I wasn't sure where to place this question, but thought it might be a biological one and went with this folder. So, my parents were having this weird discussion the other day about using my laptop all the time in the dark. They think it's bad and sort of like reading a book in a dim lit room. But, I told them that my laptop as a screen that's lit up and that's different. But they still said it'd probably be bad for my eyes. Would anyone happen to know what the real medical/biological answer to this issue is? Do we need to have good room lighting when staring at our laptops? I spend about three hours a day on mine and sometimes the room is pretty dark.
