How to Measure Your PD?

Pupillary distance (PD) is the distance between the pupils of your eyes. Knowing your PD is important for you to purchase glasses. It makes sure your pupils match the optical center of your lenses. Adult common PD range is between 54-74; kids are between 43-54. Normally, you can find your PD on your prescription. If it is not available on your prescription, don’t worry!
