Spend time in sunlight, avoid short sight
London, January 7: If you believe watching TV or computer is causing short sight in kids, you are wrong. An Australian study suggests that it is a lack of exposure to sunlight, rather than too much time spent watching TV and playing computer games, that damages children's eyesight.
Conducted by the Australia Research Council, the study suggests that children can avoid becoming shortsighted by spending a minimum of two to three hours in direct sunlight each day. The findings of this study contrast the widely accepted belief that watching TV, reading or playing computer games ruins vision.
The researchers behind the study-experts from the Australian National University and Sydney University-said that they even did not find any link between the flickering of TV and computer screens and damaged eyesight. They instead said that exposure to bright light could help regulate the eyeball's growth in childhood, dramatically reducing the risk of myopia.
During the study, the researchers compared the eyesight of young Chinese Australians and Singaporeans, and found that 30 per cent of six-year-olds in Singapore needed glasses, compared with three per cent of Chinese Australians.
The researchers revealed that both groups spent the same amount of time playing video games, reading and watching TV, but children in Singapore spent an average of 30 minutes each day outside, compared with two hours in Australia.
The figures remained similar even when the team compared children of Chinese descent from both nations, allowing researchers to eliminate ethnicity as a factor. Professor Ian Morgan, who led the study, said that shortsightedness was traditionally a problem among the highly educated who spent a lot of time indoors. "There's a driver for people to become myopic and that's education. And there's a brake on people becoming myopic and that's people going outside," the Telegraph quoted him as saying.

he
said
that
playing

had
the

effect
on
vision
as
reading,
using
the
computer
had
a
"neutral"
effect,
and
watching

He,
however,
cautioned
that
students
in

who
spend
a

should
be
aware
that
their
