Do blue light glasses prevent eye strain? #shorts #science #SciShow

Comment reminding you to blink

Also turning down the brightness on the screen helps a lot. People have their brightness up WAY too high. I have mine down lower than most people I know and I have been having a better time on my phone or computer. Also dark mode has been an absolute god send Edit: SOME OF YOU GUYS NEED TO GET YOUR EYES CHECKED

Our supervisor in the call center suggested that after every call, after finishing the paperwork, we should close our eyes and count to 30 before taking the next call. It definitely helped with stress and eye strain.

Oh thank you. I do some design as part of my job and need blue to make sure the colors are working. My dad told me to get some blue lenses and "they wouldn't impact my ability to see blue." I told him if you can still see blue the same with the glasses as without, they're probably not filtering out anything. Cause, you know, that's kind of how light works.

Just a heads up for whoever does not know. most doctors suggest the 20 20 20 rule. Look 20 feet away for 20 sec every 20 min. this helped a lot more than my blue blocking glasses. Not saying that they do not help at all but more because the raise the contrast of text making it easier to look at. Also use dark mode with black backgrounds with white text.

I didn't realize people felt blue light had an effect on eye strain. It is not for eye strain, but rather your circadian rhythm. Blue light tricks your brain into thinking it is day, so blue light from your screen late at night can upset your circadian rhythm. Blue light filters late in the evening may make it easier to fall asleep at night.

Using blue light filters actually helped a lot with chronic migraines for me. Not sure if it was a placebo effect or not. But when I turn the light filters off on my screens they tend to hurt my eyes now.

I genuinely experience physical eye relief when I put my phone screen on warm mode

I have my phone set to turn on a blue light filter at 9pm, and if for whatever reason it turns off, or I turn off the lights earlier, I feel like I can't even look at my phone! No idea if it actually helps with sleep/circadian rhythm, but I definitely prefer to have it on at night regardless.

I was having eye strain and dry eye problems several years ago. At the time, I was doing a fair amount of screen work. An ophthalmologist suggested that I was getting to the age where presbyopia was setting in, and though my distant vision was pretty good, I needed reading glasses, or prescription trifocals. He said that I was probably compensating for poor focus by squinting and that suppressed blinking, which leads to dry eye because blinking squeezes out tears and spreads them on the eyeball. So I got relatively weak reading glasses, right for screen distance, and my eyestrain and dryness cleared right up. Later, I got prescription trifocals. Those were great. The middle segment was just right for the screen.

While I will still get eye strain, I absolutely do use blue light blocking glasses to help prevent pain and migraines.

I got a blue light blocking coating on my prescription glasses and after wearing them for 2 years it honestly hurts if I take them off and try to perceive the full spectrum of light. Like if I put in contacts and walk in sunlight or look at a computer, it hurts a lot more than it should.

I provide IT support for a bunch of vision scientists. When "blue blocker" monitors first hit the market I asked one what he thought, and he said it didn't make much sense to him. Glad to know he was right

I was getting bad headaches and visual disturbances in my field of view (to the point of not being able to drive for about 1/2 hour after extended screen time). I bought blue-blocking glasses at Walmart and it has completely stopped those effects. If I lazily forget to put them on I am reminded after a couple hours as the problems return. For me, those glasses definitely do work.

Blue light is only problematic when you’re trying to go to sleep because it inhibits melatonin production. It triggers wakefulness. In my experience, eye strain is caused by focusing on things that are too small, too bright, too dark, and/or not in great focus. I have terrible myopia and irregular (uncorrectable) astigmatism, so eye strain due to poor focus is very common. I also notice my corrective lenses shrink things quite a bit, making me even more prone to eye strain. For me, just scaling up the text, adjusting or removing my glasses, and making sure I don’t have to squint make my eyes less tired. Oh, and I have to remember to blink.

The placebo effect is a powerful thing

The eye strain isn't because of the blue light, it comes from staring at a fixed focal distance for ages. The blue light just keeps you awake.

The other issue with screens is you never have to change focus and so your eyes are at the same focus for too long

My head gets less tired if I use blue light blockers, like on my phone. I'm ND, and can be very sensitive to light. Most often to the bright white/blue lights. So a blue light filter really helps me, because otherwise I'll get migraines and my eyes will be hurting. So at least it can be helpful with those issues! 😊

Reading glasses can help because they reduce the effort your eye muscles require to focus on close objects. Basically the glasses shift your focus closer so your eyes don’t have to. They also magnify the image by about 15%.
