Near-sightedness, or myopia, means nearby objects appear clearly, but those farther away look blurry.

The effect reverse myopia with sunlight

The rates of myopia have doubled, even tripled, in most of East Asia over the last 40 years, researchers say.And it’s a global issue — rates of myopia are also rising in Western nations like Germany and the United States。

But researchers say reducing risk of myopia is easy, free and readily-available: Get some sunlight。

The epidemic of myopia amongst East Asians has triggered cultural questions about why so many young people develop vision problems.Many have long believed that reading, studying or staring at your phone caused short-sightedness. And there’s the usual grumblings that young people spend way too much time glued to their screens。

But researchers are focusing on a different cause。

“If children get outside enough, it doesn’t matter how much they study they do. They don’t become myopic,” said Ian Morgan, researcher at Australian National University。

Researchers say kids and teens need to get sunlight during the critical years of their development while their eyeballs are still growing。

The solution is simple. Have kids “spend more time outside, have less demands (from) the schools and relax a bit,” said Seang Mei Saw, professor of epidemiology at the National University of Singapore。

To negotiate the expectations of parents and classes, researchers are experimenting ways to help students get increased exposure to sunlight。

One of the studies underway is the “bright light classroom” where the school’s walls and ceilings are made of see-through plastic that allows in light. Hundreds of students attend this unusual elementary school in Guangdong province。
