Measuring your PD

WHAT IS PD?

A personalized fit starts with measuring your pupillary distance-that's the space between the centers of each of your pupils. It's measured in millimeters and tells the lens maker where to put the optical center on each lens. You can ask your eye doctor to include your PD measurement on your prescription, or if you don't have it, here's how you can measure it yourself.
