Jason Sauer UX - Online Vision Test Prototype

The Challenge

Patients often let their prescriptions expire due to the inconvenience or cost of scheduling eye exams. Our business needed a way to retain these customers by offering an accessible, compliant method for prescription renewal.

The biggest technical hurdle was building a voice-activated process that could reliably guide users through a Snellen test via the web, well before voice interfaces were mainstream.

The Strategy

We created a browser-based prototype that used speech recognition to progress users through the test. The user would stand at a distance from a mirror while holding their phone, which displayed a reversed Snellen chart.

I led the experience design and user testing, validating interaction patterns with real users and identifying friction points in both UI and physical setup. Our cross-functional team iterated quickly to ensure technical feasibility and clinical accuracy.

The Outcome

The prototype enabled users to complete vision tests and renew prescriptions remotely—removing friction for patients and extending the lifecycle of existing customers. By minimizing lapses in prescription validity in compliance with health and regulatory standards, we unlocked new opportunities to drive contact lens and glasses sales. The project also positioned us as early innovators in digital eye care and paved the way for future telehealth initiatives.
