i dont really know where else to post this problem, yahoo answers never helps, and i dont know any other forums with many knowledgable people that likely use computers too much. anyway, heres my question: basically, can looking at lcds in certain conditions mess around with your eyes? after looking at the retina display on both the ipod 4g and the iphone 4 for a long time, like while watching video, or playing games, i have noticed that my far-away vision is blurry for a while after. this does not happen when looking at other, lower pixel density screens like ds's and older iphones, and computers. has anybody else experienced this? could the "retina display" ironically be destroying my retinas? the other thing was that i feel like i have to strain my eyes to look at a laptop screen when its dark. should i turn down the brightness? or turn on a lamp to light up the room? i have heard its bad to look at a screen in the dark. does anybody else have any experience with this? i figure others on here might have experience with similar situations, and their help would be much appreciated! thanks!
