Current Prevalence of Myopia and Association of Myopia With Environmental Factors Among Schoolchildren in Japan

Abstract

Although the use of noncycloplegic autorefraction with a cutoff of -0.50 D could lead to overestimation of results, these findings suggest that the current prevalence rates of myopia among elementary and junior high school students in Asia are high, especially if the results from these 2 schools are generalizable to all schoolchildren in Japan and Asia.
