Q&A: What are ideal contrast/brightness settings for minimizing eye strain?

by David Jenyns

Question by Janak P: What are ideal contrast/brightness settings for minimizing eye strain?
I guess the optimum contrast/brightness settings for minimizing eye strain depend on the environment lighting, but are there any general rules, like:
—> Low/High contrast/brightness is better/worse?
—> Particular settings for particular technology (LCD/CRT)?

Thanks!

I’m pretty sure the lower the contrast/brightness is, the less eye strain you will have. Try to keep the brightness on the lowest possible but still bright enough so you can clearly see the content on the screen. So if the surrounding is dark you should keep the brightness low.

Also giving your eyes breaks is a good idea. Such as looking away from the screen for maybe 20 seconds every 10 minutes or so.

Well in general lower lighting settings will help, however the main issue is not lighting in general; If you wear glasses this will affect you constantly because of your eyes attempting to fight through the reflection on your lenses from the light source. If you don’t wear glasses the best way to reduce eye strain is using low brightness settings and be in a well lit room. Though that doesn’t allow the finer details to be seen but it will reduce the strain.
