Kids who spend more time outdoors have better vision(Agencies)

Updated: 2009-02-02 13:46 Comments(0) PrintMailFRIDAY, Jan. 30  -- Kids who spend more time outside -- and away from the television set -- are less likely to develop myopia, the inability to see things clearly at a distance.

The new report, from researchers in Boston, doesn't determine whether too much indoor activity actually causes poor eyesight. And even if it _______, researchers haven't pinpointed what the exact mechanism might be.

The study authors gave questionnaires to the parents of 191 children who were at _______ average age of 13.3 years. Among other things, the researchers asked about the children's time spent _______[use]  the computer, reading for pleasure and watching TV.

The children's eyesight was tested annually.

The findings were published in the January issue of Optometry and Vision Science.

The children who developed myopia -- also known as nearsightedness -- spent less time in outdoor activities, an average of 8.3 hours a week _______[compare] to 12.6 hours among the other children.

Those with myopia also _______ more television (12.5 hours vs. 8.4 hours a week).

Looking at things farther away may be another benefit of outdoor activities. "We know a great deal about what causes myopia in animals, including primates," said Howland. "Images that are focused behind the retina cause the eye to grow in length, making the animal more myopic. Generally speaking, one can prevent animals from becoming myopic _______ they are provided with sufficient opportunity to see distant objects."

In popular culture, bookworms and nerds are often depicted as wearing glasses. Some studies have indeed shown a connection _______ heavy reading and myopia, Gwiazda said. But the new research doesn't confirm that link.

"In our study, children with more hours of outdoor activity _______ not necessarily spend less time reading and using computers," Gwiazda said.
