How To Measure Your Pupillary Distance (PD)


Hey there! Let me help you with your Great Eye Glasses order today.

It’s fun and easy shopping for new glasses in the comfort of your own home. But, you are going to need to find your pupillary distance, or PD, before you place your order.

Let’s start by explaining what pupillary distance, or PD, is.

PD is the distance in millimeters measured from the center of one pupil to the center of the other.

Let me explain to you why this is important.

This is important because each and every lens has an optical center that’s placed directly over the pupil for the very best vision. This is super easy to do, whether you’re doing it yourself or having somebody help you. All you will need is a mirror and a ruler.

Let’s start by standing about eight inches from your mirror. Now take the ruler and place it against your brow. First, close your left eye and align the ruler to the center of your right eye pupil. Still looking forward, close your right eye and align the ruler to the center of your left eye pupil. Measure this three to four times to make sure that it’s accurate. You have now found your PD.

Want a friend to help? Here are some tips for when a friend is helping. If a friend is measuring your PD, keep both eyes open and have your friend place the 0 on the millimeter ruler over the center of one pupil. Then measure the distance from one pupil to the center of the other pupil. Have them crouch or sit while you are standing so they are out of your field of vision.

Keep your eyes as still as possible. Look over his or her head at something approximately ten to twenty feet in the distance. Do not look at the person measuring.

Congratulations on finding your PD. Now that you have your PD and prescription you can move on to the fun stuff, like shopping! Thank you for watching this video on how to find your PD. Be sure to check out some of our other videos, as well. See you!
