First time wearing glasses, what to watch out for? (no pun intended!)

[MrBounce]

Don't play racket sports in them unless you have the elasticated strap thingy to hold them on. Playing badminton then watching your (now out-of-focus) glasses go flying across the court is both irritating and potentially expensive...

Well I personally worse glasses for about 1 day if that then ditched them in favour of contacts. Over 10 years later I still don't own a pair of glasses.

Couldn't deal with stuff like, they steam up, you have to move your head more, blurry peripheral vision where the glasses end, making your nose itch like a bastard etc etc etc....
