I always experience pain in my eyes after just a few hours of working in front of the monitor. Specifically, there is a sharp aching at what feels like the back of my eye, and once I start to feel it I have to lie down and it helps to close the lights and blinds.
What are some things professional programmers do to protect their eyes? I'm a college student and, with my limited time in front of a monitor, this pain already seems pretty intense. I can't imagine what it will be like when I have to stare at a screen from 9-5, M-F.
So, for those who are already dealing with this problem, what are your best solutions? Besides what to do while you're at your desk, are there other things you've found helpful in preparing your eyes for a days work?
