Your Pupillary Distance (PD) is the distance between the pupils in millimeters. This measurement isused when prescription lenses are being mounted in your frames. The most common measurements are between 58mm and 68mm. The simplest method is to ask your Eye Doctor or Optometrist for your PD measurement. If you do not have a PD measurement it is common practice to use 63mm as the average.
