I wonder if so many people wear glasses because of computer and television screens? I mean it can't be good or natural for your eyes to stare at them as much as we do, and when I was a kid my eyes hurt so bad all the time, till I found out it was because of my TV addiction and it got better when I stopped looking at any screens. Thankfully, I don't watch any t.v. beyond my morning news and some new episodes of family guy, simpsons, american dad, and House.
