18 more years :) I probably made my eyesight worse cuz I hated wearing my glasses so I almost never did. I wear my contacts every day but I didn't get those until I was 18.
I tried contacts, but my eyes just felt irritated and dry all the time, so now I just treat glasses like jewlry and get interesting frames. I do still have contacts, but only wear them for scuba diving. I'm pretty blind without the glasses.
