Time outside may help prevent myopia in children

A new Australian study found that children who spent the most time outdoors were the least likely to suffer from myopia, which is also known as near-sightedness.

Researchers say it does not matter whether the child is playing a sport or just reading a book.

Experts have yet to determine why being outside is protective, but they believe a likely candidate is the high levels of light experience outside compared to inside.

The study looked at more than 1,700 6 year olds and more than 2,300 12 year olds.
