Same reason I have to wear dailies. And they are expensive AF.Here I am wondering if Ginn can even properly take care of her contact lenses if they're not disposable, and she's talking about also doing Invisalign. I used to have a friend in college who would sleep with her non-disposable contacts and never take them out unless they fell out. I don't know how she's not blind yet. I have to wear daily disposables (one thing I'll totally throw my money at) because my eyes are so sensitive to the protein that builds up even on the 2-week disposables.
