Measuring...
This measurement uses your face proportions for calibration. Keep your face at arm's length (~40cm) from the camera and look straight ahead.
Disclaimer: This webcam-based PD measurement is an estimate only (±2mm accuracy).
For the most accurate results, please have your PD measured by an optician.
Using an inaccurate PD may affect the quality of your prescription lenses.
