5.The strong emphasis on educational achievement in China,Japan and other parts of South-East Asia may be coming at a heavy price.Researchers say that hard work at school plus the lack of exposure to outdoor light is damaging the eyes of almost nine out of ten students-with one in five at serious risk of visual impairment and blindness.The scientists say that young people need up to three hours a day of outdoor light,but many infants are also missing out as they nap during lunch time.Dr.Ian Morgan is the lead author of the study."I think what's happened in South-East Asia is that we've got a double whammy.We've got the massive educational pressures and we've got the construction of a child's day in a way that really minimises the amount of time they spend outside in bright light."
The scientists say that genetic factors,long thought to play a big role in short-sightedness,are not as important as the environment.They point to Singapore as a place with several different racial groups,all of whom are now suffering high levels of short-sightedness.
The authors suggest that compulsory time outdoors should be considered by educational authorities across South-East Asia as a way of dealing with the problem.
