What level of screen brightness is best for eyes?

I am a 20 year old male. I want to know what level of screen brightness is best for eyes?

This is sometimes related to the contrast of the darker print on a brighter background. There is no issue related to having any screen brightness that would affect your eyes in a negative-health way, but "eyestrain" can sometimes be attributed to font size, distance looking at the screen, screen coloration, and prescription issues.
I would always suggest that "lesser is better" and to turn the brightness to the point that you feel comfortable especially over long-term use. This is more related to what your eyes feel comfortable with and certainly, how long you spend looking at a computer screen.
And, if there are prescription issues related to your eyes, not only would the correct prescription be beneficial to use at a computer, but these lenses can be tinted to provide you with the best optical and visual effects, especially for
your professional or personal use on the computer.
Here is a good website that addresses your concerns as well as other issues when using a computer.
