With her eyes feeling increasingly tired and her vision blurry（视力模糊的），16-year-old Tian Ting 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 in only a term. "A few of my friends have had the same experience lately," Tian said.

In fact, poor eyesight among Chinese primary and high school students rose from 59.2 percent to 70.6 percent in the first six months of 2020, according to the Ministry of Education.

To protect students' eyesight, the Chinese government has worked out new requirements (要求) for school supplies (供应品) and equipments that will take effect (生效) 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 also try not to use projectors (投影仪) or other multimedia equipments (多媒体设备) that are too bright, Beijing Daily reported. There are also requirements for desks and classroom lights. For example, these lights should give off (散发) as little blue light as possible.

Blue light is bad for our eyes, as it can kill the photoreceptor cells (光感器细胞) we need for vision, according to Harvard Medical School. Many of the electronic devices we use every day, like our phones and computer screens, give off blue light.

Chinese government has also taken other steps to protect students' eyesight in China. In May 2020, the National Health Commission urged schools to make sure that students have at least two hours of outdoor activity a day.

Habits and field paths(小径)are formed in the same way: by repetition. Villagers, as a rule, do not purposefully make a foot path to the next village. They just go the shortest or easiest way over the fields. Day after day a people go and come the same way. Their feet beat the earth hard. By their repeated walking in the same direction a path is made. Similarly, the more often we do anything in the same way or at the same time, the more we shall do it that way. At last a habit is formed.

Usually it is much easier to form bad habits than good habits. The reason is simple – we are just lazy. For example, it is easier to lie in bed on a cold morning than to get up early. It is easier to put off today's duties to tomorrow than to do them at the right time.

Bad habits are not formed in a day, and it is the same with good habits. The forming of good habits needs time and calls for effort and hard work at first; but every time we do the right thing, it makes doing the same thing next time much easier. It's really hard to get up early on a cold winter morning for the first time. However, if you keep doing it every day for some time, it will become “a piece of cake” in the end. At last, we form the good habit ，which would be hard to break even if we wanted to break it.

Get into the habit of early rising, and you will not want to lie in bed like a lazybone. Get into the habit of telling the truth, and you will find it really hard to tell a lie. Get into the habit of doing today's work today, and you will feel uncomfortable if you have to put anything off till tomorrow.
