    PD stands for Pupillary Distance, which is the distance between your pupils in millimeters. Your PD is very important for accurately fitting your lenses to achieve vision acuity. Generally speaking, the average PD for adults is 55-70 mm and for kids is about 50-70 mm. A difference about 2-3 mm is allowable.
