Initial prevalence of myopia was high in the HD school. However, it became similar between the two schools after 6 months. The mean AL of 155 emmetropic children was 22.7 ± 0.63 mm. In the 185 children with AL ≥22.7 mm, there was no difference in the AL change between the two schools. However, the change in AL in 107 children with AL <22.7 mm was significantly
larger in the LD school (0.19 mm) than that in the HD school (0.15 mm,
p = 0.049). Parental myopia, near-work and outdoor activities were not different between the two schools
