Abstract: what worries parents most is to equip myopia children with glasses. Many parents have many misunderstandings about glasses, such as mild myopia without wearing glasses for a long time., According to statistics, there are nearly 400 million people with myopia in China, of which 270 million are teenagers, including 30 million with high myopia. The incidence rate of incidence rate of myopia is about 6%. The incidence of myopia in ancient Chinese literature search is the highest in the world. The incidence of myopia is 50% to 60% in the world. The incidence of myopia is 50%. The incidence rate of myopia is about 31% primary school students, about 58% of middle school students, 76% of high school students, and 82% of college students. Not only that, the average degree of myopia will increase by 125 degrees every year., How does myopia happen? This is also a question that many parents doubt. Experts explained that myopia has a certain genetic tendency, especially for high myopia. Especially high myopia, which belongs to autosomal recessive inheritance. At the same time, development can also lead to myopia. The baby’s eyeball is small, but with the growth of age, the eye axis also gradually lengthens, and the development is normal until adolescence. If it is over developed, it will lead to myopia., In terms of external factors, unbalanced nutrition, too little outdoor exercise and too long eye use will also lead to myopia. In addition, the distance between the eyes is too close and the writing posture is incorrect, which makes the eye muscles unable to flex flexibly, resulting in the strengthening of the convergence effect, so that the extraocular muscles exert pressure on the eyeball, the intraocular pressure increases, the intraocular tissue is congested, and the front and rear axes of the eyeball become longer, forming axial myopia., In addition, many parents have many misunderstandings about glasses, such as mild myopia without wearing glasses for a long time. If the binocular vision is more than 0.7, you can use your eyes close without glasses. However, as long as the binocular vision is less than 0.7 or more than 200 degrees, myopia patients need to wear glasses for a long time. If the visual acuity of the two eyes is very different, it will deepen the degree of myopia without glasses., Some parents believe that the low degree of glasses can prevent progress, which is purely psychological comfort. If the child’s myopia is found and not corrected in time, the child’s myopia rate will increase by about 100 degrees per year. Wearing glasses of inappropriate degrees, the child’s myopia rate will increase by about 50 degrees per year. Therefore, the glasses should be accurate. If the degree is too high, it belongs to “over correction”, which may lead to children’s dizziness after wearing glasses; With a low degree of “leave room”, myopia may be further deepened., When parents match their children’s glasses, they must start with the lens quality and choose the lenses suitable for their children in many ways, so as to achieve good correction effect.,
