What is Pupillary Distance (PD#)?

Pupillary Distance (PD#) is the measurement of the distance between the centers of your pupils. It is a crucial factor in crafting prescription lenses, ensuring they are accurately aligned with your eyes. Having an accurate PD measurement enhances visual comfort and optimizes the performance of your eyewear, contributing to a seamless and personalized vision experience.

Pupillary Distance (PD) can be expressed as one number (binocular PD), representing the distance between both pupils. Alternatively, it can be specified as two numbers (monocular PD), offering separate measurements for each eye. The use of monocular PD is especially beneficial for individuals with facial asymmetry, ensuring precise customization of prescription lenses for optimal visual alignment.
