The Pupillary Distance (PD) is the distance between the center of your two pupils. It is a necessary measurement for our lab to ensure that your prescription is properly centered within the lenses.

1. How to obtain your PD: 

Ask your optometrist during your next eye exam. 

If it is not on your prescription, we can measure it in any BonLook store (for free) with an optician or from a photo!

2. How to take the photo to measure your PD:

- Remove your glasses and stand in a well-lit area so that your pupils are visible.

- Hold a standard-sized card (like a credit card) under your nose, against your face.

- Make sure your head is straight and you're looking directly at the camera (not at your screen).

- Take the photo from about 30 cm away from the camera (about the length of a ruler).

- Send us your photo: 

Upload it to your BonLook account, in your order, or email it to support@bonlook.com. 

Minors: The measurements must be taken by an optician in-store.
