Size Guide

Find the best fitting frame by comparing measurements on a pair of glasses that fit you well with Axon Optics frame measurements.

Most frames have three (3) numbers on the inside of the frame arm:

 These three numbers indicate in millimeters:

  • Lens Width - the lens measured at the widest part of one lens.
  • Bridge Width - measured at the part of the frame that rests on the nose.
  • Temple Length - a measure of the glasses arm that goes behind the ear.

A number that isn't listed on the inside of the frame's temple is the frame width and lens height.

Frame Width

Frame width is not listed as a number on your glasses, but it helps you find the right fit.

A fingertip of space between your face and the frame temple is best. You can measure the frame width (using a ruler or tape measure in millimeters) by measuring from one end of the front of your glasses to the other end.

You may also measure the Frame Width from one temple screw to the other. The screw to screw frame width will better allow you to gauge the space for your face within the frame itself.

These sizes are listed in millimeters on Avulux frame product pages.

Lens Height

You can measure the lens height (using a ruler or tape measure in millimeters) by measuring from the top to the bottom of the longest part of the lens.
