- Many of us are feeling the strain on our eyes from staring at our smartphones and computer screens all day. But some of Canada's largest optical chains are selling you a solution experts say you don't need: lenses that protect our eyes from the blue light emitted from our devices. Leading experts tell Marketplace some of Canada's top chains seem to be using "misleading" claims to sell the lenses. And an opthalmologist reveals some easy and free tips that will ease digital eye strain.

Of course this comes up in my feed immediately after I bought a pair.
I have one crizal and one normal pair, I honestly prefer the crizal because it doesn't cause the glare.
I did toooo smh
Exactly!! Wtf
Same
They are watching every single step made by you.
Who else blinked voluntarily multiple times after hearing that we are not blinking often enough?
Alexander Nalog I did, after I read your comment
Deni Ahmetaj same LOL
Mind reader !!
Lmaooo
I did!!!🤣🤣🤣
The definition of "Create a problem, sell the solution". They're striking fear in people and using that fear to earn money.
its called eyewashing lol
Like covid

But looking at screens is a massive problem they didn’t create that
Now Please don't go and get mad at the underpaid staff who are sitting at the counters. They're just reading off reading points their manager is feeding them. Direct it to the companies and their rich ceos.

Nope, they chose these shifty job that makes them scammers.
They're "under-paid"?
I worked in a eyeglass store for a couple of years and trust me it's not the sales person's fault . The company brain washes their employees with training. I believed in all that when I worked with glasses.
That's the beauty of it. How better to sell a lie than by training someone to believe it's the truth? When you get a junior, you can scare him with the same tactics that they'll then use to scare the customers, all the while believing that they're helping people.
Well it is kind of your fault for lacking both critical thinking skills and skepticism of authority.
@@nunliski did you know all this information before watching this? Did you know this 5/10 years ago as well? I don't think so. Plus they have a lot of "research and proff" to back up their training so anyone who's taking the training believes it's 100% correct information.
Something that a co-worker said once and I think it's true. Sales people are just the messengers. They have to follow company's protocol 100% or they are let go. So if you want change go after the big ones.
@@philipp3001 Sure. But I'll also criticize tools for being tools. Your entire excuse is that you are too dumb to question your employer. Pathetic. You're a slave.
*That awkward moment when I’m watching this through my blue light filter glasses🤦🏾♂️😭😭*
Do they help? Lol
No bro,don't worry, you can use at night while you're on your pc or phone..because blue effect the pattern of sleep. Because of blue light our eyes pridect that it's still day... and can't sleep suddenly because your eyes pridect that it's day... so don't worry
Mines had blue light coating on for free at Costco, don’t see a difference but lucky didn’t paid extra for it.
@@gustavopolanco6925 They do help. This video isnt up to date. There are studies to look up that everything what the opticians were saying is true. And yes, they do have the resources to know and they do.
Just continue wearing your glasses. You really need to protect your eyes ☺ I'm an optometry student.
Sitting with the optician as they go over all the options, warranties, and add-ons feels just like sitting in the finance office at an automobile dealership. Their #1 job is to transfer as much money from your pocket to theirs.
For real, I just started refusing all the add ons because I hadn't worn glasses in over a decade, it was my first time buying them as an adult, and I didn't want to waste money on stuff that sounded impressive. Then I came back with my tail between my legs because it turns out I really do need the anti-glare coating. Ah, well. At least I saved money on the blue light filter.
I agree, it is a money thing, not a health issue.
No kidding! They’re just like car salespeople, trained to sell every possible thing, more sticker shock with each add-on. 40 pairs of glasses = a nice car (without the add-ons) LOL.
@@jgennickWhat you need is UV filter, always.
i just picked myself up a pair of glasses that block blue light, ultriviolet light, and x-rays, and regular light. my eyes have never been more happy
They block regular light....so in other words, pirate eye patches?
same here. i'm in front of the computer more than 8 hours a day. haven't experienced eye strain since i walked away with a pair of glasses with blue light protection.

Experimental knowledge won't let me believe what this doctor is saying on this video. Most recently I have been having headaches, teary eyes, and my eyes were very sensitive to wind as if a certain lense has been removed from them. I couldn't look at the PC for more than thirty minutes anymore. When my eyes were giving me these issues, I was blinking a lot (anyone would when the eyes are painful) that didn't seem to help. I bought blue light glasses and I am pleased to inform that my eye problems have been removed 100%.
This is something I experienced this week after I watched this video. Blue light lenses are working for me. Blinking and 20-minute breaks in between didn't.
Saving this video for my next eye appointment and they try to sell me "Blue Light Glasses"
When the blue light thing came out first I remember the reasoning was it affects your circadian rhythm. But not damage to the eyes.
Aella Lee your eyes are directly connected to your superchiasmactic nucleus in your brain. The master circadian clock
Yes they mention this at 11:45 in the video!
folks where saying initially that it causes eye strain after long hours of use, in addition to messing with your circadian rhythm. Eye strain of any sort can, if done repeatedly, damage vision in younger folks. Not in the same way that an old tube TV and it's Xray emmissions caused harm, but in the 'read with text too close to your eyes all the time and end up with astigmatism' sort.

Zenni optical
That sounds right.
@@Francisco-Danconia Definitely THIS! Zenni has been a world of difference to my wallet and my style. An entire pair of frames + lenses for $7. It's amazing.
As a migraine sufferer, blue light can really hurt. Yeah, sometimes the sun is just too painful.
you think it's fUnNy?
and those blue light lense block it???bruh
Me too and I'm slightly cross-eyed. IMO, the 20-20 rule is the solution but keep in mind it isn't just for computer screen not blinking for a while. If your eye muscle are strained it is hard to refocus (compensate) after staring at a phone screen for hours in bed at a near focal point. My prescription glasses for my computer work indoors is tinted red for strain and has a prism lens to correct vision. I can only use class 3 polarized sunglasses outside to prevent headaches. This doc talking about the blue light affecting sleep is correct but putting the phone in night mode for sleep is out of his lane and simply bad advice. Sleep psychologist and experts will always say that the the bed is only for sleep and intimacy and when it is time to sleep no electronics and no distractions. Phones, TVs, reading, gambling, etc all keep your mind busy when you should be winding down. IMO, fix your sleep, take a break while you work, and fix your prescription are the best ways to help with headaches and preserve your eye muscles long into the future so you don't need thick glasses to help you see.
I'm also a migraine sufferer, and also have photosensitivity associated with migraine. If you think that blue light is causing pain that other colors don't, that's a mental issue, not a physiological one. I'll be the first to admit that overuse of those baby blue LEDs is obnoxious and aesthetically offensive, but they're not pain-inducing. Brightness is a factor, but not color. Needless to say, you shouldn't look directly at the sun.
So true
There are no concrete studies yet that blue light causes damage to retina or any part of the eye. However, there are many anecdotes from the patients themselves that they feel less tired when using this kind of lens versus ordinary lenses. And patients who had this want to have the same lens because there is "satisfaction" when they wear it. Also, patients who are very sensitive to glare that even AR coat is not enough can benefit with this kind of lens.
Had never heard anything about blue light causing eye damage...only that it can disrupt sleep cycles if you stare at a screen before going to bed.
That was the original study. Sadly companies have to twist this stuff just to maked a buck.

@@dionnaly7186 interesting... not me, but I gotta say that I didn't go to a shopping mall for at least 10 years, if I need something I go directly to where it is without looking around if I don't have to, which is almost all the time when I go buy something/things.. edit: a difference in the way we shop, maybe ???
Telling people this stuff that's wrong should be illegal.
Nirrrina or as I like to call it. “Purpose driven education”. Half the junk I learned as a kid 30 years ago has been disproven or amended. Probably also the reason why children think we are dumb.

Ya gotta be joking, for if you're not, then you're one hell of a LOUSY person to have for a neighbor, which fortunately is not my situation.

She said, you dont need them!
I was glad because i know after 30 years my eyes are still perfect eyehealth
Windows literally has a night "filter" you can turn on so the screen emits less blue light. It just changes the color pallet so there is less blue, but still it's free.
Most Smartphones also have this feature usually called Night light you can set it to automatically turn on after a set time like 6pm. You can find it in Setting>Display
i am a graphic designer and i don't want that haha
Even f.lux works. (I have windows, so i don't know if other OS have it too)
It's free and and you can customise how much blue you want and when. It's really helpful.
@@fawwartz yeah, I once color graded a picture in night mode... But for normal use, night mode is ok, and I get used to it pretty quick.

@@jasenrock Agreed, in hindsight, a simple Google search would have been enough for a definition.
12 minutes to explain that the whole blue light idea isn't to protect the eyes but to help you sleep through normal hours.
Just use the night mode on your devices, it's free
@@OlaviMurto but the led backlight in a screen is still emitting light in the same wavelength regardless of the color of the screen. Backlight is backlight, always on and always cold white (blue wavelengths).
@@antoniojalusic4136 turning the white balance warmer (night light) in software or on the display, then has the same effect as a blue light filtering lens; blocks some of the blue light. With LCD displays the crystals in the pixels block it, in lenses it's probably some sort of polarization.
However in OLED displays the display actually reduces the true emitted blue light, since it doesn't have a backlight at all, but instead each pixel has their own RBG LEDs.
In any case, the emitted blue light doesn't matter, cause the light hitting your retina is the same.
As the video show's, eye strain and degration is caused by other factors. One which wasn't discussed is refresh rate. For some people, low refresh rates cause migranes, but this is easily fixed by using 100Hz and higher displays.
@@antoniojalusic4136 if you open a black blank image is it the same like a blue image ?
You are right in the sense that the blacklight of lcd screens are still emitting but what's displayed is changed so it does help.
@The Great Salad they didn't even mention that it has a negative effect on melatonin excursion the sleeping hormone
This is something eye opening. I always have a query regarding blue light. Appreciate your work for going into details of it . Thank you
You guys are doing a great job exposing these people. Thanks for the help
I've never heard anyone ever claim that that blue light is harmful to eyes, just that it disrupts sleep cycles. Thanks for addressing this in the last 30 seconds of the video lol
I had my phones blue light filter on at night but left it on all the time and it totally made my eyes more tired.
I started to get headaches when I worked on my laptop for long periods, i got some cheep yellow lenses and it helped not sure if it was just placebo.
@@shy8054 perhaps it was just too bright and/or you've stared at it for long period of time without resting your eyes, or it could be placebo effect as you've stated.
@@SayAhh well I was staring at the screens when the glasses where on or off.
Basically the eye protection options in phones decrease the blue light.....trust me i used to have headaches after 2-3 hours of usage.....now it is practically gone...this is similar to antivaxxers type of movement i think
Basically blue light DOES DAMAGE YOUR EYE IN THE LONG RUN...IN SHORT,IT CAUSES HEADACHE AND THAT'S A FACT.....
ALSO MEDICALLY SPEAKING IT CAUSES PTERYGIUM AND THAT'S A FACT
IM A CERTIFIED MEDICAL PRACTITIONER BTW
ssometimes youtube recommendations are really eye opening
Hehe yes
but you also know you should blink often
Let me show you to the door.
Ha eye see what u did there
Eye see what you did there...
Thank you for coming up with this research for all of us who have not yet jumped into this blue light glasses bandwagon!
The reason I buy blue filtering lenses is to ameliorate the impact of late-night blue light when I can't use dark mode; and to reduce glare disability due to acquired visual damage. They work for both of these needs.
Which type of visual damage? If you dont mind telling me
The optician basically advised me against getting it when I got my glasses a couple months ago bc she thinks it's not worth the money and I'm thanking her the next time I go to the place LOL
I got new glasses about two weeks ago which had a blue light (mistakenly). As soon as I got them I didn't like how they had a yellowish tone, as well as the purple reflections they caused. Had them sent back to have the filters removed and I couldn't be happier. Luckily the filter was free (I think there was a promotion), so I just had to stick to my old glasses a little longer while they got them fixed.
Niiice lucky you!!
Good! Patronize that optician more 😊

@@woopsyhazy7300 it is not harmless, but if a tiny little bit of blue light from a screen was significantly harmful, then the sun would have already left us blind.
We are made to resist it.
@@carlosreyesf19 I am not commenting regarding the blue light itself but the premise of the comment which is basically that blue light is present in the sun so it should be fine. Obviously the sun's rays can be harmful so to dismiss someone's concern for a light ray that is present in the sun is not very bright.
This is the most helpful video I have found today. Probably the best video of the day for me.
I used blue light lenses for over five years and it never felt like those lenses were easing the strain on my eyes. Instead, I often got headache and dizziness. Only recently moved back to normal lenses, and the experiences is far better. Don't feel any strain on my eyes anymore and I can see things more clearly.
In my case whenever I turn the "night mode" in my Screen Monitor, it helps me reduce the fatigue tho.
What I mean. If i dont use the Night Mode i can stare at the screen for 5 mins and then the fatigue strikes, If I USE IT i can stare at the screen for much longer without fatigating.

Thanks so much for this info! I really like the 20-20-20 rule! The best thing I found to help with my eyes when looking at my computer screen for hours, is getting another pair of glasses with a computer prescription, meaning focusing on a distance of about 2 feet instead of your normal vision to infinity. In my first year of using these computer prescription glasses, they actually improved my prescription, not made it worse like it always had. Also, my eyes don't feel as tired or strained when using the computer prescription glasses. As for the blue light, I just turn on a setting on my devices to block blue light at dusk.
There's no such thing as a 'computer prescription'. Whatever Rx you need for YOUR use with the screen is not a panacea for everyone and is no different from a "newspaper prescription" (if there were such a thing).
@@karlrschneider A newspaper prescription would be +, and to see a computer screen over half a meter away is a -, learn your prescriptions before you judge

Blue light can mess with our circadian rhythm, but that’s it. In fact, device manufacturers are already adding night mode features that reduce blue light. I thought we got past the eye damage from screens myth years ago. Remember when we found out that television wasn’t really hurting our eyes like Mom said it would?
NinjaTV, I’ve had a similar problem with contacts. It wasn’t anything to do with blue light, but I found out when I went to buy my contacts that my prescription was specifically for an expensive brand of contacts. I didn’t even know they could do that. 🤬 I don’t trust so-called professionals anymore.
I actually leave my phone on night mode all the time now, I don't even notice it anymore.
Even that's nonsense.
@@yogosapphire I'm pretty sure they can't. Tell them to give you your prescription in a cheaper type of lense or you'll report them for mal practice or something.

I got blue light glasses as a gift, and since I spend over 10+ hours on computer, I didn't have headaches and eye discomfort while wearing them, I went a week without them, and as expected XD my eyes were irritated, and sometimes painful headaches, these glasses should be made for people that spend almost their entire day on computer in my opinion, it's not a thing everyone needs. You can just follow the 20/20/20 rule or add a blue light filter(Night mode) which makes your screen a little orange, making it easier for your eyes to see the screen.
Same bro
I just got computer glasses from Gunnar glasses, I'm really liking them so far. They make the computer screen much clearer for some reason.
20-20-20 rule is not exclusively for electronic devices and screens, but for near work (reading, studying, watching details, TV, ...). It has to do with the acomodative system of the eye. When you are focusing near things your eye muscles are working to get the lens more tight. Plus, as you have heard, your blinking rate decreases.
But teoretically this would apply the same for reading a book and for online courses.
Same eye straing and dryness, same eye stress.
You dont fix that with colour filters.

I work at an optical company, and one of the first things they mentioned when introducing the blue light filter to the sales associates was that they only aid in the prevention of digital eyestrain. They do not prevent macular degeneration, as this is a genetic condition that will progress with or without treated lenses, but they do prevent headaches and light sensitivity. If you find yourself suffering from dry eyes and/or headaches after being on a computer for an extended period of time, then the blue light filter is a great option, but it is not a necessary one.
Paige Taylor it does help for migraines 👍 my partner says it has lessened his migraines a bit.
i also work at an optical dispensary and i always mentioned that the blue light filter puts less strain on your eyes. i do not know where the opticians in this video are getting their information from. but CBC doesnt show all the interactions with every employee, they pick the "bad apples" then label the whole industry
Super Andrew 64 that is very true, and of course they only show the bad side, they make money off the shock value.
@@ericahernandez5769 Your partner is experiencing a placebo effect.
@@SuperAndrew64 I work in this industry. One of the major manufacturers marketed a lens coating as Glare Free. Glare is an overabundance of light. These lenses actually allow the lens to transmit more light.
I've also seen lenses sold with Anti-Reflective coating that had no prescription for computer use. People were told they would eliminate the glare from the screen. That is an impossibility.
Sometimes the people that bought them truly believed that the lenses helped.
Caveat Emptor - I don't trust any extraordinary claims.

One thing they fail to address is that too much blue light exposure can cause issues with your sleep cycle, which is a good reason to buy the lenses. However it’s actual impact on your eyes is negligible.

ig they didn't sell very well so they started to push these talking points to scare customers
rafisofyan again, that’s required only if you are using your phones at night. And if you are so concerned about light from phone keeping you awake, your tube lights also have similar effect. Basically when you have artificial lights or the backlight from your device around, your brain perceives it as daytime and tries to keep you awake.
1234 12345 abc i hear you, you should do your research, but these are the people that are supposed to help you maintain your health. if not them then who are you to trust? it's not informing if they give you "information" that can't be backed up. Me lying to you isn't informing you, it's just that: lying.
In Australia it doesn't cost too much to add blue light filters to your glasses. The main reason it is recommended is for reducing the blue light effects on melatonin production, and therefore to help you sleep if you use a computer, ipad etc. before bed. The general glasses stores/optometrists would only say blue light from screens causes eye damage in sustained and extreme cases of staring at a screen. Not sure what the deal is elsewhere in the world.
I just turn down the brightness according to the environment I'm in and at night I use night mode which reduces the blue light emitted by the screen and fall asleep 2 minutes after looking at my screens and I don't have eye strain very often

Sales boss must have been clueless too. Probably concocted by R&D and pass on to Marketing.
@@ThreeFontStreet Between starving and homelessness, and shoveling marketing BS, sure, they 100% freely chose the later.
@@grandsome1 - Good point. When I used to actually answer telemarketing calls, I would tell the person that I am sincerely sorry they have to do that job and wish them better luck in the future. Then I ask them to not ever call me again.

@@TheNobleFive You think those people don't try to? (when they're not exhausted by their entry-level job, that is.)
People love to blame the poor, but when bad luck hits them, oh, they're no longer personally responsible for their sorry state.
What you have is always at least 50% due to luck, and the rest to hard work and your grit.
That's because the world is either random or subject to a capricious deity, which is why that the meritocracy is an illusion.
My Samsung comes with a Blue light filter.
Definitely a noticeable difference in "hue" and relaxing to the eye, but not sure about all the other claims.
My LG has this feature too. the only difference I notice is with filter on, I pass out when I'm trying to play video games. I turn this off if I plan on grinding late into the night 🤣
@@Mattvweiss that means the filter works as intended XD
Matthew Weiss which means that the blue light has been blocking your melatonin your sleep hormone so the filter is working as intended.
Yeah that’s the primary thing I’ve heard, and experienced for that matter; the color warmth of the screens you use before sleeping has an effect on your ability to fall asleep. F.lux is a good program to fix that for PC as well.
I believe one of the only claims that is legit about blue light is that it can mess with your circadian rhythm. In other words, we are meant to get tired when we see less light around us, and when you constantly see blue light, it tricks your brain into feeling more awake.
I started blinking voluntarily multiple times after hearing that we are not blinking often enough.
Blue light filtering glasses from Warby Parker cut the eye fatigue I felt for looking at large monitors for 12 hours a day by 80%-90%...maybe it's not harmful, but the glasses made a significant difference...and I still can catch myself staring wide-eyed with the glasses on. It's worth it to me just to have my eyes feel better. It's amazing how even doctors talk like they know better in all situations, even if they have no real personal experience.
Same. A lot less eye strain with the blue light film on my glasses.
Lmao who else has the blue filter glasses on right now 😂😂💀
jake me 😅
Lol i do but i only paid like 50 bucks USD in Vietnam. I liked them so much that i had a second pair made on my next visit.
Adding the filter to the lens was free for me, so eh 💁🏼♂️
They feel comfortable! Mine was $15 to add on
well I just want to maximize my claim, picking every option I can get
How come I'm finding out that it is not worth it literally a day after I paid for one of those. *Cries in blue light deception*
I seriously just picked up my new glasses yesterday, naturally I paid for it.
I havent watched the video fully yet but I thought that my glasses with the filter on were the best investment I made the last couple years. I fall asleep almost instant even tho I just sat in front of the computer 5 minutes ago.
@@FFriday you coul've used "night mode" which everything has nowdays.
@@MrGenius2 I did but the glasses are better since I dont like that yellow filter on my screen when i am watching a movie or playing the game.
@@FFriday wait what do you mean, it should have yellow, since it removes blue. White HAS blue on it, its impossible to have white without blue
I can honestly say after working 5 months straight in front of a computer I started to get headaches and my eyes felt fatigue. I got a $50 pair and it really has made a difference. I've never worn glasses in my life before so I was able to tell the difference
@The Lucky Pasta or the person couldnt see that well to start with, and getting glasses made it less blurry, hence less headache inducing.
At least that's how it went on for me.
I had headaches while working on the computer and after getting prescription glasses without any of these blue light filters, the headaches went away.
@The Lucky Pasta my bad I wanted to say "without any blue light filters".
@@vator_rs why
Same
Thank You Thank You Thank You. My goodness, can't thank you enough for doing this investigation!!!
In Australia, Specsavers, the largest glasses company in the country literally says on their website that Blue light is not data proven and the glasses are not data proven to help aswell as them saying in plain language that extreme circumstances cause blue light damage. They also have a list of stuff you can do to help your eyes instead of buying blue light. This is actually amazing to see that they care more about spreading truth rather then selling
I'm surprised I finally found a company that doesn't try to scam people under a monopoly.
After reading what you wrote, it literally sounds like they have a big enough Monopoly to scam you but they decide not to.
I'm actually amazed.
@@REAL-UNKNOWN-SHINOBIthat's the American way though isn't it? Pure and simple capitalism, like th doc said - They want to sell you something? They're going to make you scared enough to want it. Oldest trick in the book 🤓
Specsavers even lists it as a free additional sometimes gotta respect that
Dammit. I wish I watch this before buying my new glasses. I feel like I was scammed. Bummer.
because you were.
and they got away with it.
oh, i meant bummer.
They also suck for photos.
Well at least my eyes feels less strain
Me too, even the eye specialist never told me that.
But somehow while gaming for say 4 hrs i prefer the time i have my glasses on rather than not.
WOW! I'm going to get my eye exam now. Glad I found this! It always comes down to diet when it comes prevention, no matter what it is.
This is the best channel! quite informative...
Then they get mad when I say “constantly straining your eyes is what does damage, not some weak light.”
Props to CBC, I really appreciate how well this was put together. Go out and see what sort of claims salespeople are making, then have an expert evaluate those claims. I wish there were more pieces like this for other misleading claims companies make in order to make a sale.
I agree, rather than confronting and causing a scene for the sake of show. This is a lot more "here's what they say, here's what the experts say, you decide.". Makes me more inclined to listen and believe it.
Wouldn't it be lovely if every story they put out had to be like this. Just think how different everything would be from science to climate change to politics.
Thank you a lot for all this clarification.
I have been looking at screens, probably half a day, everyday, since I was 5 years old. I still have 20/10 vision...
I like to wear my blue light glasses when my eyes are already fatigued from allergies, especially at night!
The Bay Optical is so bad that I will not go back there.
Wow! That's pretty bad!!
crosswire7777 lol
Why? What happened? Is it customer service? Or are the frames easily broken?
@@angel_cat The frames were junk and the lenses would pop out. In fact, I had to get a tiny screw driver and learn to put the lenses back in myself. When I got new glasses I tossed the Bay Optical frames into the bin; they didn't go to the Salvation Army; I didn't want anyone else fighting with those frames.
“Fatigueness” isn’t even a word.
'fatigue' it is ..in french... tiredness was too mainstream i guess
Who would put a thumbs down on this video? Makes no sense. This was a great report.
i bought blue light glasses (no prescription, i have perfect vision) because i have a migraine disorder and it helps with that and insomnia and ive never heard of it being for eye strain. they genuinely help me a lot and i think maybe the eye doctors/glasses sellers in this video are profiting on a misunderstanding
Eye strain is what causes the migraine
@@smitdizz420 no blue light causes migraines because it affects your brain chemicals
@Tom S. A lot of people with migraines have light sensitivity. Light is one of the triggers.
@Tom S. Eyestrain is also cause by astigmatism, which is extremely common, the astigmatism lense reduces the glare. Glare makes your eyes strain leading to eye fatigue or migraines. The best prescription combo is astigmatism, blue light and regular lenses (if you need them). My eyes feel less tired from when I didn't have glasses
@@Stacy-WereAlso, migraines can be caused by prismatic effect of the lenses. I have one patient that mentioned his migraines improved by using the correct OC height in the frame. It is also why PD is important.
I (USED) to work at a glasses store and they always told us that we were not allowed to say BLF is clinically proven to do anything, and we were advised to tell customers that it is not a medical aid in any way but just an add on that you can have. Not all glasses stores are evil, find the genuine ones! I no longer work there, but Bailey Nelson was a very positive honest, and *relatively* cheaper glasses store.
Oh wow small world, same! I work there now~
you make a good point.
“This is what people deserve if they’re too lazy to do their own research.” Or... Maybe people shouldn’t have to doubt what the people at the eye doctor’s office tell them. I go there to get a professional to help me see and educate me on my eyes but what we have here is a racket of lies to increase sales numbers.
Definitely. People can't be expected to be an expert in every single field, we pay other people to provide us that service and there should be laws and regulations to ensure they continue to act within our best interests.
Or people shouldn't be getting their examinations done at the same place they get their lenses and frames. Go to an external optometrist for the prescription, then shop for frames elsewhere. Those places with in house examinations are made to make things convenient for customers while also limiting consumer access to reliable information by way of convenience. Why take the extra time to get a better price when you get it all done in one sitting and risk getting ripped off?
@@kelvintam9323 or we can just have regulations to stop stores from being able to get away with completely ripping off customers by lying to them.
It's usually not the optometrist that's giving this false information. It's the sales reps on the floor that work on commission. And you can't even really fault them, as the Dr. said they're just given talking points & these flyers. Most people who work in sales can recite the information their given to sell the product, but often don't know what it means.
@@knightwolf1872 ok, but someone must be feeding them this information to recite.
Someone is to blame, and there should be punishment for this blatant false advertising.
Very informative and helpful. Thank you.😇
The question is formulated incorrectly. The correct form is: Are blue light blocking glasses useful? And for some they are. Because they help to fall asleep on time and sleep better, if you use them a few hours before going to bed. Research shows that bad sleep affects memory, cognitive abilities and may take a few years from a human life. And I feel relief when I put them on at 6 pm in public places with fluorescent light.
“Not blinking as often causes the eye to dry out...”
*EXCESSIVE BLINKING INTENSIFIES*
I have blue light filtering lenses on my glasses, but I don't believe that blue light is damaging to the eyes. Being prone to headaches/migraines and having an office job, I have found the new lenses help "dim" the background light of computer screens and has helped prevent or ease off headaches. I wouldn't discredit the lenses completely, I think they can be helpful in some instances.
blue light filtering glasses definitely helps to reduce the glaring brightness from screen, to test on android you can use night mode, for pc use software flux or windows 10 comes default with night mode. Anyone who has a job of sitting in-front of pc staring white background pdf docs can attest to this. At work where I cannot control night mode settings I have to use my glasses. Why else 'dark mode' on apps and sites are becoming more popular, it saves battery and is relaxing for your eyes.
Same. My eye twitching stopped after using blue light lenses.
@@vikasp5161 There's an easy to use brightness setting on Android screens.
...placebo effect...
Blue light isn't harmful in and of itself
It's when you're working weird shifts, using screens at night, etc. Where the blue light can mess up your circadian rhythm.
Aside from that, theres really no benefit
Back then, Companies were thinking.. People with eye disorder are buying glasses, but what about others.
Now, problem solved " Blue Light "
I have used with blue light filter and without Blue light filter glasses personally i felt the one with the filter gives much comfortable while working on computer for many hours
I just bought one today. Got recommended this now. Not once did I google or search for glasses. Coincidence 😟?..?
Your number from card / Bank transaction, maybe used by Google and lead you here
Sahil Sharma i have an eye appointment tomorrow and this got recommended to me. i didnt google anything either 😪

Went to a couple eye glasses stores last night.... then this
Not gonna lie but I felt a difference after I start using them. I used to get headaches after I use laptop and my phone but ever since I bought a blue light filter specs, those headaches were gone.
Placebo
the problem wasnt blue light, your previous lens were most probably the wrong dioptors leading to the eye strain.
Same happened to me. My prescription rarely changes, I'd get migraines daily, being on the pc and phone all day, I can tell the difference as well. Plus I sleep a whole lot better at night too
@@aceyourgame9414 eh, its okay, if it makes him feel better it makes him feel better
Thats bogus thats obvious your power must have increased leading to headaches honestly i do have blue fliter but still using phone for a long times does cause eye strain
Been on the computer almost 10-14h per day for the last 14 years.
I'm still good but indeed I have fatigue on the computer screen. But I started looking away a few minutes every hours and it's SO MUCH better.
I don't know but I can feel the difference when I had non-blue light lenses and now that I've been using them. No more eye strain for me. From experience, I can tell how blue light could irritate the eyes. I used to watch Netflix or CZcams videos for hours on my cell phone with the lights off and no glasses on. When I woke up the next day, I felt a tingling sensation in my eyes. Just ignored it and continued with the habit until maybe days after I drove to the office with this feeling of having sands in my eyes. My eyes were watery, and I had a hard time opening them. I would squint all the time. Since then, I stopped the habit and never had this eye irritation again.
Personally, anti blue light glasses helped me on my eye strain problems that causes headaches and affecting my overall health. Still, one day break from digital screens is still the best.
l also want to buy them coz l use the computer to study and the headaches l get eyy
@@stanleymutinha4281 headaches
Actually they could help people with light sensitivity because it might not be an eye problem but it could be caused of a neurological problem.
They wouldn't help with that, but they may have made you more aware of the effect of staring at screens all day.
Like did you know that you don't blink as much when looking at a screen.
Same!!!!!
I thought it just messed with your sleep cycles.

Try getting bright light in the morning it will make you more tired at night.
Nah man, all that blue light causes your retinas to detach.
@@benjidaniel5595 our sun emits blue light too, more then our electronics
