Sunlight could stop short-sightedness

"Australian scientists from The Vision Centre say there is persuasive evidence that increased exposure to daylight can prevent the permanent short-sightedness and eye damage which now afflicts up to 80-90 per cent of children in cities in East Asia such as Singapore and Hong Kong.

The finding demolishes long-held beliefs that short sight is due mainly to reading, and overuse of TVs and computers by youngsters, or is primarily linked to genetic factors. Myopia affects over 1.6 billion people worldwide, is spreading rapidly among city populations and, in its most severe form, can cause blindness by middle-age."
