Computer Eye Strain

I really do not know why I've suddenly been getting a lot of computer eye strain. Eyebright herb was taking care of it for a while, but it seems to have stopped working. The screen looks kind of dark now, and if I open up a window and let lots of light in, there's less eyestrain.

The other day I reset the monitor refresh from 60 hertz to 75 hertz. If you're having computer eyestrain problems, you might want to look into that.
