I do, since I'm like 15 or something. The hardest part is the beginning, it's difficult to touch your eye at first! You feel like you'll die. DO NOT eat spicy food before taking them off if you're at home, take them off before. Otherwise, when you get them off probably won't hurt as bad as the next day when you put them on!
Do not sleep with them. I do not, but sometimes sleep wins over and nothing happens. Chronic use during sleep can be really bad, though.
Good luck
