I’m almost never not looking at a screen of some sorts.  I sit at the computer all day long for work and after work I typically play on my ipad for about an hour before I get motivated to go to the gym to watch tv shows or instagram on my ipad for another hour and a half. While I cook I play the TV and /or watch another show or go to the movies. I’m consumed by screen time. If I am not consumed by the computer, my new mac book air, ipad or TV, im clearly looking at my Samsung S4. Somehow I still have managed to maintain perfect vision … i feel it dwindling as my right eye ball is a twitch occasionally
