I’ve always had pretty good vision and never had the need for eyeglasses. My grandfather used to constantly loose his glasses somewhere around the house.
My grandmother also wore glasses and she had some kind of special spray lens cleaner that I liked to pour out and replace with water because I am evil like that. But honestly, she got off easy. Considering how mean she was to us, I could think of a million things I would’ve done that were far worse than smudging up her eyeglasses.
