The issue of "emissions" from computer monitors has been going on for a long time, and probably won't be settled any time soon.. but the kinds of eyestrain symptoms Steve described aren't likely due to any emissions anyway... The biggest problem is the relatively close distance between the monitor and your eyes. It strains the muscles in the eye to keep focussed on a plane at the distance of a typical computer monitor for long periods of time.. (it's a lot easier on the eye when it's focussed at "infinity", or far away...) Add to that the fine detail of a high-resolution screen and the fact that most activity of the eyes is reading text (involving a lot of "start and stop" movement of the eyes, and the parallax adjustments needed to keep both eyes focussed on the same spot), and you get some pretty amazing eyestrain... One thing that can help is to move the monitor as far away from your eyes as is practical... another solution is to obtain special eyeglasses which re-focus the eyes at a much farther "virtual" distance. Ask an optometrist about these... BobR
