Helping every child see, one school at a time.
Technology, partnerships and data working together to screen, refer and correct children's vision, school by school.
A pocket-sized vision clinic for every classroom.
One School at a Time (OSaaT) is an Android application designed to screen the vision of schoolchildren efficiently. Ophthalmic technicians assess visual acuity using a digital tumbling-E test — children identify the direction of the E while each eye is tested individually.
Results are captured instantly, helping identify children who need referral for professional eye examinations and prescription spectacles. Records, referrals and outcomes sync to a secure cloud for large-scale, evidence-based programs.
