Objective To understand the epidemiological characteristics of low vison and screening positive myopia among primary and middle school students in Zongyang County,and to provide the basis for the prevention and control of students' myopia. Methods A total of 2 116 students from 2 primary schools,2 junior high schools and 1 senior high school in Zongyang County were surveyed. The prevalence of low vison and myopia was analyzed.

Prevalence of low vision and screening positive myopia increased with the increase of school grades,and the severity of low vison was positively correlated with school periods. Prevalence of low vision (81.6%) and screening positive myopia (75.2%) among female students were higher than those in male students (67.6% and 63.7%) in junior high schools. The differences were statistically significant (χ²=12.143,P＜0.05;χ²=8.041,P＜0.05).
