Measure your PD
PD (Pupillary Distance) is the space between your pupils. Everyone’s eyes are spaced apart differently, so we need this measurement to make sure your prescription lenses work for you. Without it, your vision could turn out blurry.
For your benefit, we've got 2 ways to calculate your PD. The first is our handy PD calculator which uses your computer's webcam or smartphones camera and a card with a magnetic strip to calculate your PD. The second is a printable PD ruler you can use to measure your own PD.
Should you struggle with either, please don't hesitate to reach out to our customer service team via chat or at 866-393-2627.
STEP 1: PREPARE
Grab your laptop with webcam or smartphone with a built in camera. Then, find a credit card or card with a magnetic strip- light colored cards work best. Lastly, find a room that is well lit and avoid backlight.
STEP 2: MEASURE
Click the 'Measure PD' button below. Make sure to turn up the volume to hear the instructions clearly.
STEP 3: SHOP AWAY!
Take down your newfangled PD measurements. While you're checking out with your favorite frames, enter those measurements during the enter PD step of checkout.
STEP 1: PREPARE
Use your own metric ruler or print our guide above. To print this page, you must download, then print,
to ensure it prints to scale. In your print settings, use the ‘No scale’ or ‘Actual size’ setting.
When printed at the correct scale, the card should be the size of a credit card.
STEP 2: FOLD
Cut out the PD ruler below and fold it along the dotted line.
STEP 3: GET READY
Stand in front of a mirror or ask a friend to help.
Place the ruler horizontally against your brow, keeping your face straight.
STEP 4: MEASURE
Align the zero directly above the center of your right pupil. Without moving the ruler,
follow it over to your left eye and read the measurement directly over the center of your left pupil.
STEP 5: CELEBRATE!
You did it – you measured your own PD. Now, let’s do some shopping!
