About this app

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)

PROGRESSIVE LENS MEASUREMENTS
• Vertex distance
• Pantoscopic tilt
• Frame wrap / inclination angle

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.
AI-powered optometry measurements from a photo. PD, fitting height & more.

Designed to fail to force you to purchase. wont let you edit your adjustments if you accidentally press next. 2 free attempts max which have to be done perfectly and also didn't clearly state to have glasses on.

This works great now. No more credit card sizing. It now sizes based on the glasses you are already wearing and the size printed on the glasses. The instructions and tutorials were easy to follow. I do understand the bad reviews, as i have attempted to use apps that work that way, but this app no longer does, as of the time I'm writing this.

The app has a friendly and easy-to-use interface. It guides the user through the necessary steps for eye measurements related to glasses. I'm curious if this could be used as well to measure pupillary distance for VR headsets. Note, I couldn't get the camera function to work even though I gave the app the necessary permission.
