Visual acuity problems, access to care, and related academic performance among primary school students in Tanzania: a mixed methods study.

Data included adolescent surveys, medical record extraction, and Primary School Leaving Examination scores.

Overall, based on their worse eye, 6.9% of students had mildly- reduced vision and 4.3% had impaired vision on screening.

Less than 10% of students referred received follow-up care.

Given the prevalence of visual impairment and its potential link to academic performance, governments should consider requiring school-based distance vision screenings.
