For a long time, scientists thought myopia was primarily determined by our genes. But about 10 years ago, it became clear that the way children were growing up was harming their eyesight, too. The effect is starkest in east Asia, where myopia has always been more common, but the rate of increase has been uniform, more or less, across the world. In the 1950s, between 10% and 20% of Chinese people were shortsighted. Now, among teenagers and young adults, the proportion is more like 90%. In Seoul, 95% of 19-year-old men are myopic, many of them severely, and at risk of blindness later in life.
