Abstract: experts say that Asians have a high rate of myopia, and heredity is not the main reason. Compared with other Intercontinental countries, the population density in Asia is large, so the competition is more intense. Therefore, many Asian children carry out systematic reading too early when their eyes are still developing. The heavy learning pressure leads to a higher myopia rate in Asia. Recently, according to the latest research report of the World Health Organization, the proportion of myopia in China is as high as 47%. Like the United States, Japan, Singapore and Hong Kong and Taiwan, it is also the region with the highest prevalence of myopia in the world. Some studies have said that genetic genes determine that Asians are more prone to myopia. This report also shows that Asia accounts for four of the five high incidence areas of myopia. So, are Asians really more likely to suffer from myopia?, Objective reasons, genetic factors, different institutions have conducted sampling surveys among some Asian yellow people, some white people in Europe and America and some blacks in South Africa. The results show that under the same eye use, yellow people are most vulnerable to “myopia”, while white people have a significantly lower incidence of myopia, and black people are regarded as the most “afraid” of myopia among all races, Because their prevalence is very low. According to the current findings, many ophthalmology experts believe that this may be due to the sensitivity of yellow race to genetic susceptibility, namely genetic susceptibility. This conclusion is not absolute. At present, the pathogenesis of myopia is still unclear. Only from the analysis of sampling survey data, it is considered that yellow people should prevent myopia most., Competitive factors, experts say that Asians have a high rate of myopia, and heredity is not the main reason.

recently, the latest research report of the World Health Organization said that at present, the proportion of myopia in China is as high as 47%. Like the United States, Japan, Singapore and Hong Kong and Taiwan, it is the region with the highest prevalence of myopia in the world. Some studies have said that genetic genes determine that Asians are more prone to myopia. This report also shows that Asia accounts for four of the five high incidence areas of myopia. So, are Asians really more likely to suffer from myopia?
objective reasons
genetic factors
before, different institutions have conducted sampling surveys among some Asian yellow people, some white people in Europe and America and some blacks in South Africa. The results show that under the same eye use, yellow people are most vulnerable to “myopia”, while the incidence of myopia among white people is obviously low, Black people are regarded as the most “not afraid” of myopia among all races because their prevalence is very low. According to the findings of the survey, many ophthalmology experts believe that this may be due to the sensitivity of yellow race to genetic sensitivity. The conclusion of
and
is not absolute. At present, the pathogenesis of myopia is still unclear. Only from the analysis of sampling survey data, it is considered that yellow people should prevent myopia most.
competitive factors
experts say that Asians have a high rate of myopia, and heredity is not the main reason. Compared with other Intercontinental countries, the population density in Asia is large, so the competition is more intense. Therefore, many Asian children carry out systematic reading too early when their eyes are still developing. The heavy learning pressure leads to a higher myopia rate in Asia.
human reasons
dietary factors
nowadays, people’s increasingly refined high-carbon and low-fat diet leads to more and more sugar and less nutrients. As a result, the eyes “have more sugar and insufficient nutrition”. After the introduction of Western fast food such as KFC and McDonald’s into Asia, children’s intake of sugar is also increasing day by day: fast food everywhere, packaged food every day and sugary drinks.
take China as an example. Chinese people eat too many carbohydrates (sugar and starch) and are getting thinner and thinner. Before the 1970s, we ate coarse grain, standard powder in the 1980s, Fuqiang powder in the 1990s, and now we eat super refined powder. The increasingly refined high-carbon and low-fat diet makes most Chinese people increasingly lack eye nutrients such as vitamin A, selenium and DHA.
Lighting Factor
1 Lack of natural light
and
Australian scientists say that long-term study under indoor artificial light source will lead to eye elongation and induce myopia. Having 2 to 3 hours of outdoor activities and exposure to natural light every day can improve the dopamine level of the eyes and prevent eye elongation.
researchers found that those who spend a long time outdoors are much less likely to suffer from myopia.
2. Improper light intensity
some people think that when using electric lights, the brighter the light, the clearer they can see, which is actually wrong. Ophthalmologists believe that too much light can easily make the eyes tired. Therefore, when reading and writing at night, you can choose a lamp that can adjust the brightness to soft. Too strong or too weak light will cause damage to the eyes.
book paper and printing problems
more and more exquisite printing and more exquisite paper make books more and more ornamental. However, these exquisite books may also hurt your eyes. Coated paper is too reflective, especially at night, shaking your eyes. This dazzling light is called glare in medicine. It makes you less clear what you want to see and makes your eyes more tired. At the same time, in order to be beautiful, some books are not standardized in font color and size, which is also easy to cause damage to glasses and cause myopia.
misunderstanding of glasses
in fact, people always fall into a misunderstanding, that is, they should wear glasses once they are myopia, but myopia is also divided into pseudomyopia, true myopia and mixed myopia. Pseudomyopia, also known as adjustable myopia, can basically restore vision through adjustment, but many people wear glasses prematurely and lose the best recovery stage. At the same time, the degree of glassesUnreasonable matching also aggravates the degree of myopia.
and
teenagers have become people with high incidence of myopia.
and
in Asian countries such as China, Japan, South Korea and Singapore, the myopia rate of teenagers is more than 90%, while this proportion is only 20% to 30% in the UK. Statistics show that among the nine eye diseases endangering children under the age of 14, myopia ranks first. Some experts predict that myopia will become the second leading cause of blindness in the future.
through investigation, it is found that more than 70% of new cases of myopia occur in the stage of puberty. Except that some parents have the inheritance of high myopia, most teenagers and children suffer from myopia because of heavy schoolwork burden and addiction to electronic products. At the same time, the huge academic and competitive pressure makes teenagers spend too much time studying at their desks indoors, and they hardly have enough time to be exposed to natural light. In fact, the country with the highest myopia rate in Asia is also the country with the most eye-catching performance in education and studies.
myopia is the inevitable result of adapting to modern life.
in fact, myopia is a lifestyle related disease and an evolution of survival of the fittest adopted by human beings to adapt to modern lifestyle. In order to cope with close work, we must have good close reading ability, which is the result of the eye adapting to the environment. Eskimos are a typical example. In the past, they used to use their eyes from a distance and had no myopia at all. When modern civilization entered the Arctic Circle, Eskimos also appeared myopia. In fact, the prevention and treatment of
and
myopia is not difficult. At ordinary times, we should pay attention to eye hygiene, standardize the posture of reading and learning, give more time for eyes to rest, and often do eye exercises, which can reduce the incidence of myopia. At the same time, more outdoor sports and good living habits are also effective ways to prevent myopia. The number of ophthalmologists trained will increase greatly.
