the GP solution puzzles me too. i don't want this to be the solution. i wear glasses and my eyes are already damaged and now i need to filter out the color blue? what about we start making better monitors and screens instead?
That would be great. When they're done replacing every screen in existence, if they could replace all lightbulbs in places people visit during the evening with warmer bulbs (hotels, common spaces, street lights, etc), the lights in all the new car dashboards, everyone's headlights, every cheap piece of electronics that's covered with blue status LEDs...
Or you can just filter out some of the light right in front of your eyes and achieve a workable solution today.
As an added bonus, I think you'll find it actually reduces your eye issues. Tried out the filtering basically because I couldn't think of a reason not to and the first time I put the new glasses on it felt like I'd stopped squinting and relaxed my eyes for the first time in years. I get way fewer eye-strain induced headaches now.
My anecdote: I got glasses this year specifically to counteract astigmatism related to the past 20 years of looking at screens for 8+ hours/day. I was beginning to get headaches every day from working. I didn't even know my eyesight was suffering until someone suggested I go get an exam.
When I saw the blue-light filter option, I jumped at it because I knew I'd be spending most of my time wearing glasses looking at a computer screen anyway.
The blue filter they treat lenses with is very mild, though. It's maybe a 20% reduction. I now wear the glasses all the time even though I don't really need to, and the filter isn't noticeable at all.
