Blue light from computer screens and smartphones stimulates eyes and can cause sleep problems — but a new analysis finds blue light blocking glasses may not be much help.

    I don’t know about glasses but the various Night Mode applications help my eyes a lot at night. I use a soft white bulb (4200k) and match my screens to the same temp and I have noticed much less eye strain/pain. Whether that helps sleep or not I have no idea, but it’s certainly more comfortable on my 4k tv/monitor that wants to blast 800 nits into my face at 11:00pm. I use an application called Iris on both macOS (when connected to the tv) and Linux (always connected to the tv) to adjust the color temp and also the brightness because this tv simply doesn’t get dark enough on it’s own without messing with color or contrast. You can offset the reddish hue by increasing the green tint, which is a color that doesn’t mess with your eyes or ruin your night vision.

      I agree. It does something for me.

      The bigger thing in my case is just not using dopamine apps like social media within 2 hours of bedtime.

      I got night mode on all screen devices and it completely fixed my sleep issues. I used to take an hour at least to fall asleep, now it’s like 15min. Also, during holidays I do not push my sleep cycle to 5am anymore.

    The most recent time I went to get glasses, I asked about blue light frames and the guy stopped me and said something along the lines of, “Don’t bother, they’re actually bs unless you get the ones with super yellow lenses - those are legit. Or use computer programs to make your screen orange, that can also help. Folks just wanted to find a way to charge more for glasses, and it’s been twisted so you actually sound more informed for getting blue light coatings. You’ll notice that I didn’t mention blue light or even pitch it to you - you brought it up on your own.”

    Thought that was kind of fascinating and kinda cool of the salesman to talk me out of spending more money.

    This is similar to the claim that using a UV-filter will prevent fading of artworks. While high energy invisible ultraviolet light can be damaging, and visible light in the blue part of the spectrum can also cause damage, and normal clear acrylic is already a fairly good UV filter.

    If you really want to stop the effects of blue light, you would need a strong yellow filter. If you can see blue through the glasses, they’re not blocking blue light.

    Edit: lowering light levels does more than filtering anyway.

      Placebo effect is a thing though. You sure its not just screen settings that make a difference?

    Well I prefer to dim the screen for night instead of just screw up colors with low blue… It definitely helps me with getting sleepy easier.

      This research only says that the glasses are probably unhelpful. As far as I know it’s still accepted that blue light is stimulating and can mess with sleep, cause headaches, etc.

        Well, light bounces around. Its… bound to get in the eyes from elsewhere that just a straight line…

      It’s not tho? The article was able the glasses, not the blue light thing in general.

      Oh I forgot. it’s the internet where people only react to the headlines.

      I knew it wasn’t bullshit as it does help your sleep pattern because of your body is response to light temperatures for your circadian rhythm, but I would roll my eyes when people thought it would help with eye strain etc
