Your eyes are set at a particular distance from each other, which can vary from person to person. The distance between the center of one pupil to the center of the other is referred to as Pupillary Distance. 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.
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.
Usually, the PD is measured during your eye test.. If your PD is not included in your glasses prescription, call your doctor to get the PD as it is saved with him/her. The second option is to measure it easily byyourself!
Remember to always ask for your PD and a copy of your glasses’ prescription at each of your eye examinations! If not, you can always measure it yourself pretty easily!
