VINTAGE TURA Eyeglasses Frame Mod.686 55-18-135 Japan Gold

The best way to determine what size frame you need is to check the inside arms on your current frames. On the side arm (temple arm) you will find three numbers (for example: 51-17-135). The first is the lens width, the second is the bridge width, and the third is the temple length. All measurements are in millimeters. You may also find this information on the nose, bridge, or inner edge of the eyepiece.
