I've always liked having my screen brightness on near minimum - I never have it higher than 4 bars out of 15. I just find it more comfortable not being distracted the brightness of the screen. So the other day my mom was proofreading an essay on my computer. As soon as she saw how low the brightness was, she began yelling at me telling me I would need glasses if I kept the brightness so low, and told me to always put the brightness on maximum (which ironically hurts my eyes way more than having it on minimum). And it's not like a work in a dark environment - I always have the ceiling light and a very bright lamp on my desk on at all times. TL;DR: Mom says that it's bad for my eyes to work with screen brightness on minimum, even though my room is very well lit. So is it really bad for your eyes to work in these conditions?
