Sunshine may prevent children from becoming short-sighted. A comparison of children of Chinese origin living in Singapore and Sydney found the rate of myopia in the Singaporeans was ten times higher. The key difference was that the Sydney kids spent almost four times longer outdoors.
The researchers say sunlight is the key - it increases dopamine levels which inhibits excessive eye growth, a known myopia cause.
Study co-author Dr. Kathy Rose still recommends sunglasses, as they don't seem to stop the dopamine release: "Protecting children's eyes from UV is the appropriate thing to do."
