澳大利亚研究人员发现,晒太阳是儿童预防近视的一个关键因素。澳大利亚视觉科学研究中心的伊恩·摩根博士表示,在过去的30年间,东亚的近视率急剧上升。研究人员将居住在新加坡和悉尼的具有中国血统的孩子进行对比,对比结果显示:居住在新加坡的孩子的近视率比居住在悉尼的孩子高10倍。但是,居住在悉尼的孩子花费在近距离用眼的活动上的时间更长,他们每周的读书量是居住在新加坡的孩子的两倍。然而,他们的主要差别是,悉尼的孩子周末在室外度过的时间比居住在新加坡 Australian researchers found that the sun is a key factor in preventing myopia in children. Dr. Ian Morgan of the Australian Center for Visual Science said the rate of myopia in East Asia has risen sharply over the past 30 years. The researchers compared children with Chinese ancestry living in Singapore and Sydney. The results showed that children living in Singapore had 10 times more myopia than children living in Sydney. However, children living in Sydney spent longer at eye-opening activities, taking twice as much books per week than children living in Singapore. However, their main difference is that Sydney kids spend more time outdoors on weekends than in Singapore
