How to measure your PD

• Use a normal MM ruler and stand arms length from the mirror, put the 0 of the ruler level with the edge of your pupil nearest to your nose.
• Then, keeping the ruler in place, look straight ahead and read the measurement from the edge of your pupil in your other eye, but this time use the outside edge of the pupil (see diagram).
• This will allow for a more accurate reading as it is sometimes difficult to pinpoint the centre of the pupil.
