Pupillary distance (PD) measures the space between the pupils of your eyes. Knowing this measurement is important to make sure your eyes match up with the optical center of your lenses. The average adult’s PD is between 54-74; kids' are between 43-54.
How to Measure Your PD?
Stand 8 in. away from a mirror.
Hold a ruler against your brow.
Close your right eye then align the ruler’s 0 mm with the center of your left pupil.
Look straight then close your left eye and open your right eye.
The mm line that lines up to the center of your right pupil is your PD.
Check out the graphic below for more information and to learn how your friend can help you measure your PD.
Armed with your PD and prescription, you can shop at Fabbrica Occhiali Italiani to find your perfect pair of glasses.
How to Measure Your Pupillary Distance
What Is Pupillary Distance?
Pupillary Distance (PD) is the measurement from the center of one pupil to the center of the other. If you are getting single vision reading glasses, use your near-vision PD, which is your distance vision PD lowered by 3 mm.
PD = 62 mm
Why Is It Important?
Every set of prescription lenses has an “optical center,” which is determined by pupillary distance. Pupillary distance is used to determine where you look through the lens of your glasses and should be as accurate as possible.
Measure The Distance
Your prescription may tell you your PD. But if the PD is not available, use your friend or a mirror to help you figure it out.
