Pupillary Distance or PD, is the distance between the center of each eye. It is an important measurement for glasses, as it allows us to ensure that the center of the optical lens in your glasses sits in front of the center of your eyes. Misalignment can cause headaches and strain.
We offer a free Expert Pupillary Distance Measuring Service to all our customers.
