What is your PD (Pupilary Distance) and how do you find it

Your PD (pupillary distance) number is the distance between your eyes, measured between the centre points on your pupils. We need your PD measurement to ensure your glasses fit you perfectly.

Your PD can sometime be found on your prescription provided by your optometrist. If you do not have this you can contact your Opticians who will provide it for you, or you can measure it yourself.


How to measure your pupillary distance (PD)


So, first thing's first: what is is pupillary distance (PD)? Essentially, its the distance between the centres of your pupils (the black bits in the middle of the eyes).
Your PD is an important part of your glasses prescription that makes sure you're looking through the best spot in your lenses for lear vision. We'll need this measurement if your buying your specs online.
Generally the PD is given by your optician. However if you do not have it there are a few options; you can request it from your optician, use our online tool to allow it to measure it for you or follow or clear and simple step by step guide.
