Pupillary Distance (PD) Guide

How Do You Measure Pupillary Distance?

Pupillary Distance is the distance between your eyes. Some prescriptions have it but some don’t. If it is not on your prescription, this is how you measure it.

Step 1: Print the ruler on at 100% size / actual size. Do not set scale of the printout (i.e. do not choose fit to page option in print settings).

Step 2: Put the ruler on your forehead and stand 8 inches away from the mirror. It is important to keep both eyes open when measuring. If not, have someone measure it for you. 

Step 3: Place the "0" in the middle of 1 pupil and measure the distance to the middle of other pupil. This will give you the distance between your eyes.

The average PD is between 57mm and 65mm.
