I have really great eyesight, I don't need glasses. What about you?
You are lucky. I have horrible eyesight! I wear corrective eyeglasses, but I'd like to get contact lenses. 
Oh no, well that's not too bad. Why don't you have contact lenses now?
I used to when I was younger, but they were just so expensive. Most contact lens wearers are females around my age.
