With her eyes always feeling tired as she prepared for an exam, 16-year-old Sun Run went to the hospital with her parents in January. She was shocked when she found out that her eyesight dropped from 5.0 to 4.6. “A few of my friends have the same experience.” Sun said.
In fact, poor eyesight among Chinese students went up from 59.2% to 70.6% in the first six months of 2020, according to the Ministry of Education. By 2050, half of the world’s population will be nearsighted (近视), according to a study published in the journal Ophthalmology. The main reason for this is that people’s lifestyles have changed. They spend less time outdoors but more time looking at screens.
To protect students’ eyesight, the government has taken steps to protect students’ eyesight in China. In May 2020, the National Health Commission strongly required (要求) schools to make sure that students have at least two hours of outdoor activity a day. The Chinese government (政府) has worked out new requirements for school equipment that will take effect on March 1, 2022. For example, according to the requirements, the size of text in students’ textbooks should be no smaller than nine-point. Teachers should avoid (避免) teaching equipment that is too bright, Beijing Daily reported. There are also requirements for desk and classroom lights. For example, these lights should give off as little blue light as possible.
Blue light is bad for our eyes, because it can kill the photoreceptor cells (感光细胞) we need for our eyesight, according to Harvard Medical School. Many of the electronic devices we use every day, such as our phones and computer screens, give off blue light.
