Yes... this is a big problem. My eyesight has deteriorated significantly from working long hours in front of a computer. There are many things I could have done better though to help lessen this:
- Blink often and use eyedrops to keep your eyes moist
- Look away from the computer every so often and focus on something in the distance
- Be careful not to stare too much at the screen
I'm sure there are many more...
