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.

Different from common belief, blue light may not have a strong negative effect as people thought-according to the scientists from the University of Manchester.
It's known that our body clock measures brightness through melanopsin( 黑素蛋白 ) , a specialized light sensitive protein in the eye. So there has been lots of interest in studying the influence of light on the body clock. Researchers changed the make-up of short and long wavelength light, which provided a small difference in brightness, as well as changes in color. Findings suggested blue light might be troublesome to our sleep patterns.
The new research, however, used a different method, since the changes in color may oppose the benefits from reducing the brightness signals detected( 探测 )by melanopsin. The team used specially designed lighting to change color without changing brightness.
Findings of the new research showed that blue colors produced weaker effects on the subjects' body clock than equally bright yellow colors. "Our recognition of color comes from the retinal cone cells( 视网膜锥形细胞 ) , and the blue color signals they supply reduce the influence of light on the body clock," explained the lead researcher. "The research shows the common view that blue light has the strongest effect on the body clock is misguided.”
According to the team, using dim( 昏暗的 ) , cooler lights in the evening and bright warmer lights during the day may be more beneficial to ensure healthy patterns of sleep. Twilight( 暮光 )is both dimmer and bluer than daylight and the body clock uses both of those features to decide on the proper times to be asleep and awake.
The findings have important suggestions for the design of lighting and visual displays which aim to promote people's sleep patterns. Present technologies are mostly designed to limit our evening exposure to blue light by changing the screen color of mobile devices. The technology, however, may send the body clock mixed messages. This is because the small changes in brightness they produce come along with colors that are commonly seen during the day. So there's more for the designers to take into consideration.
Setting our body clocks in line with our social and work schedules can be good for our health, and using color correctly could be a way to help us better achieve that.
1 . The writer mentions different research methods in Paragraph 2 and 3 to________.
A . suggest how the data of the research should be collected
B . explain why the findings of the old research are reasonable
C . discuss possible ways of studying the influence of blue light
D . show the progress in the methods used in the studies of blue light
2 . According to the new findings, what should the designers take into consideration?
A . The changes in both colors and brightness.
B . The influence of the daylight on sleep patterns.
C . The suggestions on the proper use of mobile devices.
D . The balance between technologies and the body clock.
3 . What can we learn from the new research?
A . Blue light cannot he easily detected by the body clock.
B . Blue light has the weakest effect on people's body clock.
C . Blue light is not as harmful to their sleep patterns as people thought.
D . Blue light benefits people more in their sleep patterns than yellow light.
