How did humans pre glasses deal with poor eye sight
Like how wasn't it selected out of our genes
If everyone has eyesight issues, no one does.
Humans pre-glasses didn't spend all their time indoors during early childhood, depriving their developing eyes of needed sunlight. Scishow did a video on this.
Maybe they died out because they can't Differentiate a python from branches of trees. natural selection is real.
Back then people didn't need their eyesight as much as we do now. They spent their days out in the field rather than reading and writing, so glasses weren't needed as much.
"glasses make your eyes worse!"
Well I already can't see jack without e'm so...
Canyon F bro you think you have it bad I’m Myopic
It’s getting so hard for me to see I can’t even see people if they’re far
I am far sighted and near sighted one on my right one on my left and it’s really crazy

Hey me too! I've managed to work around wearing glasses by just closing an eye depending on how close or far what I'm trying to read is.
I always noticed that after usually sleeping and not having glasses on I could see better first thing after waking up rather than taking them off after wearing them for a while
Same, specially if I'm off from any screen
Yeah same happens with me?
Sleep is when our eyes rest and they don't have to work hard to focus. Same thing that we feel rested after a good, long sleep but not after a run.
When I'm exhausted, my sight gets much worse. I'm convinced they are a band-aid for they real problem. A problem I have yet to identify.
Side note: Once, 3 days into a 4 day fasting, I could see and read clearly for 10 minutes. So, there's something to it, outside of misshapen eyeballs.
Your eyesight gets worse during the day due to drying.
How things change... "also just look cool" was NOT what I heard about my glasses while growing up
No one thinks that you look cool with glasses. They're ugly 99% of the time.
+William T Questionable. Some girls can look downright gorgeous with glasses on. Just depends on the person
Some. Most of the time, it makes you look worse. Just fix your vision.
agreed.
People with glasses just look normal. Plenty of people have glasses, and if you don't buy glasses that look ugly on you, you won't look ugly. Many people look better with their glasses anyways.
I love when people tell me that "GLASSES MAKE YOUR EYESIGHT BAD SO DONT WEAR THEM!!!!" Because, like, my prescription is -4.75... There is no "don't wear your glasses" for me, unless someone would like to get me a super well-trained dog.
brinapeanut XD .Me too . my parents would tell me to not wear my glasses . even though they know that my prescription is minus 5
brinapeanut I barely remember myself when I had minus 4 or 5, I was probably going to the first grade then, but I actually didn't wear glasses all the time then. In first grade I even forgot to take my glasses on when I went to school. It was pretty hard day then, I could barely see what was on a board then :)
I'm a negative 8 in my left eye and like a negative 5 in my right.. Tell me why my sister got so offended when I thought her five year old was a trash can? I couldn't tell if it was or wasn't lmao
Crippling Depression You could hardly see what was on a bord? I have minus 5 and I can not think of going for a walk outside without my glasses. I would get hit by a car right away I guess.

Lol 😂
That's funny

I remember back in grade school, before contact lenses were a thing, People would often wonder why people with glasses were frequently so smart.
Its not because smart people need glasses, its because smart people are smart enough to wear glasses when they need them.
No it's not... it's because "smart" people, or more curious people, or whatever other motivation there might be for reading books/comics/etc, are more likely to push their eyes through the feeling of eye strain, rather than dislike the feeling of eyestrain enough to put them off focusing on the fixed thing. Resting the eye when it is difficult to focus (or switching to an outdoor activity, giving eye muscles more practice at changing focus) stops the eyesight from deteriorating... or rather, NOT doing so causes the eyesight to deteriorate, as the brain doesn't get enough practice at aligning eye convergence with focus... being short/long sighted happens when there is a mismatch between eye convergence and focus (eg, for short sighted, trying to look at something further away will bring the closer thing into focus, when looking at that thing takes it out of focus)
Living indoors (only reading books or only watching TV) elongate children's eye. The intensity of outdoor's light is what controls eye growth. Children who is outgoing tend to play outside, and they're exposed to bright ambient light, so they grow eye normally, while the nerd who is reclusive will stays indoors, and they're not exposed to natural light, so they will need eye correction later.
xponen so how would u fix myopia? Do u have an idea? Or should I say 'eyedea' . (Sorry. i couldn't help myself)
Then I must've been dumb to just keep going without glasses for nearly the first half of high school.
They eventually caught me when they did those vision and hearing tests.
@Atlanta , I would wear glasses, I'd do nothing fancy.
Got a glasses ad right before this lol
Anna Skupin Contact lenses for me.
not a coincidence, it's targeted advertising
Anna Skupin just use adblock like me
me too, well in two days jaja

When my eyes tear up, I can see clearly... why is that??
living dead the salt in our tears make our eye muscles relax. I dont know if that’s correct but some dude on the internet told me
it's due to the water in your eyes being able to refract light in a precise way to reach your retina. It's rare to happen but I myself have managed to do it sometimes. Hope that helped anyone.
When I water my eye I can see clearly
I can't
@@bettycrustae5518 after waking up, apply morning saliva in your eyes it will improving your eye sight (you can google it) 😂 eye exercises helps to improve eyesight, but i am addicted to my mobile... And these online classes!!
"And also just look cool"
You got that right!!
Glasses just make you uglier 99% of the time

I'm the troll or OP is a troll?
+William T not all the time...
Hence "99%"
The myope club!!!!
Primavera That's what I call my family, we all wear glasses, kids and adults
Mid Night Haha, same goes for my family. My parents, me and my two brothers all wear glasses :)
Can we change the club name to "Can't see shit from far". Please?
that would be a lovely name change xD
Primavera Omg Same ! Me and My Mom Were Glasses
I bet the farm that 95% of the people that viewed this video are all FOUR-EYES who checked to see if glasses really DO ruin our eyesight 😂
GreenFlash Sunset Wha-what?
Noice Kung Fu Panda agehao, my dude. 👍
😂 you caught me
I really wanted a free farm but alas, I am wearing glasses.
W-What are you talking about? **nervous laughing**
i know someone who told me that they stopped wearing their glasses during the summer because he lost them. his eye sight started to return to normal without them and when he finally got new ones they just made his vision blurry when he put them on.
Its start being blurry because when you have glasses you dont need to focus on so far things. I started not uisng my glasses and i see little improvement(but i still use them when i use devices or going out)
He found a way to come over it! But this methods dont went viral
Sounds like Peter parker
Almost identical story for myself. I stopped wearing glasses during middle school during the summer, then got in the habit of just not using them during the school year. My optometrist tested my eyesight and said it improved somewhat, recommended some eye exercises, and gave me reading glasses. Eventually I stopped going to the optometrist and stopped wearing the reading glasses. I’m now 32 and still don’t wear glasses and read all the time.
Same for me .... But I think it only works for less power because you dont have to strain your eyes as much ... And eyesight gradually improves ... But for higher powered glasses you have to strain your eyes and that's what ruins the eyesight... This is from my observation
My eyesight is super blurry so when I see a cockroach, I take my glasses off, then i can kill it thinking it's just a hairball
What?! 😂
😂😂💯
So you kill hairballs?
If my vision was mildly blurry and reasonably okay to deal with without glasses, I would just go without. But being nearsighted with a prescription of -3.50, I have to wear them all the time. The only time I take them off is when I'm going to bed.
Is -2.50 good?
And that’s the problem...your wearing full correction all the time...when doing closer work you should be wearing weaker glasses just enough to create a bit of blur to give your eyes some challenge to try to focus...check out Jake Steiners videos😀
my prescription at most powerful is in the right eye and is -0.75
I am different my left eye is -2.5 and right eye -0.5
I can see pretty much same when I open both eyes
When I close my right eye everything become blurry
I’m getting glasses next week but my prescription is really low.. in my right eye it’s -0.75 and in my left eye it’s -0.50 but the doctor told me that it’s best to start wearing glasses so my eyes don’t get worse cuz just 7 months ago they were fine
As an astigmatic person, I feel left out.
im an optician. you can have astigmatism whether you're nearsighted or farsighted. it just means your eye instead of being shaped as a round circle, its shaped more like a football. i have astigmatism in one eye and my other eye doesn't
Feel your pain, both eyes bad af
I'm a physicist (who has had eye correction, for myopia, since I was 9) with some knowledge of both geometric and wave optics, and Irene is right - astigmatism cuts across near/far/correct-sightedness. Optometrists & opticians often refer to the overall correction as "sphere," and the astigmatic correction as "cylinder," because they correspond to lenses of those shapes.
And you can, in theory, have any amount of either, independently of each other.
But Irene - is it the shape of the eyeball/retina or the eye lens, or both that's ellipsoidal? I can see how either one would result in astigmatism.
it can either be caused by the cornea or the lens
Right; of course; the cornea is the first optical surface encountered by incoming light.
I started having vision issues when I was 13-14. Not bad, but had problems seeing the whiteboard in class. I wore contacts for about 8 years until 22 yrs old. I then wore glasses for the last 7 years. My vision actually improved by 0.5 in both eyes over the course of my twenties. Just providing some level of proof that glasses don't ruin your eyes. They actually may help!
Hey is it real? Did you wear them all time? I'm so excited please reply me!!! I really need answer. Please mate reply me!
You are one in a million and I doubt your anecdote as it contradicts science.
The eye goes myopic for 2 main reasons:
1. Excessive near work
2. The use of minus lenses for near.
You do these starting at age 8 and you'll end up with 6 diopters of myopia by the time you are 20, period. This is shown by studies from 1975.
If you instead wore plus lenses as a kid for all excessive near work you would have never become myopic.
Don't tell your eye doctor! They'll tell you, you got early signs of presbyopia
mine is the opposite. started wearing glasses to see whiteboard clearly, now someone standing close to me is blurry
I hate Glasses; I have one eye that is Near-Sighted, and the other is Far-Sighted but my Brain tries to Autocorrect both Eyes and I just wind up with being unable to see at any Distance.
I have one eye that is near sighted and one that is blind.
🤣
Hi, This is a serious suggestion. Ask you doctor to prescribe 'mono-vision' glasses. That is what mine does. One lens corrects for far vision, the other for near vision and the brain resolved the differences between the two images it receives. I can read books and I can read traffic signs with the same pair of glasses and without a bifocal or graduated lens. If you current doctor can't give you a comfortable correction, try other doctors. Ask friends who wear glasses and really like their doctors who they are going to. I found my best doctors that way. Also, ask the doctor if it is possible that you have an astigmatism in one or both eyes. A subtle one can be easily missed and if the lens doesn't correct for it you won't feel comfortable with that correction. Best of luck!!
Another thought, one strategy I use it to bring an uncomfortable prescription back to the office right away. I know I'm hard to prescribe for, so I start by offering to pay for another lens because I know there is a high probability that I answered incorrectly when they were flipping the lenses during the exam. But so far the bad corrections have been the lab's fault. In once instance they swapped the left for the right, in another they forgot to add the astigmatism correction. Labs don't always get it right. And I've found a good doctor is OK with being questioned as long as I'm polite and offer to work with him to make the glasses right.
@@acninee I've had mono vision glasses for 2 days and it feels weird
I just got my glasses today, when i tried them on, i was blown away. The eye doctor said i only needed them to see far away, but when i put them on for the first time i realized that i had been seeing the world slightly blurry forever and i never knew it. I like wearing glasses :)
can bad glasses give you headaches? what about other eye problems not specifically related to the glasses themselves?
If they put undue strain on your eyes, yes they can give you headaches.
You won't fool me with your fake passport!
fidelio little potatoe man!
Very bad glasses can cause you to be hit by a bus. Glory to Arstotzka!
Well bad glasses may cause you to squint more to see clearly and thus result in headaches. For me, before i got glasses I was squinting a lot to see distant objects and had a lot of strain induced headaches.
When I first read the title I thought it was, "Do *Gases* Ruin Your Eyesight?" After I PUT ON my glasses I figured it out.

REEEEEEEEEEE
My eye doctor scientifically labelled me "blind as a bat" haha!
Sarah Jackson he called me legally blind 😂 it wasn’t that bad though!
Those dramatic eye doctors!
GlitchGaming45 I’m pretty sure I was legally blind as well I’m 14
My eye doc said I will not be able to see clearly until and unless I don’t get the lasik operation 😂
Lol! Mine, too. He told me the best way he could hurt me would be to throw away my glasses. I'd be totally screwed.
Of course they do.
Starting with the first minus lens they gave you!
typical propaganda from Big Glasses
ryanhatesgirls - bespectacled mafia!
I don't remember cavemen needing glasses!
ryanhatesgirls the media are controlling our eyes. keep them shut!
too true
I'm glad you all see the truth
THEY DIDN'T FIGURE THAT OUT TILL 2002, WTF
Marie P my thoughts exactly
And they still don’t understand...myopia can be reversed 😀
We sent people to the moon for goodness sake but couldn't figure THAT out 😂
The 2002 study is flawed and discredited
They’re clueless till this day!! These people just want you to buy glasses to steal your money
stopped wearing glasses, eye sight got better.
even stopped having it required to drive.
so... dunnoo....
You don't use glasses no more
Well at least you don't have an astigmatism. Where you're born with it.
Same same same
nice anecdote
I underwent a lasik procedure 3 months ago, no more glasses for me! ... Until I get older and need reading glasses. Because ageing sucks.
My wife had it done last summer and she's a happier woman now :)
So thankful for technology :)
What was lasik like? I'm considering getting it when I'm older. Also, were there any side effects and did the procedure hurt?
Aishah Anjum I'm pretty sure it won't hurt at all, but you will feel pressure on your eye.
There are some risks since it isn't 100% safe.
Aishah Anjum, for me, the procedure doesn't hurt at all. Your eyes are completely numb and 90% of the time you can't see a thing. It will however feel like they are burning for a few hours after the numbness goes away. For a month or two you'll probably see halos on everything. It's not really a big deal though. I'm glad I did it.
Once I have a steady income, I really need to consider it. My eyes are terrible. Do you mind describing your eyesight before? I briefly talked about lasik with my doctor, and he made it sound like my sight would be leaps and bounds better, but I would still need glasses.
I've heard myths that claim that hearing aids make you go deaf quicker in a similar way, which is ridiculous. All they do is make the sounds loud enough that the hard-of-hearing person can hear properly. There are no "hearing muscles" that get weaker and more dependent on the hearing aids. Seriously, who makes this up?
If you crank them up too high, then yes. They are like headphones, play them too loud and they will damage, but most people are smart enough to not have them maxed out at all times, including in thunderstorms or rock concerts
Depending on the reason for the hearing loss, the use of hearing aids can lead to further hearing loss. If you are using hearing aids due to hearing damage from prolonged exposure damage, then yes hearing aids will continue to cause damage over time since you will keep needing to increase the volume over time.
Citation? Some hearing aids don't even increase volume as such, they remap frequencies into a range the ear can hear.
Some shift the frequency to a less broken range, others are no different than a small audio system that takes in a signal using a microphone, amplifies it and then sends the now amplified signal to the speaker that is in your ear. This last section is nearly identical to headphones where you control the gain (volume increase). Running it to high may break your eardrum, but most of the time it helps with hearing. Citation: google it for basic hearing aid operation and also, electrical engineering student taking a signals and systems course
Eh? What did you say? Speak up! lol :)
Actually, in science, long term, uncontrolled close work create the problem.
The minus lens, simply makes matters worse.
The optical industry is a billion dollar industry!
You need to look at the real studies that are being suppressed and ignored.
Are you saying that is it okay to not wear glasses even when you have a high grade?? Wearing glasses really lowered my self esteem that sometimes I decided that I don't wanna wear them always but I'm worrying that it may worsen my eyesight?? I'm confused...
@@myyy7982 wearing minus lenses for close up work can make ur myopia worse. using it for seeing far objects is fine
@@hanafirjl what I don't understand can you please simple your sentence.. I don't understand deep phrases about these types of things..
@@myyy7982 have you try checking jake steiner or endmyopia.org there are good stuffs there
@@hanafirjl "wearing minus lenses for close up work can make it myopia worse" Wdym by that?
So the real question is - how the heck do you cure myopia? I've been removing my glasses constantly so that my ciliary muscles could get some exercise, but now you're contradicting it. Please let there be a cure soon :(
EccentricSilence Lasik surgery. It uses lasers to correct the shape of your eyes and works really well for myopia. You're only supposed to get it once your eyes stop growing though.
***** Yeah but I don't like laser surgery. I'm aware of it and its risks.
Lasik surgery, or if your prescription is really bad lens replacement + lasik surgery, is the only "cure".
You could wear contacts if you really don't like your glasses?
Joelle Jansen Contacts require too much care and attention.
EccentricSilence Well, there are lots of options nowadays, night contacts, dailies etc. Maybe have a chat with your optician?
Damn i cried the whole night about just thinking the good times i had without my glasses when i wasnt being called a four eyed nerd, when i could have wore sunglasses... ah good times
endmyopia.org
I'm crying all day :') I had my glasses at age 10. We didn't even have pc in our home at that time. I was going out and playing with my friends all the time. And my myopia went higher and higher. My family is healthy so it isn't genetic. I'm just swearing god all the time because I didn't do anything I didn't deserve myopia. I was playing games outside we didn't even have pc or mobile phone in our home!
Same 😪
Why are these guys so insecure about their @ss cheeks vision lol, people wearing glasses aren't new, if you have a friend that make fun of you for being a four eyes nerd just dropped 'em, they could also be joking as well.
Near work causes myopia. Minus lenses aggravate myopia 4 fold by making everything closer to you (that is what minus lenses do optically).
Well shown by science, and very sad not many are familiar with this / care about it yet billions of people have their eyes destroyed by minus lenses.
Yes. Near work causes myopia, 100%. Minus lenses are then prescribed but when used for near make things even closer hence vision worsening over time. Minis lenses accelerate the process 4 fold.
Nearsightedness is preventable + partly reversible if you're not a high myope
I have an identical twin sister. We both were prescribed glasses in 3rd Grade for nearsightedness. I always wore my but she hated glasses and barely wears them. My vision has continued to get worse and every year I need stronger glasses. My vision is now 20/120. My sister's vision is 20/40. I blame hours of looking at a computer monitor with glasses while my sister didn't.
I'm nearsighted in my left eye and farsighted in my right eye, as well as having astigmatism in both eyes
This is just superb, been searching for "how to decrease eyesight naturally" for a while now, and I think this has helped. You ever tried - Patlarny Quit Glasses Principle - (should be on google have a look ) ? Ive heard some pretty good things about it and my m8 got cool success with it.
@@thejunior9303 this is a bot
Whut?
Got my eyesight checked today and figured out I’m nearsighted. 😭
I finally found out why the eye doctor gave me glasses that didn't improve my vision when I was a kid. thank you
I always wonder, how did human race deal with this poor vision in ancient times??!!
Athul Ghosh bates method it heals your eyesight naturally
@@hoyeonpark9423 what is that?
Bates method its scam
They did not have poor vision because they did not wear glasses
Well that's probably why they created glasses just like other medical improvements
This is the kind of click bait I love because he answers the question almost immediately. It's just great.
What about overcorrecting then?
Edit: Did anyone read my own reply before replying yourself?
Emil Ellénius you become the opposite. Like if you overcorrect your nearsightedness you become farsighted.
Paputsza Maybe so in very young children. Definitely not in adults once the eyeball has fully developed. All over or under correcting will do in adults is cause unnecessary fatigue, making your eyes feel tired, sometimes causing headaches.
I believe Paputsza said you become farsighted as long as you are wearing the glasses, not in long term
Paputsza Yes, I know that very well; my mother and I are both nearsighted but she uses stronger correction and I've tested her glasses. What I really meant was that in the study they compared undercorrection and the right correction but why didn't they test overcorrecting? The results would probably be the same as undercorrecting, but why didn't they include it in case it would actually be beneficial (I still have a hard time believing that would be the case but still...).
You gain super vision and can see through walls.
... So as a kid my eyesight was perfect, but now I need them to see long distance. So my eyes were normal and then they became long?! So weird! Reality is weirder than fiction! What in earth makes your eyes become longer?
Lorna Blackmore that's normal
You grew taller.
He’s wrong my eyes got worse over the years when wearing them and finally when I took them off for a few months, my vision got better
Exactly!
So there’s two reason for this
The first one is that you could be doing different things in your normal life with glasses than without glasses
The second reason is that maybe what he said didn’t apply to everybody
@@augusthuang4589 No it's because glasses ruin eyesight. They are just refractive glass that distorts visual perception and the eyes accommodate for that refractive error. There's many published scientific research papers on this topic. And this one CZcamsr Jake Steiner goes really deep into it. The whole near-sightedness epidemic is caused by glasses.
@@professional.commentator hello I'm wearing glasses since when I was 5
I'm gonna be 14 soon, I am myopic
So did glasses ruin my eyesight?
@@cupcakepokrin Yep! You had pseudo myopia before you were 5 years old from the screen time probably. Then once you started wearing glasses it became lens induced myopia.
00:17 - but the lens of our eye stretches naturally when our ciliary muscle is in a relaxed state (as it is for distance vision). It is when the lens is being pushed so that it bulges out that the ciliary muscles are working hard. That is why a lot of close up causes eye strain. The statement you made at the beginning of this video only really applying to people who have presbyopia and wear their reading glasses excessively, never challenging their eyes to do close up work. For anyone who has myopia, or is short-sighted, wearing glasses forces the ciliary muscle to stay tensed up, until our biology finds a short cut, which studies suggest is axial elongation, or perhaps choroidal thickness. If you are shortsighted and you wear glasses it sure does make your eye sight worse, and if you wear them for close up work it is likely to get worse quickly.
Hi Gem,
Pure Science:
You put a strong minus on the normal eye, and in 9 months you have a seriously myopic eye.
Yes, the minus only makes eyes more negative.
ALWAYS.
Should I stop wearing my glasses while on electronics? I'm only 1.0 in my right eye and I can see fine without my glasses. I take them off while not on devices. My left eye has 20/20 vision.
The idea that glasses worsens your eyesight in the long run is true. Trust me I wear glasses. Even within the first two weeks of me using them as a kid, I could tell the difference. After two weeks of nonstop use, I went two weeks without them. In that time I noticed how my eyesight reverted back to normal.
Another interesting fact, no two optometrists will give you the same eyeglass prescription. I went to three different ones once, and each one gave me a different result.
If those facts don't bother you enough, my dad took both me and my brother for glasses the same day. We both walked out with glasses, however, he stopped wearing them after a couple of months and I didn't, I kept going. Funny how he was diagnosed with a more severe eyeglass prescription than I was. Twenty years later. He doesn't use eyeglasses and has never really felt like it, and I keep getting thicker glasses each time.
In my opinion doctors are not any different than a person trying to sell you a car or an insurance policy. In the end, everybody wants to have a nice life, and people usually require money for that to happen.
Don't get me started with dentists, the biggest scam artists. If you want a healthy mouth and teeth, going to a dentist should not even be an option.
exactly dude just look at the difference between orthotropic and orthodontic orthotropic focusing on your airway and breathing where orthodontic just focuse to keep the teeth straight even if it will make ur jaw set back or smaller airway
So let me get this straight, according to you, glasses don't help, doctors are salespersons, and dentists are scammers. I, err, uh. Assuming the worst about people, discarding science, all in the name of your personal (and anecdotal) experience is absurd, but okay.
The fact that "you can tell" that some glasses somehow hurt your eyes doesn't say much. Even if that is somehow true (assuming you remember correctly, which sounds doubtful), it only proves you got prescribed a pair that didn't work for you.
"In that time I noticed how my eyesight reverted back to normal."
How would you know what normal looks like without tools to measure it, especially as a child? Normal for a child who needs glasses is likely still not great.
"Another interesting fact, no two optometrists will give you the same eyeglass prescription. I went to three different ones once, and each one gave me a different result."
This isn't so much a fact as your personal experience which you have generalized to all optometrists for some reason. When I go to a different optometrist, they look at my eyes, and can find the same results as other optometrists. I wonder if you really went to see professionals, quite frankly.
"He doesn't use eyeglasses and has never really felt like it, and I keep getting thicker glasses each time."
Not feeling like using glasses doesn't mean you don't need them. Some people have cancer and don't feel like getting treatment. Some people don't feel like getting vaccinated. It doesn't mean they wouldn't stand to benefit from it.
"In my opinion doctors are not any different than a person trying to sell you a car or an insurance policy. In the end, everybody wants to have a nice life, and people usually require money for that to happen."
You may want to look into the ethics and deontology of medicine.
Thanks for sharing! It's an unpopular opinion but it's true! I will not wear glasses
Wearing glasses does not make you more qualified than actual optometrists/ophthalmologists.
when I used to be a kid I could see fine, I use my glasses all the time and now I see blurry with out my glasses.
And remember get an eye exam every 2 years my optometrist gave me a lecture because I dint go for like 5 years and my glasses needed to be a lot stronger
I like this guy, positive and always tells me what I wanna hear
Astigmatism ftw, I can't live without my glasses
There is one exception: prisms
If you're eyes are crooked, and you get prescribed prisms, that's usually fine if your eye muscles are working correctly but are just slightly off. In my case, it was a slight weakness of the eye muscle, and prisms actually made that worse, and I have since lost the ability to correct that weakness without professional eye therapy, which I can't afford.
I know this isn't on the clear -> blurry scale, but it does affect your vision significantly, since it can produce double vision, or your brain will ignore one eye when it is crooked as such. This destroys depth perception, and can make driving an impossibility.
Wearing full prescription glasses for close-up will ruin your eyesight. This has been demonstrated in studies. Once I realised this and learned active focus, I was able to reverse my myopia from -2.00 to now seeing 20/20 with my naked eyes. I help others do the same at my channel and with my course. People need to know there are alternatives.
How? Myopia cant be reversed. I wanted to know i have -2.75 prescription
Rip to those kids who now lost their vision.
Me: “Hey Guys, I’m Myopic”
Everyone who doesn’t wear glasses: “Nerd”
Neat
Cool
Glassed DO make your eyes worse IF they are over prescribed (too strong). Which is frequently the case. Glasses cause no major harm if correct strength. If under strength just a tiny bit (0.25 diopter) then your eyesight may actually improve!
for the sake of eyeglasses industry, yes, you need glasses
Just make sure you don't mention Lasik then lol
If you know other remedies, please share with us. People that use eyeglasses, use them becouse they need to see and they don't know anything better.
Maisunadokei1856 thank you. I will. :)
Lucia Tat look up eye exercises and when its sunny go outside and stare at far away things
Cedric Rheaume thank you! I will try!
Do contacts make your eyes dryer? My mom and I both have problems with dry eyes and we suspect that it may be the contacts since the problems only started when we got contacts. No one else in the family wears contacts, and no one else has this problem.
Melissa Geckensmerf I thought I had a problem with dry eyes with my contacts because they would irritate my eyes and be really dry by the end of the day. And they are dailies! Turns out the contacts were just making my eye allergies worse. I use prescription eye drops for allergies before putting in my contacts and it's helped a ton!
Have you tried switching to dailys that might help
Melissa Geckensmerf I've heard that contact lenses can sometimes make the issue more apparent because the eye isn't getting as much oxygen. Older people tend to have dryer eyes so your mum might want to use some lubricating eye drops to help. If your eyes are just as bad, make sure you're using the best contact lenses you're able, otherwise drops would be a good idea for yourself too.
It might be that your eyes are irritated by the contact lenses or the contact lens solution (for example; I was mildly allergic to a particular type of contact lens solution).
Also, some contacts are more comfortable than others. Rigid contacts tend to be rather uncomfortable, soft contacts tend to be better. Next gas permeability of the contact is important, the higher the "breathability" of a contact is, the more comfortable it is. You should probably ask your optician.
If you don't want to go to your optician, you could always use eye drops to alleviate the symptom...
Omega 3 capsules is great for dry eyes
I love how you roll your eyes to the ceiling (and beyond) with this myth lol!
Wearing glasses frequently can make you more dependant on them though. I'm a bit long sighted and am mostly fine without my glasses, but my eyes get strained quite quickly from focusing. The less I wear my glasses, the longer my eyes can go without getting strained as the muscles that focus them get used more. The video briefly touched on this, but it's quite a significant point for people with vision like me. When I'm not wearing my glasses I can consciously move the muscles to focus and unfocus my eyes, which from what I gather a lot of people can't do!
Oooohhh that's why my vision is getting worse!!
MY EYE IS GROWING!
I love you guys. I don't watch basic cable anymore. I just watch shows on the internet and I literally watch you guys at the least every other day.
My vision used to be terrible. I couldn't see facial expressions from 5 feet away. I couldn't tell if people were looking at me or someone beside me. I couldn't tell if they were smiling or frowning from a distance. It led to a lot of awkward situations, needless to say. I lost my last pair of glasses 10 years ago and i haven't worn a pair again since then. My vision has improved objectively. I had my vision tested several times and the difference is significant from the time that i last wore glasses until today. I'm not sure if that is due to the fact that i stopped wearing glasses or my body is just aging and my eyeballs are changing shape
All I know is my eyesight was 20/100 prior to the military. The job I wanted required no worse than 20/70. I threw away my glasses, did a lot of eye exercises, practiced keeping my eye muscles relaxed, etc. About 6 months later I qualified for the job I wanted with 20/40 in both eyes. If I kept up the exercises, my vision would hover around 20/30-20/40. If I stopped doing them, my vision would hover around 20/60-20/70. When I got out I started wearing contacts again, and my vision has slowly deteriorated to over 20/100 again.
what are the exercises
When I was young, my eyesight was around 20/15. Then around 12 years old, my vision started to degrade. My prescription was getting stronger such that I was getting new glasses every year. Each time, I would get glasses that restored my 20/15 vision. Then one year when I was getting new glasses, the guy stopped at 20/20. "I can usually see better than this", I said. "Well, I could keep going, but since you do mostly computer work, it's just going to give you eye strain as your eyes have to work more to focus up close."
I left that day with two pairs of glasses. A distance pair for driving and sports, and a pair that corrected me to 20/50 for computer work. My prescription has been stable since then. I was 26.
The role the eye strain played in my changing prescription is unclear from just my experience, but the eye strain is real. If I forget my computer glasses and try to do a full work day using my distance glasses, it's very uncomfortable after about four hours. I suspect there are a lot of near-sighted people who would be a lot more comfortable wearing a weaker prescription at work.
Hi if you're still even in this account i'm 12 right now and my vision got worse but mostly in my right eye i currently have glasses but it only improved my right eye a little. I would like to have some tips to improve my eyes because i also have to work on the computer for school and projects.
What does a near sighted gynecologist and a puppy have in common?
A wet nose.
So when I was 5 I lied to my parents that I needed glasses (cuz I did, okay?) and i got a prescription higher than my actual eyesight, which is what I believe is what damaged my vision. But can this happen?
Yeah your eyes can readjust to compensate for stuff so you likely did ruin your vision by doing that.
@@_loss_ are you sure about this? If so, can you send me an article/paper or something on it? I'm very interested in this topic and want to research further into things
As a child I used glasses from ages 10 to 16 and then one day I just stopped. It affected me for the first couple weeks of months and then my vision felt focused and normal after a while so I did not go for a replacement. I did a eye exam for my exam at age 19 and my results showed that my vision was 20/20. I am now 32 and I have been doing an eye examination, as a part of my annual medical check-ups, for the past 8 years and my vision still remains perfect. Can you explain what happened in my case? Just curious. Ps: I was teased a lot by one specific person for wearing it as a child.
Same with my husband. He needed glasses as a kid but in our first year of wedlock they broke. We couldn't replace them so he did without now his eyes have corrected themselves and he has 20/20 vision
Yeah. I don’t completely agree with what he’s saying in the video.
Matthew Medeiros what's your eyesight?? Mine is -9
Can u please tell me why did u just stopped wearing it?
-9 !!!!!! It is really big number...My number is -4.....What is your age? How often do u need to change ur prescription ?
My eyesight is 20/400. Even if it did make my eyesight worse over time, I don't care. Without them, I literally cannot function.
Miss Adjusted my vision is like 20/400 and I can make basketball shots from the free throw line or 3 pointer if I was stronger also I can walk without them run but cannot see the damn whiteboard
@@luiscortes4651 mine is 20/100
So why doesn't feel like my vision is getting worse when I take off my glasses for a brief second when I look myself in the mirror only to see a blurred person?
Yes! Let's not trust the professionals who actually study this stuff, let's just go off our own personal experiences! Clearly the people who work in this field night and day are wrong....
Perhaps they know the answer but let's not forget that nobody will be contributing to their coffers if the truth is made known
They don't have anything better to offer so I will just do my own thing.
Endmyopia.org
This video is really bad, john green contradicted himself by both saying weak eye muscles don't cause bad vision, and saying that eye muscles can adjust for different types of eyes. Just like any muscle EYE MUSCLES CAN BE STRENGTHENED. There is something called vision therapy, which are exercises for your eye muscles. Many people including my own brother used vision therapy and don't have to wear glasses anymore.
QQ:why are some people can blur and focus their visions at will?
Yes! I've always been able to do it, but I never actually wondered why. They should really make a video explaining this!
I think that's just dilating your eye, although this is a random uninformed guess
I can focus and blur my eye too but I didn't tell it to my family and friends...
+Diplogod Oh, Hm, well they should still make that video
That's good
Yep, that's how they ruined my mom's vision. She had slight myopia, but the underprescribed glasses just made it worse.
Went for a standard check up and my optometrist realised I had glaucoma. Saved my sight. Thank you John.
better eyesight = fewer babies.
think about that one.
Because you’ll see that people are ugly? Lol I like that.
lmao
That’s good because overpopulation. *looks at millions of homeless kids out there*
That's a good explanation for why evolution hasn't weeded out poor eyesight.
Poor eyesight means I am superior than you and can kill you more easily= think about that
Thats exactly what a guy with glasses would say
From what i know from information there hasnt been enough studies done to confirm or call it a myth.
I dropped my phone in the water now I need glasses... I lost all my contacts.
lmao this needed more likes than it got
I'm not wearing my glasses right now, because I was hoping that I would be able to correct my eyeball shape. Thank you for crushing my dreams Scishow.
My first glasses really hurt my eyes for a long time until I realised that the orientation of the lenses makes a huge difference. By twisting them round in various dimensions the glasses no longer hurt my eyes. I am astigmatic, but it's possible this might work on all glasses equally. You can flex your glasses from side to side, and then up and down (each side in the opposite direction), and see if your eyes feel more comfortable as you do it. This will move the centre of the lens, and therefore has the effect of changing the direction that your eyes are pointing in. If you are astigmatic you will also need to rotate each lens along the axis of your line of sight to find the optimal orientation to give you maximum focus. It might not be the same on each side, and it could vary over time.
I realize that this was literally 5 years ago but you're absolutely right! Astigmatism and axial orientation go hand in hand, especially if you have a particularly high astigmatism (cylinder power). I hope you managed to get some updated glasses since then lol ☺️
That's the question I've asked myself many times in recent days, developing myopic vision. Big thanks for debunking that myth, SciShow!
So nearsighted that I can't see the computer screen without my glasses or contacts.
Sorry, that might be right for many people, but I can assure you my eye deterioration at least was accelerated when I started wearing glasses. In my case, I had better than 20:20 vision (better than 20:10 at one point), but focusing up close started causing me headaches. Getting glasses fixed the headaches, but within a few months, I could no longer focus up close without them.
I realize that the hardening of my lens was responsible for the increasing difficulty for my eye muscles to shape it for focus. However, getting glasses meant the muscles no longer had to work that hard and/or the lens no longer needed to be flexed to the same extreme, so it became impossible to focus up close without the glasses.
Obviously, eventually I would have been unable to focus up close without the glasses eventually, but the glasses definitely accelerated the process.
Now if someone could only invent a material with nearly the optics and flexibility of my younger lens, I could have that wonderful eyesight back...
Lol. Due to an incident in 1975, I no longer have the use of my left eye. Some time in the mid-1990's, I started needing corrective lenses. Does that make me a "two eyes"?
Lol
Using your phone while wearing glasses causes the ciliary muscle to spasm and lead the eyeball to grow even more.Look up the term( Lens induced myopia).
A strong minus lens at 20/40.
Answer = yes!
Solid science.
ODs live in a dream world of denial.
I strongly disagree based on my own experience. I was prescribe glasses back in secondary school for myopic, but it was minor. I found that I can't see as far once I get used to the glasses, hence I stop using it, and my vision remains the same 20 years later.
So nothing changes？
That's called age.
Its called blur adaption look into it
my wife got a stronger prescription 4 years ago that gave her headaches, she refused to wear them despite her eye doctor pushing them on to her. Today she still wears her old prescription and has roughly 20/30 vision (did an eye test yesterday). Had she used those stronger prescriptions 4 years ago, i can guarantee her eye site would be much worse today. I don't know if reducing ones prescription reverses but blindly following optometrist suggestion and not questioning their motives is not wise either.
Also I first got glasses in 2010, very weak prescription and stayed that way until 2016. Starting in 2016 I decided to just wear them all the time because I liked the frames I got and everyone gave me compliments. From that point on my prescription increased about 0.50 diopters every year.
HA! Jokes on them: my eyesights ALREADY ruined!
When I got my first eye glasses prescription, my eyes were perfectly normal. I remember them putting drops in my eyes and they said it was to dilate my pupils, but then my eyes never went back to normal and I had to wear glasses. Eventually those glasses didn't work anymore and my eyesight kept getting worse and worse after each new pair. So eventually I decided to try not wearing my glasses at all. When I haven't been wearing my glasses for a while they feel fine and even though I can't see very far away, I'm fine without them. But when I do wear my glasses for a long period and then take them off, my eyes feel very strained and everything is ten times more blurry than they usually are. I feel like my glasses are actually worsening my eyes because this happens every time.
Do you ever wonder why you first got prescription glasses in the first place if your eyes were perfectly normal? Your story is off to a rocky start. It strikes me as far more likely that you got prescription glasses because you needed them, rather than some mysterious drops that forever damaged your eyes.
"when I do wear my glasses for a long period and then take them off, my eyes feel very strained and everything is ten times more blurry than they usually are."
Well, your eyes muscles suddenly have to work a lot more, so maybe that's why you feel this way.
"I feel like my glasses are actually worsening my eyes because this happens every time."
So, if I understand correctly, you changed glasses a few times because your eyesight got worse, and according to you, your eyesight got worse because of the glasses? How do you know that your sight wasn't deteriorating anyways? How do you know there is causation there, and not correlation?
To take an example : if I turn off the light, then slap you, and subsequently claim that the darkness slapped you, I'd be claiming that correlation means causation. Just because you feel like something is true doesn't mean it is.
@@Camustang Oh yeah, I've mentioned this a few times so I forgot to mention that my stepfather saw me squinting at the TV and asked if I needed glasses, and at the time I didn't really care either way so I said sure. I don't remember why I was squinting but I do know that I could see very well. Even if my vision was slightly bad before, my vision was exponentially worse after I left the doctor.
Edit: Also, jesus you're vitriolic. Calm down a bit maybe?
@@skinnymarauder333 To be quite frank, it sounds as if you’re over-exaggerating.
Fun fact: friend as kid had need for temporary correction glasses
Doctor for was so incompetent he gave him bad prescription, instead of correcting his eyesight, it made it worse and permanent.
Now he have to wear really thick glasses to correct that blunder all the time
Lol I lost my eyeglasses recently and I’m telling you guys my vision got better lmao but I still purchased a new glasses cause I don’t wanna get caught driving without my prescription lol
are you near sighted or farsighted
I've always wondered why doctors didn't prescribe eye exercises
or optometrists!
Works if your problem is being crosseyed
“Glasses ruins your eyes”
Me who can’t see without them: okay?
Most people are getting glasses for no good reason. Like just because you failed your eye tesr and the doctor recommends doesnt mean you have to get glasses. Only you should decide if your vision is well and if it realy needs fixing.
CantSayMuch
Actually when you fail your eye exam getting glasses can help not only with seeing stuff but with making sure that the prescription does not get higher much faster. It also stops headaches and other issues that are tied with over straining.
glasses were used to correct my vision while I was a teen... 😐
I feel naked without my glasses on and HATE not having them on outside of my house. I'm glad the myth was debunked.
I got classes about 6 months ago. They are pretty weak as my vision wasn't too bad but I definitely needed classes. What puzzles me is that when I take off my glasses I can't see the things at all that I used to be able to see before I got glasses. Is my vision just naturally getting worse? Am I getting used to glasses and not needing to decipher blurry text?
I think this video is misleading because from personal experience (and relatives' personal experience), glasses do make your vision worse. My vision was a little bit bad when I was a kid...my teacher pressured me into getting glasses and I eventually got them. Now, my vision isn't good at all. I've been reducing the magnification by about .5 or .25 from what I actually need to slow down my loss of vision.
The glasses are making your eyes worse. Please don't listen to this guy. I really would try reduced lenses therapy if I were you.
Spencer poore glasses don't make your eyesight worse. nearsightedness usually do get worse over time, with or without glasses. this is because the eye still grows. even if you wear glasses, at some point, it is likely to stop getting worse.
Spencer poore the reason why you seem to not be able to see things you used to be able to see without glasses might not be because your vision got worse, but because you are comparing it to vision with glasses. the analogy is this: if you watch a youtube video at 360p for a long time, you get used to it. one day you tried 720p and everything gets so much clearer. now, because you're used to 720p, watching 360p seems very unclear. but the 360p now is actually the same as the 360p before you tried 720p. if you stop wearing your glasses for a day, for example, you'll get used to seeing things in a blurry way.
I have kinda the same problem. When I put my glasses on and then take them off, for the next 3 minutes, most things are blurry
Things to consider :
- Nearsightedness increased in the last decades, which is far from enough time to conclude it's caused by genetics.
- There are cases where people corrected their vision only by not wearing glasses, or by wearing glasses not as strong.
- Many people get told that "our sight will stop degrading at X age" (often 25 is used), which seems to be false.
- If there are ANY other factors than genetics, then it means it could be preventable or reversible, and this backhand dismissal of other theories is scentific neglect.
The reason I clicked on this video is because I've noticed that since I started wearing glasses my general eyesight without them has gotten much worse. I did't even go to an optometrist for my eyesight, I went because I had scratched my eye lens months earlier and was still experiencing a weird sensation. But after examining me and finding nothing wrong as far as the scratch goes he handed me a prescription because I kinda do need glasses, mostly for driving at night. So I filled it and started wearing them for night driving. But as I've had them for two years now I've become dependent on them to keep things in focus, even during the day. I can absolutely believe that they make your eyesight worse, at least worse faster that what they would've without the glasses... I'd like to point out that I'm not trying to denigrate glasses. Just that from a subjective perspective I can understand how it's possible for glasses to worsen you unaided eyesight.
Actually you can do exercises to correct your vision. I was told I needed glasses when i was younger. I never got them because I hated wearing them. I learned that most eyes are not too long or too short but the muscles used to focus them are too weak. I dont think this is always true, sometimes the eyes are too out of whack to be corrected by exercise. But if your vision is not too far gone you can correct it without glasses very often.
