|---|---|
| Assess whether the impact of glasses provision on student learning varies by other student or school characteristics (including baseline VA, sex, school quality). Improvement in learning scores from baseline to endline will be larger among children with higher baseline visual impairment severity. Improvement in learning scores from baseline to endline will be larger among children in higher quality schools. Improvement in learning scores from baseline to endline will be larger among children in schools that teach using a blackboard. Timepoint: 3, 6, 9, 12 months | — |
