So I went to Six Flags on Saturday and spent all day worrying about my glasses. I didn't want to wear them on the roller coastars because I was afraid they'd fly off my face, but I didn't want to put them in my pocket for fear they'd get squashed. I'm wondering what people do on these types of occasions--also sporty folks, do you wear your glasses while you, say, water ski? Do you switch to contacts? Use those horrible croakies from the 80s? Go blind?
