How Peek Vision Went From A Rural Kenyan Clinic To Over 20 Million People Screened

More than a billion people worldwide live with avoidable vision loss — a crisis that one social entrepreneur is tackling with a smartphone and a data-driven model that has already screened over 20 million people. Andrew Bastawrous, founder of Peek Vision, turned a rural Kenyan clinic into the launchpad for a global eye-care revolution, proving that affordable, scalable technology can close the gap between those who see and those who don’t.

Peek Vision began in 2012 when Bastawrous, an ophthalmologist, realized that traditional eye exams were impossible to deliver in remote areas due to expensive equipment and lack of trained personnel. By designing a smartphone-based app that allows community health workers to perform vision tests and even take retinal images, Peek turned a simple mobile device into a diagnostic powerhouse. The data captured flows into a central platform that identifies hotspots of vision loss and tracks treatment outcomes, enabling health systems to allocate resources with surgical precision.

From that one clinic in rural Kenya, Peek Vision has expanded to more than 20 countries, including Uganda, India, and Botswana. The milestone of screening over 20 million people was announced in mid-2026, representing a tenfold increase in just four years. This growth was fueled by partnerships with ministries of health, NGOs like Sightsavers, and technology companies that helped refine the platform. Peek’s models now use machine learning to detect early signs of diabetic retinopathy and glaucoma, conditions that are leading causes of blindness.

The Peek Vision impact extends beyond raw numbers. In Kenya alone, the programme has cut the average cost of an eye exam by 80%, and over 60% of those referred for treatment actually receive it — a rate far above the global average. The system also creates jobs: thousands of local health workers have been trained to use the app, many of them women who now generate income while serving their communities.

Experts say Peek’s model is a blueprint for other public health challenges. “What Peek has done with eyesight can be replicated for hearing, skin conditions, even mental health screening,” noted Dr. Sarah J. Smith, a global health researcher at the University of Oxford. The key, she added, is the combination of cheap hardware, smart software, and a decentralized workforce that puts diagnosis in the hands of the people who need it most.

Looking ahead, Peek Vision aims to screen 50 million people by 2030 and to embed its technology into national health systems. The company is also exploring AI-powered diagnostic tools that never need an internet connection, bringing even the most remote communities into the fold. What started in a single Kenyan clinic is now a proof of concept that the billion-person problem of avoidable vision loss can be solved — one smartphone at a time.
