What is my PD?

(also called Pupillary Distance, Inter-Pupillary Distance or Pupil Distance)

PD is the distance between the centre of one pupil to the centre of the other pupil. Prescription glasses are made so that the distance between the optical centres of the glasses' lenses, is the same as your PD. PD varies from person to person but once you are an adult, your PD does not change. Therefore, as an adult, if you have had it measured, then it will still be the same, even if your spectacle prescription has changed. Once you know your PD, you do not need to measure it every time you buy prescription glasses.

PD is measured either during the eye test or when prescription glasses are ordered. Obviously we cannot measure your PD over the internet, so it is best to make sure your PD is included in your glasses prescription.

The Diagram below represents a PD of 62mm.
