    To take your PD-ready photo you'll need a few items. Grab your camera and a card with a magnetic stripe. This could include a library card, gift card or credit card!

  • Step Two

    Take a photo of your face with the card under your nose. The card's magnetic stripe should be visible to get the best measurement. Once you take the photo, drag and drop it on the marked position.

  • Step Three

    Press the "Measure PD" Button and it will begin the measurement process. First mark your left and right eyes. This will fix the scale and center your face on the page. Then click the left and right side of the magnetic stripe - this gives us a standard unit of measurement to get your PD. That's it! You'll see your approximate PD at the top right.
