Wait. Computer screens are bad for your eyes?

Looking through infographics yesterday and the things illustrated, I kind of started looking at my life in terms of statistics.  For instance, how many hours I spend awake vs. how many hours I spend (of that time) staring at some sort of screen... tv, computer, phone, etc.

Here's what I figured out : I spend about 17 hours awake everyday, and am pretty much looking at a screen for a solid 16 of those.  Did I mention I had to get stronger glasses recently?
