I take a break every 30 minutes for about 5 minutes. I want to take better care of my eyes, so I've got an alarm that goes off every 30 minutes and I step away from the computer for a while and just walk around my home, look out the windows, and then come back to my desk and hammer out another 30 minutes. It works for me, and I do not feel as much eye strain or headaches anymore.
