They stop you from getting eye fatigue because they are layered with the natural chemical in your eye that reduces glare from light, it has nothing to do with "yellow light" especially since the light coming from the sun is whitexXSnowyXx said:I've had a pair of gunnar glasses for a few months and they really seem to get the job done. They make the colours warmer so they are easier to focus on (eyes focus on yellow light easiest due to living under the sun for so long) and stop my eyes from getting sore and tired (I've never had that happen while wearing them). They're also supposed to reduce glare and etc however my lair is perfectly darkened so I wouldn't know.
...if only I could remember to wear them every time I'm looking at a screen
