Myopia among schoolchildren in East Asia and Singapore

Myopia is highly prevalent among schoolchildren in East Asia and Singapore; however, its prevalence has been gradually increasing, and the number of population-based and non–population-based studies assessing this trend has increased in the past 10 years. Although the causes of this high prevalence in East Asia and Singapore remain poorly identified, related studies have discussed the associated risk factors. We summarize the data concerning the prevalence rates reported in related studies and discuss the most crucial risk factors among these schoolchildren.
