Optic Topic by Steven A. Queenan at Regional Eye Optical – Week of April 2, 2017
In order for a new set of prescription lenses to correct the wearer’s vision properly, the center of each lens must be precisely centered over the corresponding pupil of each eye. With this in mid, the “papillary distance” (PD) measurement will be taken, which determines the distance (in millimeters) between the pupils.
One way in which this measurement can be taken, called “binocular,” is a pupil-to-pupil measurement. Another way to measure, called “monocular,” is a per-eye measurement from the pupil to the middle of the face. These are most often used when the face is not perfectly symmetrical, meaning one eye is closer or farther from the middle of the face than the other. When fitting eyeglasses, it is also important to measure the temple length (also known as the arm length) and the bridge size.
