Those numbers are the lens width, the bridge width, and the temple arm length in that order. And the measurements are always given in millimeters. So, in the example of our Larkin frames, the lens width is 51 mm, the bridge width is 17 mm, and the temple length is 140 mm.
What does 53 17 140 mean on glasses?
The higher the number in diopters, the higher the strength. So, +1.25 reading glasses would be less strong than +1.50 reading glasses, which would be less strong than +1.75 reading glasses.
What are the numbers on a pair of glasses?
Youll find up to three numbers on glasses frames, and they stand for the lens width, bridge width, and temple length. These numbers are written on the inside of one arm and may be separated by spaces or dashes.
