MANY children in Hong Kong wear glasses. Some do so because they cannot clearly see things that are far away. This condition is called myopia, or short-sightedness. People with myopia get a prescription from an eye doctor, then go to an optician to pick a frame and lenses.
Many children in Singapore (新加坡) have the same problem. Scientists there did a survey and found, on average, children become short-sighted at eight and a half years old. The study was conducted by eye experts.
To help prevent short-sightedness, parents should take their children outdoors more often. This is because our bodies make a special chemical called dopamine under the sun.
