Light emitted by a device should not affect your eye's focusing system. (The lens is on the opposite side of the retina, lest anyone forgot.) There is no research that says backlights hurt vision over the long term. There are only people whose eyes ache and who want to make up reasons for why they're getting old. It's like walking until your legs hurt and thinking, "well, walking was a lot easier when I was young and it must have been all the leg aches that have screwed me up over the years." The same bs about bright lights in the dark has been going around since they first invented movie theaters (yes, seriously).
As opposed to backlights, viewing things close up for a very long time may indeed reduce your ability to see things far away. But putting on your glasses and then moving the monitor 6 feet away is just ignorance of physics. Glasses make all objects float (focus-wise) a few feet from your face. Things that are a few feet from your face become a few inches. If viewing things close up reduces vision, then wearing glasses reduces vision. Period.
Fighting discomfort, not wearing glasses when you can get away with, and doing eye excercises until you're dizzy will indeed make your eyes stronger. Figuring out ways to put your eyes on a pillow definately will not.
i'm sorry guys. it's just people bitching about display devices destroying their vision is one of my pet peeves.
