What is PD?
Your eyes are set at a particular distance from each other, which can vary from person to person. The distance between the centre of one pupil to the centre of the other is referred to as Pupillary Distance (PD).
Typically, the Pupillary Distance falls in a range between 54 and 65 mm. As children grow up, their PD keeps on changing but once they become adults, this value remains constant.

Your prescription can either have one PD value or two PD values, knowing your PD is very important so that you may buy prescription glasses that fit your face perfectly. It is essential that your glasses’ lenses are directly focused over your pupils so that you can enjoy proper vision.
