Pupillary distance (PD) is the measurement (in millimeters) of the distance between the pupils of your eyes. Pupillary distance is an important measurement used to determine the proper lens shape and alignment of your prescription correction to your line of vision.
How do I find out what my Pupillary distance is? Usually the optician will not include this with your prescription, so you should ask your optician for your PD following your eye test. Alternatively we can take this measurement from your existing glasses - your PD doesnât change from one prescription to the next.
