Lifestyle makes myopia less common

Abstract: at present, there are more than 400 million myopia patients in China, among which teenagers have become the “hardest hit area”: the myopia rate of primary school students is more than 30%, that of middle school students is 70%, and that of college students is 90%. Jinshi in this world are all short-sighted. It’s a prophecy!, It is said that Ouyang Xiu and Su Shi, the great writers of the Song Dynasty, were short-sighted. In the Ming Dynasty, someone wrote a poem mocking shortsightedness: “Xiao Jun’s eyes are so strange that he stood next to him and asked who is it? The sun went through the window lattice to take marbles, the moon moved the shadow of flowers to pick up firewood. He scratched his nose by looking at the painting wall and clamped his eyebrows to lock the bookcase. There are even more places where he can laugh, blowing a lamp and burning his lips.”, In the Qing Dynasty, riding and archery were the skills of watching the family, so riding and archery became an important part of the national examination. According to the records of the Qing Dynasty and the Qianlong Dynasty, there are more than 120 examiners today, and there are more than 70 people who report myopia. Emperor Qianlong clearly observed that because they can’t ride and shoot, they use myopia as an excuse., There were few myopia in ancient times. Xiaolin Guangji included many jokes to ridicule myopia. It is because there are few people that they are laughed at. Why was myopia less in ancient times? First, there were few literate people in ancient times, which determined that there was no environment for myopia in ancient times, and the risk and probability of myopia were very low. Second, the ancients mostly used natural light sources for reading, and few people lit lights to boil oil at night. Third, the ancients used a long brush to write, their eyes were far away from the words, and their words were relatively large, which objectively played a preventive role., Even after the founding of new China, there are still few people with myopia. In 1956, the Party Central Committee put forward the prevention and treatment index to ensure the health of working people, among which the important task of prevention and treatment for ophthalmology is trachoma. An old teacher recalled that during the “Cultural Revolution” period, people had bright eyes when they didn’t read or study. When the college entrance examination was restored, some students used their eyes too much and began to be short-sighted. In the 1960s and 1970s, the myopia rate of children in China accounted for 15% to 20%, which has been on the rise. The state began to carry out eye exercises during recess. “Eye exercises began to protect eyesight and prevent myopia for the revolution…” has become the memory of a generation., The author belongs to the post-80s generation. When I was in primary and junior high school in the 1990s, myopia was still a minority. Anyone who wanted to wear a pair of glasses would be nicknamed “small four eyes”., The latest survey by the Ministry of education and the national health and Family Planning Commission shows that at present, there are more than 400 million myopia patients in China, of which teenagers have become the “hardest hit area”: the myopia rate of primary school students is more than 30%, middle school students is 70%, and college students are 90%, rising rapidly. Jinshi in this world are all short-sighted. It’s a prophecy!, The main reason for the rise of juvenile myopia is related to the examination oriented education system. Long time close reading and unhealthy eye use make the eyes very tired. Due to the popularity of electricity, the opportunity to use eyes at night has increased significantly, and the sleep time is very late. In the 1970s, people often rested after dark. In addition, artificial light such as mobile phone screen, display and projection lamp have an impact on vision. From an evolutionary point of view, human eyes adapt to the natural light illuminated by the sun. Myopia is caused by congenital genetic factors and acquired environmental factors. For Chinese people, the gene is still that gene, but the environment has changed too much!,
