"Although some of these problems may not result in symptoms under less visually demanding conditions, the high demands of computer work cause them to become manifest. "

THIS. After about 7 years of staring at a screen all day at work, then coming home and staring at a screen all night (gaming, programing, etc), plus marijuana = dry squinty eyes-- the cumulative effect was that my eyes began to always focus slowly and unevenly, especially on things far away.

I got glasses and they helped, but it felt like more of a bandaid than a solution.

I have since reduced my close-up computer screen usage dramatically. I also do the occasional eye exercises (youtube has a lot of these and they really help).

I stopped wearing glasses and spend more time outside and away from the screen so my eyes actually have more things to do than look at bright pixels 3 feet away.

If I could give any advice to my younger self it would be to minimize long stretches of staring at the screen. Take plenty of breaks to give your eyes a break.
