Irrationally phobic, or reasonably concerned about something you haven't experienced? In other words, could you get used to it if you started doing it?I'm phobic about contact lenses, so that would probably be a deal-breaker . . . .
Personally, I wear glasses and HATE the idea of sticking something in my eye like that, but given that I know so many other people who do it, I think I could get used to it if I had to.
