What is my PD and why do I need it?

PD stands for pupillary distance, which is the distance between the centers of each eye. This measurement is critical as it allows us to place the optical center of the lens perfectly in front of your eyes.

If your prescription does not include your Pupillary Distance (the distance between the centers of each eye), you can either ask your optometrist if they have it on file for you, or you can take a picture at home and email it to us and we’ll measure it for you!

Please email us the photo or PD to avoid delays!
