Why are nearly half of Chinese people nearsighted?

The world health organization's latest study says the number of people with myopia in China is up to 600 million, almost half the total population of China, according to a report by China radio central news. The myopia rate of high school students and college students in our country is more than 70%, and the rate of myopia is increasing year by year. In comparison, the myopia rate of primary and middle school students in the United States is only 10%.
Why Chinese myopia is so high? Some people say that Chinese eyes are too busy! We are in a screen age, from birth to old age, cheap nfl jerseysfrom day to night, except for eight hours of sleep, with the eyes almost inseparable from the screen. On the bus, I watch my cell phone, watch my computer at work, watch TV after I go home, and even play games or brush on my mobile phone before going to bed at night.
But also is a student, Chinese pupils myopia rate is over 30%, while European and American countries of pupils myopia rate is only about 10%, compared to Chinese high school students more than 80% of the rate of myopia, Europe and the United States high school students about 40% of the rate of myopia is the level of primary and middle school students. Why is that?
To analyze the causes, students bear the brunt of the burden. The cause of myopia is simple, which is the fatigue caused by overloading of the eye. From primary school to high school, students' homework is 12 years, far superior to the ancient "decade cold window". Every student, most of the students wear a pair of glasses that will never be picked.
In recent years, science has found that the most important reason for myopia is the lack of time to participate in outdoor sports. Outdoor lighting can help the retina release a chemical to slow the growth of the axial length of the eye, and if it's long enough to read and not go out, it can exacerbate myopia. However, Chinese children do not value outdoor activities, and Chinese students are taking a nap when they are free at noon. They also have a mountain of homework to take home. In addition to studying at school and a few hours of tutoring on weekends, it is common for Chinese children to study four hours a day at home. As a result, as high as high school, up to 90% of Chinese urban youth are short-sighted, about three times the rate of myopia in the United States. Even more worrying is the severity of myopia in Chinese children, with 10 to 20 percent of children with myopia expected to develop high myopia.
Europe and the United States and our country's education environment, there are huge differences in our kids even in utero, from the mother's belly start to kindergarten, primary school, middle school to high school, in order to lead the university entrance exam that root easily, and even take part in different kinds of study and training and it is this "education model" business before pleasure, among children in primary and secondary schools in myopia. While the European and American countries, in contrast to the us, children from the beginning of the play, primary school junior high school of learning pressure is not big, but from high school to university after learning pressure increased gradually, entered the university after the child's body has gradually mature, and the chance of myopia is greatly reduced.
Of course, it can't be said that school doesn't pay attention to students' eyesight. In 2007, for example, the ministry of education asked schools to increase physical education classes to combat obesity and visual impairment, but many teachers and parents resisted. Because in their opinion, the children are the first and the first. For example, every day on campus regularly do eye exercises, many school tables and chairs have been replaced by adjustable height, every semester physical examination must have visual inspection. However, the result of the examination is nothing more than a notice to the book, with a leaflet on how to prevent myopia, which will have the address of the treatment agency. Over the year, more and more students are myopic. You're welcome to say that the current education system is exhausting the children's supposed bright eyes.
And to cultivate the students' children, and we Chinese people are the essential difference is the European and American countries, Cheap wholesale jerseysin Europe and the United States, parents cultivate children's goal is to cultivate children's independent ability to survive, and the parents of our country is the child as "pet", wish all day in her arms, held in the hand. In addition to learning, even the kids clothes dirty feeling the pinch, makes children less outdoor activities, curtilage more time indoors, playing computer, mobile phones and other electronic products, thus increasing the risk of myopia.
In contrast, children have lost their own happy childhood. Under the weight of the glasses, the children can only bury their heads deeper, and we are accustomed to praise them as "hard work". But, according to the Chinese proverb "young don't work hard, idle young, needy old", "s person of bitterness," such as the theory, the poetic childhood lost of young students, now should also have a poetic life of their own, but the reality is that after the first to enter the "30" 80 teenagers, but is still a "no room no car", become the most in the city of culture and education "ant tribe" - this is really a wonderful irony.
