Research

In order to support myopia prevention efforts, this study aimed to investigate the prevalence of refractive errors among 6-15-year-old school children in Suining City, Sichuan Province. Among 1138 participating students, myopia was prevalent in 59.1%, hyperopia in 5.0%, astigmatism in 38.4%, and emmetropia in 25%. Prevalence of myopia increased with age and learning stage, with most students having moderate myopia. Myopia was more common in girls than boys, and the mean spherical equivalent increased with age. High myopia was more prevalent in boys than girls. The study suggests a significant myopia issue in Suining City and provides valuable data for myopia control programs. The prevalence differences may be due to increased near-work, electronic device usage, and genetics. Strategies like reducing learning burdens, limiting electronic device use, and promoting eye care exercises are recommended to address myopia in school-aged children.
