The relaxing of the eyes is all depending upon the refresh rate. As for the constnt flicker, you had a low quality moniter. Im using a CRT at 60hrz, and i dont see any flicker what so ever. And it doesnt hurt the eyes. But what really relaxes the eyes is a Red, blue or green amient light behind any computer moniter, or tv. It almost makes you see it clearer.. Not sure why it does that, its just what helps relax the eyes.
