What is the right frame size for my face?
If you already have frames you like, then you can match them to a size we have. Frame size information is normally printed on the arms of your glasses, with 3 numbers. First is the lens diameter, then bridge width, and lastly the arm length. The frame size information for each of our styles is next to each image.
Understanding frame measurements:
Maxwell frames // Daylight lens
Frame size: 55-17-145
Size | Lens width | Bridge width | Arm length |

The most important measurement to know
