Spending two or three hours playing outdoors each day can reduce(減少)a child’s chance of becoming short-sighted(近視),research shows . It challenges the belif that short-sightedness is caused by computer use , watching TV or reading in weak light .
Australian government researchers believe that sunlight is good for people’s eyes . They compared the vision (視力)and habits of 100 seven-year-old children in China and Australia .In all,30% of the Chinese children were short-sighted .This percentage was ten times higher than Australian children.
Both groups spent a similar amount of time reading, watching TV and playing computer games .However , the Australia children spent an average of two hours a day outdoors ,90 minutes more than the Chinese children.
Professor Ian Morgan said ,“Humans are naturally long-sighted ,but when people begin to go to school and spend little or no time outdoors ,the number of short-sighted peoplegets larger. We are also seeing more and more short-sighted children in cities all around the world –and the main reason may be that city children spend less time outdoors .
Daylight can be hundreds of times brighter than indoor light . But why does playing outside prevent us from becoming short-sighted ? Scientists believe that natural light has a special chemical(化學(xué)物質(zhì))which stops the eyeball from growing out of shape and prevents people from becoming short-sighted .
So go outdoors .It doesn’t matter if that time is spent having a picnic or playing sports .
