Measure your PD in three simple steps.

  • 1.

    Take a Photo

    Position your face within the dotted circle.

    Using a card with a magnetic strip on the back (such as a library card, student ID, or gift card), hold the card against your upper lip and directly under your nose. Make sure the magnetic strip is facing the camera.

    Look straight at the camera with your eyes wide open and click “Capture”.

    If you can’t see your pupils clearly or the picture is not level, click “Back” to take another picture.

  • 2.

    Take Measurement

    Click on the card’s magnetic strip and move the arrows to adjust the green box so that it perfectly outlines the magnetic strip.

    Place the white crosshairs directly over each of your pupils, and align the center hash mark with the center of your nose.

    Use the zoom button in the upper toolbar to get the most accurate measurement. As a rule of thumb, the normal range for adult PD measurements is 50mm to 75mm.
