In reply to episodit:
Welcome to the club!
Glasses and climbing are a bad mix. They fall off, get caught on things, mist up and get water on the inside when it rains so you can't read a map. I'm told that contact lenses are the answer but I'm too much of a wimp to put things into my eyes.
So I struggle. I generally take them off to rock climb. I keep an old pair (the prescription before the current ones) for the hills.
I've also managed to sit on a pair and twist the frame in the confines of a tent.
Map reading in wind driven rain is a nightmare.
