Pupillary Distance

Pupillary Distance (PD)

 

Measuring your PD

 

This measurement is the distance between the centre of your pupils that is measured in millimetres.

Opticians do not tend to give out this measurement as it encourages patients to buy their spectacles from them. It is usually written as one measurement such as 60 (60mm) but can also be shown as R 29 L 31. When written like this it is the individual distance from you right and left pupils to the centre of your nose. The individual measurements for the centration of right and left pupils is important for the dispensing of varifocals due to the more complex nature of the lens properties where there can be distortion.

When Varifocals, High Prescriptions or Prisms are ordered the measurement is usually split individually. For most Single Vision prescriptions it is written as one value.

If you do not know this measurement and don’t want to measure it yourself then we will make your PD the national average (63) for men and (60) for women. Further details can be found in our Terms & Conditions.
