Research reveals link between environmental factors and rising cases of myopia

Children should be encouraged to spend time outdoors to reduce their risk of becoming shortsighted, experts have said.

Shortsightedness is rising around the world, with the condition said to have reached epidemic proportions in east Asia: estimates suggest about 90% of teenagers and young adults in China have the condition.

While genetics are thought to play a large role in who ends up shortsighted – a condition that is down to having an overly long eyeball – research also suggests environmental factors are important.
