WHAT IS PUPILLARY DISTANCE?
Pupillary distance (PD), or interpupillary distance (IPD), is the distance between the centers of the pupils when both eyes are looking straight. It is measured in millimeters. The average PD for adults is between 54mm to 74mm, and for children, between 43mm to 58mm.
WHY MEASURE PD?Pupillary distance (PD) has a huge influence on our comfort level when we wear glasses. You must provide your PD when filling out the prescription form on our website.
< THE SUITABLE PAIR OF GLASSES >The PD of the eye deviates from the distance between the centers of the lenses. If PD is small, wearing large-frame glasses will cause focus deviation between the pupils and the centers of the lenses.
< OVERSIZED FRAME >
HOW IS PUPILLARY DISTANCE MEASURED?Your eyeglass prescription will usually come with pupillary distance (PD). What if you don’t know your PD?
