pupillary distance regional eye center

Optic Topic by Steven A. Queenan at Regional Eye Optical – Week of June 25, 2019

To ensure that you will derive optimum benefit from your new eyeglasses, it is important to measure the “pupillary distance” (PD), the distance between your two pupils. Because this measurement varies greatly from person to person, it is important that it be accurate and not an estimate or an imprecise reading.

Pupillary distance will change depending on whether an individual is focusing on an object close to the face or something far away.

It is also important to note that human faces are seldom perfectly symmetrical, which means that PD must be expressed as two figure: “monocular distance” (between the bridge of the nose and one eye), and “binocular distance” (the direct distance between two pupils). These measurements can be taken with a small millimeter ruler, called “PD stick,” or a device called a “corneal reflex pupilometer.”
