IPD stands for interpupillary distance: the distance between the centers of the pupils. It is one of the measurements used when preparing prescription eyewear. A missing measurement sends shoppers away from the order. They measure IPD in the same browser flow where they choose lenses.
The camera detects facial landmarks, locates the pupils, and calculates a distance. On-screen guidance helps the shopper position their face for the measurement.
Use the result according to your optical provider’s requirements. Camera quality and positioning can affect measurements; confirm prescription fitting details with a qualified optical professional.
No product model is needed for the measurement. Shoppers use a supported browser and camera, and follow the positioning guidance. Test camera permissions in your storefront before publishing.
