Description
The professional optometry measurement app with AI-assisted pin placement — 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. AI face detection places measurement pins automatically, so you get accurate results in seconds instead of minutes.
HOW IT WORKS 1. Take a photo of the patient in the frame 2. Calibrate using the known lens width — or let AI estimate lens edges 3. AI detects face landmarks and places pins automatically — drag to fine-tune 4. Get all your measurements instantly
AI-ASSISTED MEASUREMENTS OptoExpert uses on-device face detection to automatically locate pupils, bridge, and lens edges. AI places your measurement pins with one tap — then drag to fine-tune for perfect accuracy. AI also estimates lens edges during calibration, saving time on every exam. All processing happens on your device — no data leaves your phone.
SINGLE-VISION MEASUREMENTS • Pupillary distance (PD) — monocular left & right • Bridge width (DBL) • Lens width / eye size (A measurement) • Lens height (B measurement) • Minimum blank size — auto-calculated from shared points • Pupil to bottom of lens (left & right) • Pupil to bridge center (left & right) • Effective diameter (ED)
BUILT FOR OPTICAL PROFESSIONALS • Guided workflow with floating pin labels and coach marks • Auto-calculated measurements reduce manual steps • Save and revisit patient exams • Export results as PDF to share with labs • No ads — a professional tool, not a consumer gimmick • Works offline
WHY OPTICIANS AND OPTOMETRISTS CHOOSE OPTOEXPERT Traditional pupilometers, pd meters, and rulers are slow and inconsistent. iPad-based measurement systems from Essilor and Zeiss cost $50–100/month plus hardware. OptoExpert gives you AI-powered digital eye measurements from any Android phone for a fraction of the cost.
PRICING Free to try with your first 2 eye exams. $4.99/month for unlimited optometry measurements.
Used by independent opticians, optometrists, and ophthalmology professionals worldwide as a digital AI pupilometer for eye exam measurements, pd measurement, lens fitting, and progressive lens ordering.
Recent changes: Free trial UI on buy screen. 7-day free trial badge and messaging.

★☆☆☆☆Molly Daniels· Feb 18, 2026
They don't tell you lenses are required and if you're just trying to get your pupillary distance measurements, so you can order glasses online, it's not possible.
★☆☆☆☆carley walls· Nov 4, 2025
I only want to know pupillary distance. To do that you need to do 2 exams, to take 2 exams you need to subscribe and pay.
★☆☆☆☆Aaron Gresham· Jul 22, 2025
The measurement tool doesn't measure anything.
