Pupillary distance (PD) measures the distance between the centers of your pupils in millimeters. This measurement is used to determine where you look through the lens of your glasses and should be as accurate as possible to provide optimal vision. Your eye doctor will usually measure your PD during an eye exam and will include it with your prescription. If you did not receive your PD measurement we ask that you please contact your eye doctor and request it prior to placing a custom prescription order.
If you are unable to obtain your PD measurement from your provider Contact us to speak to one of our Rx specialists so they can assist you further.
