MEASURE YOUR PUPILLARY DISTANCE (PD)

PD is the distance between your pupils, and it's used to help center a prescription correctly in your frames. Before using our PD tool, review the steps below.

1.

Wearing glasses? Please take them off for your picture.

For the best quality photo, please stand in a well-lit area, preferably with a clean background.

2.

Look directly at the camera. You may need to adjust your screen.

For maximum results, your face should be aligned with your camera, looking head-on, with your face centered.

3.

Place any card that has a magnetic strip on your mouth and click capture.

The magnetic strip should be on the top and facing outward. The card should be touching your face.

​

Please note that the card is only being used to accurately measure and scale distance.
