Inadvertently, there are many kinds of short-sighted glasses in the glasses shop on the street, such as ultra-thin, plexiglass, resin, frameless and invisible. The popularity of the glasses business is enough to see the number of short-sighted people. Take a look at the location of these optical stores, near the middle school, next to the University, in the book city Most of them are concentrated in places where teenagers live in groups.
Children are nearsighted. It is common for some people to wear glasses when they are nearsighted. But when they find that they are nearsighted, they should put glasses on their shelves. They don't know if they don't ask. They scare the reporters when they ask, because they don't get an answer from the ophthalmologists.
One of the expert opinions: it is better to wear glasses for true myopia
"From a medical point of view, as long as it's true myopia, it's better to wear glasses." Qi Ying, chief physician of the eye optometry center of Beijing Tongren Hospital, said this. She explained to our reporter that the earlier the onset of myopia, the less stereotyped the child's vision. If his vision is in the abnormal vision state of 0.5-0.6 and he does not wear glasses, he will often squint his eyes to improve his vision; if he overuses his eyes for a long time, the degree of myopia will deepen, and the retina system will not be stimulated by normal vision for a long time, and amblyopia may form in the future. Once amblyopia is formed, it is difficult to correct the vision to normal vision (1.0).
Qi also stressed: "as long as there are degrees after mydriatic optometry and the vision is less than 1.0, it is better to wear glasses, but the degree should not be too large. For example, the degree of optometry is 1.50D (150 degrees), the child can see 1.5, but 1.00d (100 degrees) can see 1.0, it is OK to wear 100D glasses for him, the child can accept and will not affect the normal development of the retina. "
"If the degree of myopia is less than 100 degrees after mydriasis, such as 50 or 70 degrees, and the vision may be within the normal vision range (0.8-1.0), the child can adjust and relax his eyes properly. If the adjustment is effective, the child can not wear glasses for a short time. However, after three months to one year's observation, the eyesight hasn't recovered, or it's more difficult to see, so you should wear glasses. "
When the reporter asked whether wearing glasses would deepen the degree, Dr. Qi said, "the deepening degree is not necessarily related to wearing glasses, but mainly related to using eyes. One is related to overuse of eyes, the other is related to the age of myopia. The student stage is basically in a period of physical development, coupled with the heavy burden of learning, using too much eyes, myopia also develops. "
Expert opinion 2: don't wear glasses easily
However, not all ophthalmologists agree that children wear glasses as soon as they are nearsighted. Liu Yuqi, an ophthalmologist who has been engaged in ophthalmic treatment for nearly 40 years in Shouren ophthalmic clinic in Beijing, thinks that whether children need to wear glasses for myopia depends on the specific situation.
Just at the weekend, the reporter saw many 10-year-old children and their parents gathered in the outpatient department, and chatted with them by the way: Tong cilia, a beautiful little girl, 8 years old this year, the third grade of primary school, just found that the eyesight decreased during the school physical examination this year.
According to Tong's father, "myopia was 50 degrees, but during the SARS period, the school was off. The child watched TV at home all day, and the degree suddenly increased to 125 degrees." "I'm short-sighted at such a young age. What can I do if I want to study and work in the future? Our parents are very distressed, but they don't want her to wear glasses..." They heard that Dr. Liu here can treat myopia without wearing glasses, so they came here. After several treatments, children's eyelashes are now 75 degrees.
According to Director Liu, "wearing glasses doesn't solve two fundamental problems: one is the problem of always looking close, children in the city don't have the chance to look far; the other is the weakness of ciliary muscle regulation."
At present, there are many misunderstandings in children's wearing glasses. First, children are nearsighted and highly myopic above 300 degrees. If they don't wear glasses, children will squint, resulting in blurred vision. There is no clear visual stimulation and excited state in the retina system, which will affect the development of the retina and cause amblyopia. In this way, even if the vision is corrected, the effect is not good;
Another mistake is that children always look close when they wear glasses, because the media for acquiring knowledge is still very close to them. In this case, the degree of myopia will inevitably deepen. Nearsightedness is the blurring of the distance and the clarity of the near. Generally speaking, you can see objects 5 meters away when you wear glasses. The degree that should be far is always near, and the degree of the glasses must also increase.
Eyeball is a terminal organ of human blood vessels and nerves. Chinese medicine pays attention to "invigorating the spleen and nourishing blood" in the treatment of myopia. Children's absorption capacity of spleen and stomach is strong, and there are more nutrients in the blood. Director Liu's principle of treatment is that he can reasonably adjust the spleen and stomach according to the principle of "blood and sperm, and then concentrate on the eye", so that the child can absorb the function and increase the nutrition in the blood so as to put the essence in the eye.
If the eyes develop well, the vision system will be healthier and the ability to see far will be stronger. In addition to acupuncture treatment and traditional Chinese medicine conditioning, under this dynamic treatment, myopia can be prevented.
Why does myopia rate stay high?
According to a ancient Chinese literature search released by the Ministry of health and the Ministry of education, the incidence rate of myopia in China is nearly 60%, ranking only second in the world after Japan. The number of patients is over 60 million, ranking the highest in the world. At present, the myopia rate of primary and secondary school students in China has reached 34.6%, and that of senior high school students has reached 70%. The reasons for the high myopia can not be ignored.
Qi, an ophthalmologist at Tongren Hospital, pointed out that in addition to genetic factors, most modern children's myopia is caused by the environmental pressure of "looking forward to success". "Nowadays, children have a heavy burden of learning. In addition to a five-day class, parents will arrange extra homework for their children on weekends. Moreover, with the higher grade, the heavier the burden of learning, the children do not have enough time for outdoor activities.
Director Liu Yuqi also has original views on this issue. She believes that modern children live in a "highly cultural development" environment, and the toys, pictures, TV, computers, etc. they are all close media. These media impact on the vision of young people. They are deprived of the opportunity to see far while acquiring knowledge. The accommodation ability of the ciliary muscle of the eye drops, and the ability of the ciliary muscle of the eye to see far will be blunt or even lost, which will cause myopia in teenagers. If children grow up in this environment for a long time, their vision will develop from pseudomyopia to true myopia.
Can myopia be treated?
In the treatment of myopia for teenagers, Qi Ying, an ophthalmologist in Tongren Hospital, stressed that children and children under 18 years old are not suitable for surgery, and it is better to wear glasses, which can improve their eyesight, but can not completely cure myopia.
But director Liu Yuqi thinks that it is effective to treat myopia with the combination of Chinese and Western medicine. This treatment solves the problem of ciliary muscle weakness, solves the problem of retinal nutrition, and gives children a chance to train in the distance. From these three aspects to solve the treatment of myopia at the initial stage, to enhance the ability of ciliary muscle and blood circulation of retina, to promote the development of children's visual system, combined with distance training to improve vision, can avoid mild myopia and pseudomyopia.
For teenagers with high myopia, director Liu said: high myopia should also be equipped with glasses: when looking near, we should use glasses with low degree to correct; when looking far, we should use full and accurate far degree to look far. The development of some degree of high myopia can be controlled by far and near, progressive myopia lenses and accurate optometry by optometrists.
According to Director Liu, there is a kind of "multi focus lens" in use, which can control the development of high myopia. "If the leg is not good, give him a crutch. Once you get rid of the crutch, the leg is still not good.". Myopia is also the truth, children can not rely on "glasses crutches" to live.
Director Liu also stressed that from the perspective of diopter, pseudomyopia and true myopia have their same definitions. In fact, parents should pay more attention to how to prevent, treat and control myopia in their living environment. Her advice to parents and teenagers is: don't relax your vigilance because of pseudomyopia, and don't walk into the misunderstanding of wearing glasses because of true myopia; don't use "vibrational massager" to treat myopia easily for high myopia, which may cause eye and retina injury.
In an interview with reporters, both experts stressed that myopia should be prevented. We should start from the children, even the fetus, especially in the children's learning stage, schools and parents should pay special attention to children's eye hygiene.
