Glare filter for reading?

Question

I get headaches when I read on a computer. If I read a book I have no problem. Will installing a glare filter on my monitor solve this problem? If not what will?

Answer 1

It will certainly help. They make a more expensive filter just for that reason. It really protects the eyes and stops headaches ! It will have a yellowish( amber ) tint

Answer 2

Maybe.

If you have a lot of reflections from the screen a glare filter can help. If not, just turn down the brightness and contrast to a comfortable level.

CRTs turn down the contrast first, LCDs turn down the brightness first.

If you have a CRT make sure that the refresh rate is at least 75 Hz. A 60 Hz refresh rate will cause the screen to flicker and that will give you a headache. If you are particularly susceptible to flicker then a refresh rate of 85 Hz may be needed. Almost everyone sees flicker at 60 Hz, about 2% of the population can see it at 75 Hz.

To check or change your refresh rate:

Control panel > Display Properties > Settings Tab > Advanced button > Monitor tab, The refresh rate is in the middle of the window. If you can not get it above 60 Hz you may need to drop your screen resolution, depending on the CRT monitor's capabilities.

LCD monitors do not suffer from flicker the way CRT monitors do. All LCD monitors should have a refresh rate of 60 Hz.

People stare more at a monitor more than they do a book. Make sure you look away every few minutes. Close your eyes for a second or two. Sit back and stretch your neck and shoulders. Once an hour or so get up and move around.
