Children’s myopia is mostly due to “too strong light”!

Abstract: myopia is caused by many factors. The first is the popularity of electronic products in the information age. Entering the family classroom and filling every corner is harmful to our eyes; Second, the structure of diet is unbalanced., Myopia has become the “first killer” endangering eye health. The incidence rate of primary myopia in China is second, and the prevalence rate of myopia among Chinese primary school students has reached nearly 40%, and the myopia rate of high school students is nearly 70%, according to the survey. Now the proportion of children with myopia is also increasing. When they enter the campus, only a few students do not wear glasses., Myopia is caused by many factors. The first is the popularity of electronic products in the information age. Entering the family classroom and filling every corner is harmful to our eyes; Second, the structure of diet is unbalanced. The nutrition intake is not healthy and comprehensive; Third, genetic factors. If there are congenital genetic conditions, in the process of children growing up, the acquired factors will add up to the problem of myopia; Then there is the problem of light pollution. Learning, living and activities are everywhere, which directly leads to the deepening of students’ myopia, even adults will lead to visual fatigue, and the elderly will lead to organic diseases such as dry eye, cataract and retinal degeneration., Too bright light induces children’s myopia. The use of light is also moderate. The stimulation of strong light to the eyes is very serious. All objects seen by the eyes are felt in the form of light. The eyes have a self-protection ability. Under normal light intensity, the eyes are very comfortable. When the light is dark, the pupil is enlarged. For example, when reading under candlelight or kerosene lamp or even moonlight in the past, myopia is not easy to form. Now the light is too strong, the pupil is reduced, and the lens expands because it is elastic. If it is in this state for a long time, it will be shaped over time, and myopia will slowly form or deepen. From dark places to strong places, the pupil shrinks sharply, causing ciliary muscle spasm, which also has a great impact on the eyes., There are many table lamps on the market. It is best to choose eye protection lamps. Whether they are eye protection lamps depends on whether they are continuous light sources. The eyes feel very comfortable with continuous light sources. Many fluorescent lamps are stroboscopic light sources. The eyes can’t feel stroboscopic light sources above 40Hz, but eye fatigue will occur over time. Therefore, when selecting table lamp, it is best to use 40W incandescent lamp with tungsten filament light., Many parents and friends asked that there are too many books at home. They decided to read e-books, which is convenient and saves space. Reading also needs to find the feeling of reading. The feeling of turning books is that e-books can’t give. Second, paper books are much less harmful to their eyes than e-books seen through electronic screens. Long term use of electronic screen radiation and light damage to the eyes is very serious. Including students doing homework and reading with iPad. From the doctor’s point of view, we don’t recommend reading e-books., The first visual examination should be carried out at the age of 3-4.

myopia has become the “first killer” endangering eye health. The incidence rate of primary myopia in China is second, and the prevalence rate of myopia among Chinese primary school students has reached nearly 40%, and the myopia rate of high school students is nearly 70%, according to the survey. Now the proportion of children with myopia is also increasing. When they enter the campus, there are only a few students without glasses.

The nutrition intake is not healthy and comprehensive; Third, genetic factors. If there are congenital genetic conditions, in the process of children growing up, the acquired factors will add up to the problem of myopia; Then there is the problem of light pollution. The places where learning, living and activities are located are everywhere, which directly leads to the deepening of students’ myopia. Even adults will lead to visual fatigue. For the elderly, it will lead to organic diseases such as dry eye, cataract and retinal degeneration. Too bright

and

light can induce myopia in children. The use of

and

light is also moderate, and strong light can cause serious eye irritation. All objects seen by the eyes are felt in the form of light. The eyes have a self-protection ability. Under normal light intensity, the eyes are very comfortable. When the light is dark, the pupil is enlarged.

the first visual examination should be carried out at the age of 3-4. The myopia of

is getting earlier and earlier. Is there any way to make the myopia not so early, or what is the law of the development of children’s vision? The formation of

and

myopia is divided into two parts. One part is related to congenital conditions. For example, the ocular axis is relatively long at birth, that is, the ocular axis is too long caused by embryonic development and genetic factors. These two are congenital. Related to acquired factors, including excessive regulation caused by unsanitary use of eyes, eye fatigue and unbalanced diet. Congenital conditions and acquired factors together form the true degree of myopia. Congenital myopia is usually called axial myopia and can be corrected by surgery. The influence caused by acquired factors can be prevented
