Pupillary Distance is the measurement in millimetres of the distance between the eyes and is used to ensure that your lenses are positioned properly to give you clear vision. PD value is required when ordering a new pair of glasses.
In order to make your eyeglasses custom to your face, we need to know the distance between your pupils so the centre of the eyeglass lens, which holds the clearest vision, sits directly in front of your pupil.
Note: If you are unable to measure yourself, have someone help you!
You can measure your own PD by following the steps below.
The measurement you just got is your Distance PD. If you need your PD for prescription reading glasses then you will need to know your Near PD which is calculated as 2mm less than your Distance PD.
For example: Distance PD: 62mm / Near PD: 62 - 2 = 60mm
