Why you don't need blue light lenses: Hidden camera investigation (Marketplace)

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.

This is the most helpful video I have found today. Probably the best video of the day for me.

[@RayRay-fd3st]

As a New Jersey licensed optician for 50 years I can tell you none of this blue light blocking has much merit. I have endlessly researched blue light effect on circadian rhythm on the eye and I can tell you the studies are flawed.The blue light in the light spectrum( red,orange,yellow,green,blue,indigo,violet) is essential to our wellbeing. It’s the light spectrum that tells our body it’s day time. To block any portion of blue light all the time your wearing your glasses may not be beneficial to your wellbeing. I believe the only benefit to blocking blue light would be in overcast or night time vision. Blocking blue light does give the eye better contrast in those conditions but only those conditions. Thus any lens with a yellow tint will effectively block blue light, which is the most vibrating annoying of the light spectrum,but you wouldn’t want to wear yellow lenses all the time. If you want to block blue light just order a clip on that fits over you eyeglasses. Optical establishments will push blue blocking coatings for the simple reason to add on to your eyewear. The only coating that all glasses should have is anti reflective coatings.

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.

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.

@@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.

[@vorpal120]

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.

[@StringerNews1]

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.

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.

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

@@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.

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.

[@johanliebert3609]

[@Fighter4Street]

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.

[@MarceloArzubialdeRodriguez]

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.

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.

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.

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 KZbin 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.
