P.D (Pupillary Distance)

Pupillary distance is an essential measurement. It is the distance from the centre of one pupil to the centre of the other pupil measured in mm.

Each spectacle lens will have an ‘optical centre’, this point should be placed directly in front of the centre of each of your pupils. That way, your eyes are looking through the best point on each lens.

The P.D is not routinely written on a prescription, you can ask for this from your Opticians, or ask them to add it to your prescription when you are tested.

If you experience difficulty in obtaining this measurement we can take it  from an existing pair of your glasses.

We will not use average figures for this, because of its importance, so we cannot proceed with a reglaze without it.

We have a free App, with a 'P.D Capture' button, it will take a picture and email it direct to us. You can of course email us a head-shot digital photo of you wearing the frame you want us to reglaze. We can scale this and obtain the p.d very accurately.

If you have ordered prescription lenses with us before we will already have all the measurements we need on file!
