I have seen my sister using them for years, i don't think i'm disciplined enough for them though, you know, don't sleep when wearing them, wash your hands before using them, change them every once in a while, too much

What?

I only know many kids/teenagers love to wear glasses to feel like grownups. My mom always wanted to wear them when she was a teenager so she faked having eyesight problems but the doctor realized she was lying (because she pretended she couldn't see even the biggest signs) and told her he had to remove her eyes altogether, so my mom had to suddenly get her eyesight back
