What is Pupillary distance (pd)

Pupillary Distance (PD) is the measurement of the distance between the centers of the pupils in each eye. This measurement is essential for ensuring the correct alignment of lenses in eyeglasses, allowing for accurate and comfortable vision. Knowing your PD is crucial when purchasing prescription glasses, as it helps in positioning the optical center of the lenses directly in front of your pupils, ensuring optimal visual clarity and comfort.
