A simpler way to get your PD
Ordering glasses online usually stalls at one small box on the checkout form: pupillary distance. Most prescriptions don't include it, and getting it often means another trip to the optician. This tool exists so you don't have to make that trip.
Pupillary Distance Calculator measures your PD in your browser — with your camera or a photo — and returns total, dual, and near PD in under a minute. The camera feed never leaves your device. No account, no upload, no signup.
We build for accuracy and privacy first. Every result includes a confidence range so you know how much to trust it, and the tool is honest about what it is: a confident estimate, not a medical measurement.
What it does
Total, dual & near PD
One tool for single-vision and reading glasses.
How it works
Camera, photo or ruler
Use what you have — no extra hardware.
Why trust this tool
- — Built with careful face-mesh and ruler-scale math, not a guess.
- — Shows a confidence interval so you can judge before you order.
- — Works offline after load — your image stays on your device.
- — Honest limits: we recommend confirming high-prescription PD with an optician.
