How to Measure Your Pupillary Distance

Pupillary distances (PD) correspond to the distance between the center of your nose and your pupils. Having exact pupillary distances is important in the creation of your prescription glasses.

Idealy we need two separate measurements (PD right eye and PD left eye). Only an optician can measure them.

Unlike prescriptions, pupillary distances do not change after the age of 16 on average. Once known, you can reuse them for all your glasses orders. We will provide them to you and keep them securely in your Visionet file.

How to do it? There are several solutions:

1 - If you have had glasses made by an optician before, you can call him and ask for the measurement of the right and left half-pupillary distances they used for your old glasses.
2 - When you take your eye test, ask the optician or the doctor to write your PD on the test result.
3 - Take a photo of your face with a scale (credit card or other card of exactly the same size/shape.).

Ask someone to take a front-facing photo of you, positioning the camera at eye level and 40cm away from your face.

Hold the credit card under your nose or a ruler on your forehead

Remove your glasses and keep your eyes wide open, looking at the camera
(you may hide the credit cart number as we do not need them)

Here is a good example
Pay attention to the following points

Stand straight and look straight ahead

Face directly forward, without showing one side of the nose more than the other or one ear more than the other

The card is placed straight and attached to the mouth under the nose
