PD stands for pupillary distance, which is the distance between the centers of each eye. This measurement is highly recommend to make sure that your glasses come out right.
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!
Your PD will ensure that your glasses are customized to fit you perfectly. Please email us the photo or PD to avoid delays!
