OptoExpert: AI Lens Measure
Pro Optometry Measuring
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The professional optometry measurement app built for opticians, optometrists, and ophthalmology professionals.
Measure everything you need for a glasses order — PD, fitting height, progressive values, and more — directly from a photo of the patient wearing the frame.
HOW IT WORKS
1. Take a photo of the patient in the frame
2. Calibrate using the known lens width or bridge size
3. AI detects face landmarks and suggests pin positions
