A global child eye-health initiative using technology, partnerships and school-based screening to help every child see clearly.
OSaaT Vision (OSaaT) is a global partnership for school eye health that strives to deliver accessible, comprehensive and affordable high-quality eye care and vision services — including vision screening, eye examinations, spectacles, low-vision services and referral services — to children in need. OSaaT raises awareness and influences policy and practice at global, national, regional and local levels with key organisations and stakeholders.
OSaaT combines healthcare delivery, education and awareness, research and technology, bringing affordable, high-quality eye care to children wherever they learn. It incorporates a mobile screening platform and works with teachers, trained technicians, optometrists and ophthalmologists to achieve its aims.
80% of classroom learning is visual, yet hundreds of millions of children cannot see the board. Early detection rewrites the curve.

If we want every child with uncorrected refractive error to see clearly, we have to overcome the lack of awareness, access and adoption — all at the same time.
Little awareness of the importance of eye health in families, schools and communities.
Over 90% of children with uncorrected refractive error live in developing economies where affordable eye-care is limited.
Social stigma prevents many children from wearing the glasses they need to learn.
OSaaT was created to accelerate and enhance access to eye care services for children globally through scalable, affordable, school-based solutions.
Vision screening, eye examinations, spectacles, low-vision services and referrals that are accessible, comprehensive and affordable.
Raising awareness and influencing policy at global, national and local levels with key organisations and stakeholders.
Educating children, parents and teachers about the importance of good vision and the rising risk of myopia.
Developing partnerships with local optometry and other organisations to deliver on our objective and agenda.
An Android-first workflow built for technicians and non-specialists in remote and underserved areas.
Government and NGO partners help identify and onboard participating schools.
Each eye is tested separately as the child indicates the direction of the E across multiple calibrated rounds.
An accurate visual acuity score is generated instantly on-device, with no bulky equipment required.
Children below the screening threshold are referred for eye examination and refraction.
Best corrected visual acuity is determined. Children identified with ocular problems are referred to an ophthalmologist.
Spectacles are prescribed and delivered back to the child at school.
Screening, referral and prescription data syncs securely for research and program reporting.
Donors, governments and program teams receive transparent, evidence-based impact reports.
Built for ophthalmic technicians on the ground: fast, offline-capable and synced to a secure cloud the moment connectivity returns.
Real programs, real numbers, real children, across three continents and growing. Swipe through each country to see how OSaaT is taking shape on the ground.

A global coalition of founding institutions, funders and program implementers, united around one mission.
The outcome of the first Global Symposium on Child Eye Health (Feb 2025), declaring vision a fundamental right essential to health, education, inclusion and human development.
The Statement aligns with WHO's SPECS 2030 goals to reduce uncorrected refractive error in children globally and provides a foundation for policymakers, stakeholders and communities to advance the child eye-health agenda.
For NGOs, governments, corporates, donors and schools: choose how you want to make a difference.
