This node is intended for those of you who use your
monitor a lot. Following these instructions will make it easier on your
eyes.
The first, most important thing is that you
turn your brightness knob down- on most monitors, you can live with less than half
brightness. This makes the refreshes less visible, reduces the
radiation hitting your eyes, and lets you see black-and-white text more easily. The correct setting is not when the whites are as bright as they can get, but rather that the blacks are actually BLACK. The only reason to turn up your brightness is that in games, a higher brightness is an advantage.
Secondly, increase your refresh rate. It's worth it, to an extent, to sacrifice resolution and color depth for refresh rate. Above 85
Hz you've hit the point of diminishing returns, but 85 Hz will be much easier on most people's eyes than 60.
Women seem to be more susceptible to this than
men, but they also have the same problem with
fluorescent lights.
Mount it somewhere dark to reduce glare. Direct sunlight will reduce the
contrast. Preferably you should put it in a room with no windows, and a dim light bulb, but this can be inconvenient. Put it on the small wall as a window, and put dark curtains in front of the window.
Light text on a dark background is frequently easier to read than the inverse. If your OS of choice supports it, make your backgrounds black and your text some bright color.
Resolution is mucho importante. Increase your resolution until the text is no longer easier to read (but not at the great expense of
refresh rate, see above). The more screen space you have, the better.
I hope some of that is helpful.
