HOW TO MEASURE PUPIL DISTANCE (PD)

Pupillary Distance is a measurement of the distance between pupil to pupil. It’s measured in millimeters and can be easily calculated in front of a mirror with a ruler. Just put the 0 directly beneath the center of your right pupil, and then measure the distance to the center of your left pupil. It’s that easy!

If you have any questions regarding your PD or Gunnar Prescription Glasses, please contact us!

NOTE: PUPIL DISTANCE IS THE MEASUREMENT BETWEEN THE CENTER OF BOTH PUPILS. THE UNIT OF MEASUREMENT IS MILLIMETERS.
