HOW TO MEASURE PUPILLARY DISTANCE
What is pupillary distance?
Your PD is the distance in millimetres between the centre of one pupil and the centre of the other pupil. This measurement ensures that we make your lenses with the prescription exactly where your eyes require them, resulting in superior vision!
Types of pupillary measurements
Single PD and dual PD measurements are the two types of PD measurements.
Single PD
The distance between the centres of one pupil and the centres of the other is referred to as the single or binocular PD measurement. A single PD measurement yields a single value, such as 60, 63, or 55 mm.
Dual PD
The distance between the centre of each pupil and the bridge of the nose is referred to as dual or monocular PD. Dual PD measurements consist of two numbers. For instance, if the dual PD is 31/33, the first number refers to the right eye and the second to the left eye.
