中国近视眼防治的挑战及应对

Challenge and strategy for prevention of myopia in China

要目前我国青少年近视眼患病率很高,中小学生已达27.65%～53.80%。长期视近及缺少户外活动是其主要原因。流行病学调查显示,户外活动对近视眼有防治作用。我们建议中国的中小学生应保证每天3.5小时户外活动时间,即上学路途0.5小时,课间户外活动1小时,户外上课1小时,放学后户外活动1小时,以期降低中国学生近视眼的患病率。

The current prevalence of myopia has been as high as 27.65%-53.80% among adolescents in Chinese schools. The major reasons are too much near-work activity and lack of outdoor activity for a long time. In order to reduce the prevalence of myopia in Chinese adolescents, we suggest that Chinese students should have 3.5 hours outdoor activity everyday, including 30 minutes travel between home and school, 1 hour outdoor activity between classes, 1 hour outdoor sport class at school, and 1 hour outdoor activity after school.
