How it works

A simple workflow built for scale

From the first child screened to the last impact report, OSaaT works the same way in every school, anywhere in the world.

Step 1

Government and NGO partners help identify and onboard participating schools.

Step 2

Each eye is tested separately as the child indicates the direction of the E across multiple calibrated rounds.

Step 3

An accurate visual acuity score is generated instantly on-device, with no bulky equipment required.

Step 4

Children below the screening threshold are referred for eye examination and refraction.

Step 5

Best corrected visual acuity is determined. Children identified with ocular problems are referred to an ophthalmologist.

Step 6

Spectacles are prescribed and delivered back to the child at school.

Step 7

Screening, referral and prescription data syncs securely for research and program reporting.

Step 8

Donors, governments and program teams receive transparent, evidence-based impact reports.
