How to use our PD measurement tool.

Grab a regular card with a magnetic stripe on the back. Student IDs, credit cards and gift cards work well as measurement tools.

Place the card under your nose and try to keep its distance from the camera the same as your eyes. Snap the picture and drop it on the marked area.

Click "Measure PD" and begin by marking your left and right eyes. The image will resize and center after which you can mark the left and right side of the magnetic stripe. Your PD will be shown at the top right!
