How to measure PD
Pupillary Distance is the distance from the center of the pupil (black circle) in one eye to the center of the pupil in the other.
Pupillary Distance measuring instructions:
- Put the millimeter ruler on the bridge of your nose.
- Ask someone to stand approximately 2 feet away from you and measure the distance between the centers of your pupils (the black circle in your eyes).
- You can measure pupillary distance yourself by using a mirror.
You may ask your doctor or a licensed Optician to obtain this information from your file or they can take the measurement for you.
Note: Typical adult’s pupillary distance measurements are as follows: (54mm to 66mm). Typical children’s pupillary distance measurements are as follows: (41mm to 55mm). * New York State residents must have their pupillary distance measured by a doctor or licensed Optician.
