i didn't know he uses powered glasses
blue blocker glasses are useless as there has been no conclusive study that indicates that blue light exposure leads to eyesight deterioration and the whole market is made up on a lie !
what actually works if i just wanna protect my eyes from damage as im exposed to screen all day
nothing really, just make sure to exercise it and the focusing muscles too. but aside from getting eye test and retina check often there isnt anything you can do. thats because screens dont harm your eye more than anything else (except for focusing only on one distance for a long time and drying if youre too locked in)
thats the problem, 5-6 hours on screen at work, 2-3 for studies then even my entertainment is from screens
i mean your right except that blue light glasses often are based on computer glasses to reduce glare which IS real, so while blue light glasses dont do anything against blue light (as far as we know) they do the job of computer glasses in most cases, but afaik they usually both just cost the same, so you can just buy blue light glasses and on the off chance there is some correlation we havent found yet it works for that as well
nah blue light just causes discomfort which is temporary, it also affects your sleep as blue light suppresses melatonin production
