I don't wear contacts. If I did have them, I would never sleep with them in. I think it would make me paranoid haha. I only wear a low prescription because I strain my eyes. I'm a weirdo.
i use to wear my glasses on a regular basis like when i'm on the computer, at school, reading for pleasure, etc. i stopped wearing them often when my eyes were feeling better. i don't think i need a stronger prescription. i do know i just need to wear them when i'm suppose to! lol
