近视是一种全球性的屈光不正,近年来近视发生的年龄日趋提前,发生率逐年提高.中国是近视高发地区之一,随之而来的视力矫正的需求日渐扩大,而高度近视引起的并发症及致盲风险不得不引起重视.一些调查发现,近视已经成为我国低视力的第一大因素,致盲的第二大因素.近视的生化机制目前尚不清楚,近年来多个流行病学研究均发现增加户外活动时间可减少近视的发生,针对其抑制近视的机制进行研究和分析,将可进一步利用户外活动而获得有效缓解近视的方法和手段.

Myopia is the most prevalent refractive error.In recent years,the age of myopia onset is becoming earlier and earlier,and the prevalence is increasing year by year.China is among regions of most myopic occurrence across the world,reulting into higher need of visional correction.The worse is complications and risks to blindness brought by myopia.According to a few investigations,myopia is the first factor against lower vision and second factor against blindness.However,the mechanism underlying myopia pathology is still yet to know.Recent epidemiologic studies revealed that increased outdoor activities reduced myopia occurrence.Insights into the mechanism underlying outdoor activites inhibiting myopia will facilitate way to prevent and/or cure myopia.
