I tried to go the contacts route a few years back, I cannot stand touching my eyeball (I freely admit to being utterly neurotic, it is no coincidence my DOG is also neurotic, hah!) I have astigmatism and I am near-sighted. I hate wearing glasses whilst performing sweaty type of activities so when I run (which is not that often lately) I don't WEAR my glasses...once, when I lived in Vancouver, I was running with my dog, when I saw something black and white in a ditch...I said "hi kitty" but my dog started going mental and as I got closer, I realized it was a SKUNK!!! Let's just say I backpedaled in a hurry!

Anyway, my glasses slide down my nose when I'm sweaty, my DH says I just need new ones that are fitted properly (I have an appointment tomorrow, actually.)
