WHAT IS PD?

PD means “pupillary distance,” which is the distance between the center of each pupil. This measurement is used to determine where you look through the lens of your glasses.

If you want to order eyeglasses online, you can either ask your optometrist for your PD or measure it yourself. If obtaining your measurement from your optometrist isn’t possible, no worries—you can measure it from home using ruler!
