Size of frame/lenses

Which size do you need?


Measurements of glasses include the width of the lens, the width of the bridge, and the length of the temple, usually expressed in that order, for example 55-17-135.


Lens Width Bridge Width Temple Length
Measure the widest part of your face. Then measure the bridge and subtract that number from the width of your face. Divide that number in two to get the width of each lens. Measure the bone between your eyes.                                                                             
The simplest way is to measure the arm of an existing pair of glasses. Be sure to follow the bend of the temple and measure the entire length.            

Please note that a millimeter or two in the width of a frame will not make much of a difference, so don’t limit yourself when choosing the style that is right for you.
