FAQ
Frequently Asked Questions
IPD (interpupillary distance) is the distance between the centers of your pupils. It is essential for fitting prescription lenses correctly — an inaccurate IPD can cause eye strain, headaches, and blurred vision, especially with progressive and multifocal lenses.
Our tool achieves sub-millimeter accuracy (within 0.5 mm) compared to clinical pupillometers. It uses 468-point face mesh tracking and proprietary calibration algorithms to deliver reliable results from a standard webcam.
No. Our algorithm uses the natural geometry of the face as a reference, eliminating the need for any physical calibration tools. Just look at the camera and follow the on-screen instructions.
The IPD tool is ideal for online optical retailers, telehealth eye care providers, and any eyewear brand that wants to help customers get accurate measurements at home before ordering prescription glasses or lenses.
