About a year ago, my optometrist switched me to daily disposable contacts because I kept getting contact-induced pink eye. I always trust my doctors, so I did what he said. (Back in middle school, I used to sleep in my contacts for weeks at a time, which ruined my eyes. I know, I was pretty stupid.) Now, I know I should probably do what he said, but I'm a college student, money is very tight, and daily contacts are EXPENSIVE. I've been re-using them, which I know is pretty bad, but I don't have money to buy them as often as I should. I know I could just wear glasses, but then I'd have to get new glasses because the ones I have are an old prescription and I can't see very well out of them. Can I switch back to 2-week contacts if I change them as often as I should?
