Staring at backlit screens all day has pretty much ruined my vision. I have to lean in pretty close to even read what I'm typing while my MacBook Pro is on my lap (and other text). I sit a few feet away from my 50" TV to play video games (which really is pretty immersive). That should be socially acceptable, but unfortunately most people sit far way so that their TV takes up about 15%-25% of their vision. Backlit displays are usually worse to the average user who doesn't know or care to change a display's backlight from maximum brightness. Anyway, I have glasses for distance, but I never wear them other than when I absolutely need to. I should probably change my habit, but I don't like looking at the world through glass. I'm sure many people on this forum have pretty bad vision from all of the displays they look at daily? Suggestions? Opinions? Our vision is only getting worse. I'll wait a while before having any surgery done since you should only have lasik done once then your vision will worsen again.
