Already have a frame measurement

To ensure your frames fit perfectly, first determine which size frames are best for you. The best place to start is with the eyeglass measurements on a pair you already own.
First, search for the three little numbers on the inside of the temple arm of your glasses. These three numbers are the frame's measurements.

From left to right, these eyeglass measurements appear in the following order:
1. 55mm - Lens width
2. 17mm - Bridge width
3. 145mm - Temple length
