PD (Pupillary Distance) is a measure of the pupil distance, from the right eye to the left eye under natural straight viewing conditions, unit: mm.
The pupil distance is the sum of two distances from the bridge of the nose to the pupil of each eye, so there will be patients with different eye spacing.

The way to measure the pupil distance is quite simple, you can do it yourself or ask another one to help you. All necessary tools are a ruler in millimeters (mm) and a mirror.

Step 1: Stand about 20 cm away from the mirror, not too far away and close enough that we can see the pupils of the eye. Place the ruler on top of the brow area to make it easier to measure.

Step 2: Close the Right eye and place the "0" position of the ruler corresponding to the pupil of the Left eye on the eyebrow (or on the forehead).

​Step 3: Without moving the ruler, close the Left eye, open the Right eye and measure the distance from the "0" to the pupil in the right eye. This distance (in mm) is the single pupil distance.
