I have lost my prescription the doctor gave to me, and now i need get new glasses. Can i buy new eyeglasses just by giving my current lenses for them to copy?

Of course you can. But you should go to a big chain store at the mall, like Pearlevision or Lenscrafters. The staff there will use a special machine called a refractometer to read prescription off your current lenses and then make you a copy. Then you can get your new eyeglasses according to the prescription of your current lenses.

Maybe. Some of the small glasses stores are unable to copy the prescription from your current lenses. You may take your current lenses to some big chain stores where they will use special machine to read the prescription from your current lenses and then they will have your new glasses made according to the prescription. If you can't find a big chain store in your local place, you's better have an eye exam again at any optical store to get your prescription.
