Pupillary Distance Help

How to measure your PD

  1. Find a ruler that can measure in millimetres
  2. Stand in front of a mirror, close enough to read the measurements, and look into the distance.
  3. Rest the ruler on your nose and line up the 0 on the ruler to the outer edge of your left pupil. The outer edge is closest to your ear.
  4. Holding the ruler steady, find the number that aligns with the inner edge of your right pupil. Your PD should be between 55 and 70 for most adults.
  5. Check the measurement a few time to ensure it is accurate.
