英国剑桥大学的科学家最近提交给美国眼科学会的一项研究说,儿童每周在户外多活动1个小时,可以减少2%患近视的几率。该研究囊括1.04万名儿童,结果显示,和正常视力或远视的儿童相比,近视儿童一周花在户外的时间平均要少3.7个小时。 A recent study submitted to the American Academy of Ophthalmology by scientists at the University of Cambridge in the United Kingdom said children who spend more than an hour outdoors each week can reduce their chance of developing myopia by 2%. The study, which included 10,400 children, showed that myopic children spent an average of 3.7 hours less per week on average than children with normal vision or hyperopia.
