.
@@funnyguy8161 I believe it’s thanks to great specialists in Zurich… I wasn’t cheap… But considering my profession and age think it’s a good investment.
