So are yellow glasses completely useless?
-
@herf Because I spend way too much time thinking about things - if you think about it wouldn't green be the ideal tint for daytime usage?
i.e., it'd let in more of the 480 nm long-blue cyan light to keep you awake, more than any other color, while still blocking a lot of light in sunglass usage. And if you're someone who wears yellow lenses for "comfort" or contrast, green lenses should still filter out the dreaded blue light while keeping you awake.
Am I wrong?

@czilla9000 I think color perception is good too, and there are some reasons to think that wider-spectrum light, like you see outdoors, is good for other reasons (vitamin D, retinal rhythms, myopia, etc.)

Vision problems are unfortunately one of the hazards of too much screen time. In fact, the Vision Council found that 70 percent of US adults in one survey reported having some kind of digital eye strain (strained, dry, or red eyes; blurred vision; headaches; back pain; neck pain; or general fatigue) as a result of using digital devices for hours at a time.

during the day you dont actually want to block all blue light from your environment as we need blue light during the day to stimulate wakefulness and hormones with dopamine and serationin . a good quality blue light filter lens needs to filter blue light down by approx 50% especially around the 450nm mark as this is the part of the spectrum that is most damaging! You are right in the many of these clear lens blue light glasses are a scam as they only block 10-20% of blue light and normally only from 400nm-430ish nm, so they dont even filter any at all at the 450nm mark! www.BlockBlueLight.com.au do these computer glasses the remove 50% of blue light across the whole blue light spectrum, so using something like these during the day are perfect!

@ebbs3801 Yeah, they've debunked the blue light thing recently. It's not disruptive to sleep.

@Iron-Arm no this press was way out of line. It answered a very technical question (in mice) and did not at all dispute the contribution of melanopsin, which is responsive to blue-green light. See my notes here:

@Iron-Arm Yes, I also made a reply to this under "new topic" which was suggested. This is a good general principal to keep in mind 1. one study does not 'debunk' a theory 2. Mice/animals are helpful, but still not exactly the same as humans. These mice likely (in fact I'm sure) have spent their entire lives in a lab setting, probably under floursescent light. Their 'baseline" could not be considered the same as ours (hopefully). 3. One must take the quality of the study into account (many blogs (like Science Direct - it sounds "sciencey" , but these are studies interpreted by people who aren't necessarily able to do so. 4. Follow the money. This study was funded by a Biotechnology company. For obvious reasons, they will not want blue light to be a negative thing. (nor EMFs). If you are not aware, trust me (lol, a complete stranger); that a huge problem with the current state of science is that outcomes that are published are controlled by the funding sources - largely pharmaceutical companies and now - big tech.
Hence, we do not hear about the negative effects of things related to all the new technology.

Well the glasses won't make you better at gaming, they'll just block the blue light for the screen to cause less strain on your eyes. As for the brand any should do. Some have more of a yellow tint than others. i would prefer using KLIM Optics Blue Light gaming glasses. It's yellowish tinted glass lens and superior quality TR90 Frame offer supreme protection without compromising style.

Might make you worse at it! Here's a new article - figure 2 says people are better at adding numbers when they see more blue:

yeah, I guess so, they are literally outdated.

Basically, glasses like Gunnar aren't tinted enough to do anything

Thank you for the information. I've been working a lot on the computer lately and my eyes are getting tired, I wanted to try protection glasses. I will try this option.
