Sizing information: The best way to determine the measurements you need in a new frame is to examine the inside arms on your current frames. On the temple arm you will find three numbers. The first is the lens width, the second is the bridge width, and the third is the temple length. Some frames may list this information on the nose, bridge of the glasses.
