I only have one bad eye. Like, it's terrible. The other one is 20/25, which was good enough that I only wore one contact from 5th grade to college. But then I realized how bad ass I look in glasses. So then I got glasses, and fixed my 20/25 eye even though it's kind of unnecessary.
Anyway, The only advice I have is to get the ones that you only have to take out/put in once a month. If you have to put them in and take them out every day it gets really old, really fast. That's been my experience, anyway.
