To determine your frame size, first look inside your current eyeglass frame and you will find numbers on the bridge or earpiece. If you cannot find your frame size, simply print this page and use our millimeter ruler to measure your frame. Note: There is an acceptable deviation of 2mm in these measurements. Therefore, you do not have to be exact.

If you do not have a millimeter ruler, you can print a very accurate, disposable paper ruler. Simply click here to open the PDF containing a disposable paper ruler, and please disable any "shrink to fit" options on your printer.
