I wear glasses, and today, my ipod mini scratched my glasses. The scratch is about 1 cm in length and goes up and down on the right lense. It distorts vision if I am looking directly at the scratch. 1.) I got this pair at Lenscrafters. Is there a way they could fix the scratch? 2.) Also, I had gotten this pair about a year ago. Should I consider getting new ones and an eye exam? 3.) And finally- when does your vision start to stablize? My vision has been getting worse since 2nd grade (I'm entering 11th grade this fall)?
