Measuring Your PD

What does this mean?
A PD (pupillary distance) is a measurement used to determine the proper lens shape and alignment of your prescription correction to your line of vision.

It is the distance measured (in mm) from center of your left pupil to center of your right pupil

Measuring your PD:

Ask Your Optometrist

  1. Ask your Optometrist to provide you with your PD measurements….. This is always the most reliable resource

 If not provided by your Optometrist, you will need a ruler to take the measurements. 

Measure Yourself
