This study investigated the impact of a school-based vision program on rates of glasses use. The program was implemented in a large urban school district in the mid-Atlantic region. The study utilized a cluster randomized design, assigning schools to either the treatment or a delayed treatment (control) condition. The results showed a significant impact of the program on the number of students wearing glasses in the treatment schools, as well as a significant reduction in use of glasses over time.
