Abstract: Children’s myopia not only affects the appearance and the quality of life and learning, but also will be limited in the future study, job selection, joining the army, employment in special industries and so on. In addition, the cost of matching glasses in China is more than 10 billion every year. If the same cost is used for more purposes such as improving health and medical care, it can greatly ensure people’s quality of life.
often hear many parents say that their children seem to be nearsighted, and some parents say that their children’s nearsightedness is longer. When the winter vacation meets the Spring Festival, children not only have to play games and watch TV, but also have to put the protection of children’s eyes and pay attention to work on the agenda during the winter vacation.
what harm does myopia have in children?
children’s myopia will not only affect the appearance and the quality of life and learning, but also be limited in the future enrollment, job selection, joining the army and employment in special industries. In addition, the cost of matching glasses in China is more than 10 billion every year. If the same cost is used for more purposes such as improving health and medical care, it can greatly ensure people’s quality of life. In addition, with the growth of people’s age, high myopia will produce a series of complications, such as high myopia complicated with cataract, the proportion of glaucoma in high myopia is higher than that in normal people, fundus lesions of high myopia and so on. Among them, high myopia and low vision are closely related. Retinal detachment, neovascularization and macular hemorrhage caused by serious fundus complications of high myopia will lead to unrecoverable blindness, which will have a great impact on life and vision. What are the causes of
myopia? One of the most well-known causes of
myopia is heredity, that is, if fathers and mothers are myopic, the proportion of their children who are myopic will increase significantly. Now more studies have shown that, in addition to genetic factors, environmental factors are the more important factors in the cause of myopia. This includes four aspects: first, the increase of close working hours, that is, spend a lot of time reading books and newspapers and staring at the screen of electronic products every day. Second, lack of nutrition, that is, an unbalanced diet. Children with myopia usually eat less vegetables and fruits, but a lot of sweets, which will increase the degree of myopia. Third, the reduction of outdoor activities, which is now recognized as an important environmental factor to accelerate the development of myopia. Now most children have less and less time for outdoor activities due to excessive educational pressure and enhanced learning competition, and myopia will become more and more serious. Fourth, improper glasses. When children have myopia, if they do not match glasses in time or glasses are inappropriate, it will also accelerate the development of myopia. An inappropriate pair of glasses is like putting a pair of unfit shoes on a child, which will also have an impact on the child’s health.
got myopia how to treat?
when parents suspect that their children have myopia, they should first go to an authoritative hospital for professional medical examination. If the child is diagnosed with “pseudomyopia”, that is, it has not developed to the stage of true myopia, you can choose not to wear glasses, but you must let the child’s eyes rest for a long time. If it has developed into “true myopia”, that is, the child can’t see clearly, it must be corrected as soon as possible, otherwise it will accelerate the development of myopia.
are aimed at people of different ages and degrees of myopia. The correction methods are also divided into three types, namely frame glasses, corneal shaping glasses and refractive correction.
what is the use of wearing frame glasses?
when myopia develops to a certain extent, they all need to wear glasses to improve their eyesight. If the degree of myopia exceeds 100 degrees, you should wear glasses to correct it; If the degree of myopia exceeds 300 degrees, in addition to rest time, you should wear glasses all day. You need to wear glasses when you are watching blackboard in class, outdoor sports, or reading and writing at home.
need to go to the hospital for optometry review every six months after wearing frame glasses, mainly to see whether the diopter has changed and whether the glasses currently worn are appropriate. It’s like a child’s body is developing every year, so clothes and shoes need to be changed every year. The eyes are the same. The eyeballs are also growing with the development of the body. If the degree of glasses does not keep up with the growth of eyeballs, it will lead to the decline of vision. But in fact, because physical development is inevitable, it is difficult to control the growth of myopia at present, but it can slow down the growth rate, so as to avoid children becoming highly myopia. Is
corneal shaping lens really good for the treatment of myopia?
corneal shaping lens is a very effective way to prevent and control myopia, which can greatly delay the development of myopia. In fact, the corneal shaping lens is a kind of rigid contact lens, which is pressed on the cornea. In the normal blinking process, the eyelid transmits pressure to the cornea through the corneal shaping lens. This mechanical physical stimulation will redistribute the corneal epithelium, so as to change the central area of the cornea, so that the light can accurately fall on the retina after focusing on the eyeball, Form a clear image. Corneal shaping glasses are safe for children. They are generally required to be worn over the age of 8. The materials of shaping glasses at different prices are also slightly different, which can be selected in combination with their own economic situation.
corneal shaping lenses belong to three types of medical devices. This contact therapeutic lens is not suitable for all eyes. If you want to wear corneal shaping lenses, you must go to the standard ophthalmology for professional examination. Through the instrument, check the corneal radian, the size of corneal membrane diameter, and whether there are eye surface diseases that affect the wearing of corneal shaping lenses, Strict fitting is also required. After wearing the corneal shaping lens, the doctor should observe whether the mobility and tightness are appropriate. Is the therapeutic effect of
refractive surgery good?
at present, the common refractive surgery include excimer laser surgery, femtosecond laser surgery and intraocular lens implantation for high myopia. Similarly, refractive surgery is not suitable for everyone. Only people over the age of 18 with stable myopia can do refractive surgery, so the prevention and control of myopia should be started from an early age.
