Measure your pupillary distance

Pupillary distance (PD) is the distance between the centers of your pupils, measured in millimeters. It's a crucial measurement for accurately centering your lenses and ensuring optimal correction.

It can be given as a total value (e.g., 63 mm) or as monocular values, measured from the center of the nose to each eye (e.g., 31.5 mm / 31.5 mm). The latter allows for more precise alignment, especially for progressive lenses. In adults, PD typically ranges from 58 to 68 mm, with an average around 63 mm.

This measurement is especially important for prescription glasses, as it directly affects the quality of vision correction.

Some prescriptions don’t include pupillary distance. That’s exactly why we’ve created this quick and easy tool to help you measure it online.

If you alreadyhave completed your order without this measurement, don’t worry — we’ll help ensure your lenses are perfectly centered.

Our tool allows you to measure your pupillary distance using a simple photo. Just position yourself in front of your computer or smartphone camera while holding a standard-sized card (such as a bank or loyalty card, etc.) in front of your face, as shown by the watermark. This card is used as a reference to precisely calculate the distance between your pupils. No download is required — everything happens directly in your browser.

If you run into technical difficulties (inactive camera, blurry image, etc.), no worries: our customer service can assist you in taking the measurement manually at a distance. And don’t worry about your photo either: if it can’t be used, we’ll simply get in touch to take a new one together.
