According to the report of China Youth Daily, ophthalmologists are worried about the current situation of vision development of teenagers in China. According to the statistics of relevant experts, up to 90% of college students in China are nearsighted, and 20% of young people aged 20-30 suffer from high myopia.
Experts believe that, generally speaking, a considerable part of high myopia develops into pathological myopia after middle age. At present, the prevalence of pathological myopia is about 1% to 2% of the population, and there are at least100000 patients in China, which is one of the common causes of blindness in adults. However, the parents of most young students do not attach importance to this point.
Among East Asian people who highly advocate learning, children have the highest myopia rate.
According to the research report, in East Asia, 96% of young people in South Korea suffer from myopia, while 85% in Taiwan Province Province of China and 82% in Singapore.
These areas with high myopia rate are called "East Asians who love learning". With the rapid development of society, people are now living in a fast-paced life, not only adults, but also teenagers.
Experts believe that the culprit of the sharp increase in myopia rate is no longer genetic factors. One is the continuous study pressure, and the other is the excessive use of electronic products such as mobile phones and tablets. Statistics show that in the 1960s, only 20% of China people suffered from myopia. Today, the myopia rate in China is expected to double.
Due to the pressure of social competition, many parents don't want their children to lose at the starting line. Since children are still in kindergarten, they have been developing their early intelligence. Children are overwhelmed by various early education courses, such as music, dance, English, Chinese and arithmetic. Studying in kindergarten, attending remedial classes outside, and finally popularizing common sense at home.
Busy laying a good foundation for children's future life, but also ignoring the need for children to get in touch with nature and need appropriate outdoor sports. Outdoor sports can exercise physical fitness, and exposure to natural light is also a good way to protect your eyes.
Otherwise, there were scholars in ancient times, and the ancients loved learning as much as our children now. I haven't seen a child with yellow mouth who became "four eyes" when he was a child. Although there were few people with myopia in ancient times, it was not absolute. The picture below shows a part of the landscape volume of Du Nan Fan Hui written by Qiu Ying in Ming and Qing Dynasties. It describes in detail the life of Nanjing citizens during Yongle period of Ming Dynasty. Take a closer look at the old man under the sign "Redeem Golden Beads" in the lower right corner. If you look carefully, you will find an old man with glasses.
Besides, there is a jingle in the Ming Dynasty that describes myopia.
Xiao Jun's eyes are so strange. Who are Gigi Lai's supporters? The sun shone marbles through the window lattice, and the moon moved to pick up sticks. I'm black and blue because I look at the painted wall, and I twist my eyebrows because I lock the book. It's even more ridiculous. Blowing a lamp will burn the skin of your lips.
This poem vividly describes myopia. So what were the ancient glasses like?

In fact, myopia can also be regarded as a kind of "rich disease" in ancient times, but it is not so common in modern life.
Because although ancient literati were famous, few people could really afford to read books, only those with scholarly family or good family conditions could afford to read books. Therefore, myopia is almost exclusive to ancient literati. Moreover, life in ancient times was not as rich as that in modern times. Modern people can play mobile phones, watch TV and play games online to kill time. Ancient people often went outdoors, rode horses, shot arrows and traveled around the world. Such outdoor activities are conducive to the relaxation of eye muscles, so they protect the eyes. On the other hand, modern life, whether it is study, work or leisure time, has been inseparable from electronic equipment. "Low-headed people" can be seen everywhere. In the face of these electronic devices, the biggest harm is the eyes. Therefore, no matter how busy your life is, you should also pay attention to protecting your eyes. If you are tired from work, go and see the distance. Parents should not let their children study for a long time and ignore the health of their eyes, nor should they immerse themselves in electronic devices for a long time.
