A University of Cambridge study has shown that kids who spend more time outdoors are less likely to become nearsighted, according to the Telegraph newspaper.

Thes study showed that nearsighted children spend, on average, 3.7 hours per week less in natural light than children who are not nearsighted.

The UK Press Association reported the study said the difference had to do simply with being outdoors in natural lights, not with the activiities kids do if they spend more time inside, like watching television of playing video games.

Increasing children's outdoor time could be a simple and cost-effective measure with important benefits for their vision and general health, said Anthony Khawaja of Cambridge, according to the UKPA.
