The PD, or Pupillary Distance, as the name suggests, is the distance between the centre of your pupils. It is an important measurement when purchasing glasses, but as the guide below shows, it is simple to measure.
This is the easiest method for measuring your PD. Please follow the guide below:
- Asking a Friend to help you using a ruler. With your friend sitting opposite you at the same height, ask them to place a ruler across your forehead just above your eyes with the millimetre side facing upwards.
- Ask your friend to close their right eye and you then look directly into their left eye. Ask your friend to slide the ruler so that the zero value is in the centre of your right pupil and to keep the ruler very steady across your forehead.
- Ask your friend to close their left eye and for you to look directly into their right eye. Your friend will then read off the measurement to the centre of your left pupil.
That is all there is to it. Please see the diagram above to help you further.
P.S. You will require a prescription which is less than 2 years old.
We sell only single vision prescription (near) or single vision prescription (distance).
Alternatively, if you have an older prescription, it may contain your PD.
