Pupillary distance or PD is the distance measured in millimeters between the centers of the pupils of the eyes.
There are multiple ways to obtain your PD.
1. Check your current prescription. It is often listed on there.
2. Measure your own PD (or have a friend measure it). Follow the instructions here.
3. If you are an iOS/Apple mobile device user, we strongly recommend using the App EyeMeasure. It is free and can be found by following the link.
Once you have obtained your PD, make sure to include it when you create your account on our website.
