a research shows. It challenges the old belief that short-sightedness is caused by computer use, watching
TV or reading in weak light.
The Australian scientists believe that sunlight is good for people's eyes. They did a research among 100
seven-year-old children in Singapore and Australia. According to the result, about 30% of the Singaporean
children were short-sighted while there were only 3% Australian children get short-sighted.
Both groups spent almost the same time reading, watching television and playing computer games.
However, the Australian children spent an average (平均) of two hours a day outdoors-90 minutes more
than the Singaporean children.
Professor (教授) 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 people gets larger. There're also
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 much brighter than indoor light. But why does playing outside stop us from becoming
short-sighted? Scientists believe that natural light has a special chemical (化学物质) which is good for our
eyeballs and stops people becoming short-sighted.
So go outdoors, It doesn't matter if that time is spent having a picnic or playing sports.
