Hey everyone. I have something off-topic I'd like to ask. Do any of you get headaches when working for long hours in front of the computer? I find that when I am hard at work and concentrating to my work on the screen, I get a headache after about two hours of work. However, when I just casually use the computer for either games, surfing the web, reading Techspot, or listening to music, then I can usually go up to about 3 hours without any discomfort. I was just editing a movie for a school project, and I was captivated and 100% hard at work, while staring at the screen for about two hours straight, at which point I realized my headache. Does anyone else experience this? Is it natural to feel stress in the form of headaches when hard-at-work on a computer for a long time? I know there are many of you who work on computers for a living, how do you manage any eye strain or headaches from that? How often should one take a 5-minute break when working on the computer? Thanks.
