What is my Pupilary distance (PD), and how do I obtain it?
Your pupilary distance (PD) is the distance between the centres (pupils) of each of your eyes, measured in millimetres. Your PD measurement is used when we take a lens with your prescription and customise it to both fit your frame and you. To be effective, a lens must be cut so the centre is directly in front of your pupil. Without your PD we have no idea where that point is for you and as the diagram below shows, everybody is different. Your PD can be provided in minutes by your optician or doctor, and so we highly recommend that you ask for it when you have your eyes tested. Alternatively, you may also choose to use an average PD, which is provided for you as a default when ordering.
