Where can I find my frame's measurements?
On each product page, the frame measurements are listed as three numbers. The first number refers to the width of one lens in millimeters, the second number to the width of the bridge, and the third to the length of one of the temple arms.
For example : 48-16-130 means 48mm lens, 16mm bridge, 130mm temple arms
Most glasses (including all Jonas Paul Eyewear frames) have these numbers printed on the inside of the temple arm as well.
