I wear contacts. if you dont mind the *little* extra weight, just carry a little contact case and a bottle of saline solution. I take my contacts out every night that I can, but sometimes I end up wearing them for days at a time (Yea, I know its bad for you). But having an extra pair of glasses doesnt hurt. I personally hate wearing glasses, so i switched to contacts and love them, they dont really bother me liek they do other people. Having to carry multiple sets for a long time is a pain in the ass though. Also, waking up in the morning with your saline frozen solid with your last pair of contacts inside, and having to put it in your pocket to warm them up while wandering around a town youi dont know, blind as fuck, is not much fun.
