Fitting Guide

If you currently wear glasses you can find the size on the inside of the temple or inside the bridge.

The measurement is usually written like this temple below: 45-22-145

 

• The first number is the eye size (width of the lenses in millimeters)
• The second is the bridge size (distance between the lenses in millimeters)
• The third is the temple length in millimeters. 

    

                             

How to measure your PD

The Pupillary Distance or “PD”  measures the distance between your pupils, measured in millimeters. This guarantees the optical center of your prescription lenses is in the correct spot. 

Your prescription may have your PD already listed. If not, use your friend or a mirror to help you take the measurement.

When you wish to measure this yourself, the guide below will arm you with simple, step-by-step instructions to measure your PD at home.

In the example image above, the PD measured 59. Here is how that was determined:

1. Stand approximately 10 inches from the mirror.
2. Holding your head straight and still, place the millimeter ruler against your brow.
3. With your right eye closed, line up the ZERO mark with your left pupil.
4. With the ruler on your brow, next close only your left eye and read where your right pupil lines up.  
5. This is your PD.

Measure 3-4 times for accuracy and simply use the average. A typical range for children is 43-53, and for adults it is 54-74.
