Children who play outdoors are less likely to have to wear glasses later in life.
British researchers found children who spend a lot of time outdoors were almost 50% less likely to be short-sighted when they were 15 compared with those who remained inside as children.
Some 14,000 eight- and nine-year-olds were studied for the research. The results showed time spent outdoors was a more important obstacle of myopia (short sightedness) than being physically active — but they are still unsure why.
