Abstract: since its birth in the 1960s, eye exercises have accompanied the growth of children from generation to generation. Many people have the misconception that if they have myopia, eye exercises can play a therapeutic role, or that frequent eye exercises can prevent myopia, but in fact eye exercises do not have such a function., If you go to school, you will find that more and more young people have suffered from myopia in the past 20 years, which is obviously much more than those born in earlier times. According to statistics, the incidence rate of myopia in China is as high as 50%-60%. The number of glasses in the country has exceeded 300 million, ranking the first in the world. The limitation of myopia is becoming younger and younger. Why on earth is this?, The causes of myopia include congenital genetic factors and acquired developmental factors. The rapidly increasing prevalence of myopia is mainly caused by the changes of acquired factors. People’s eyes are not fully developed in adolescence. If they do not pay attention to eye hygiene in adolescence, over time, it will cause permanent changes in the shape of the eyeball, resulting in myopia, which is the main cause of myopia., As for the reasons for the increasing prevalence of myopia among Chinese teenagers, on the one hand, due to the increasing pressure of social competition in recent years, more and more children have participated in a large number of education classes and counseling classes since pre-school, and they have to face a heavy schoolwork burden after school; On the other hand, with the progress of science and technology, more and more children begin to contact computers, game consoles and other electronic products from an early age and stare at the screen for a long time. These two factors lead to the premature increase of children’s eye load, far exceeding those born in earlier years. Therefore, the risk of myopia has greatly increased compared with the past., Eye exercises are used to alleviate visual fatigue. Since its birth in the 1960s, eye exercises have accompanied the growth of children from generation to generation. Many people have such a misunderstanding that if they have myopia, eye exercises can play a therapeutic role, or that frequent eye exercises can prevent myopia, but in fact eye exercises do not have such a function. Most myopia is caused by the lengthening of the axis of the eye, that is, the shape of the eye, which should be close to a circle, becomes longer and oval. In addition to congenital genetic factors, it is mainly related to poor eye habits in childhood., The principle of eye exercises to improve vision from the point of view of modern medicine, it is mainly to stimulate the excitability of vision related nerves by massaging the acupoints around the eyes to improve vision temporarily. This is only a temporary effect and will not have any obvious impact on the physiological structure of the eye. It will not change the shape of the eyeball, so it will not have the effect of preventing and treating myopia., Most probably it did not actually happen that the eye exercises China eye exercises. Incidence rate is high. This inference does not point out the logical relationship between the two indicators, so it can not prove that they have causality. If we follow this logic, China is still the country that speaks the most Chinese, we can also get the absurd result that “speaking Chinese will lead to myopia”. Others believe that people who have not received training are not easy to find acupoints, resulting in adverse effects. In fact, this worry is unnecessary. In traditional Chinese medicine, acupoint massage follows the idea of “leaving the acupoints but not the meridians”. The acupoints of the human body are not a small point, but an area. Even if they deviate a little, it doesn’t matter as long as they don’t deviate from this meridian. Even if there are many deviations from acupoints, the therapeutic effect is not good at most. Although doing eye exercises itself will not cause damage to the eyes, if you do eye exercises with long nails or dirty hands, you may accidentally hurt your eyes or cause bacterial infection.,
go to school and you will find that more and more young people have suffered from myopia in the past 20 years, which is much more than those born in earlier times.

eye exercises are used to alleviate visual fatigue.
eye exercises have accompanied the growth of generations of children since their birth in the 1960s. Many people have such a misunderstanding that if they have myopia, eye exercises can play a therapeutic role, or that frequent eye exercises can prevent myopia, but in fact eye exercises do not have such a function. Most myopia is caused by the lengthening of the axis of the eye, that is, the shape of the eye, which should be close to a circle, becomes longer and oval. In addition to congenital genetic factors, its causes are mainly related to poor eye habits in childhood. The principle of
and
eye exercises to improve vision from the point of view of modern medicine, it mainly stimulates the excitability of vision related nerves by massaging the acupoints around the eyes, which is only a temporary effect and will not cause any obvious impact on the physiological structure of the eyeRing. It will not change the shape of the eyeball, so it naturally does not have the role of preventing and treating myopia. Most probably it did not actually happen that China’s eye exercises were
and
. Today, some famous people in society have also issued such a voice. They think that the incidence rate of myopia in China is high, and it is the only country that eye exercises nationwide. This inference does not point out the logical relationship between the two indicators, so it can not prove that they have causality. If we follow this logic, China is still the country that speaks the most Chinese, we can also get the absurd result that “speaking Chinese will lead to myopia”. Others believe that people who have not received training are not easy to find acupoints, resulting in adverse effects. In fact, this worry is unnecessary. In traditional Chinese medicine, acupoint massage follows the idea of “leaving the acupoints but not the meridians”. The acupoints of the human body are not a small point, but an area. Even if they deviate a little, it doesn’t matter as long as they don’t deviate from this meridian. Even if there are many deviations from acupoints, the therapeutic effect is not good at most. Although doing eye exercises itself will not cause damage to the eyes, if you do eye exercises with long nails or dirty hands, you may accidentally hurt your eyes or cause bacterial infection.
although eye exercises do not have the effect of effectively treating myopia, it is not without benefits. From the perspective of Western medicine, the health care function of eye exercises is mainly to alleviate the visual fatigue after using the eyes for too long by promoting the blood circulation of the eyes and relaxing the muscles around the eyes. Especially for those who work at their desk all year round and use computers for a long time, they often do eye exercises and have a rest for their eyes, which can greatly alleviate eye fatigue and discomfort caused by long-term use of eyes, such as headache, dizziness, dizziness and nausea. This is the real role of eye exercises.
and
can only be used to correct myopia by surgery / glasses. The prevention of
and
myopia mainly depends on developing good eye habits in adolescence. At present, in addition to glasses, myopia surgery is the only effective way to correct myopia.
with the current technology, excimer laser myopia surgery is the most effective method to treat myopia, but many people have great concerns about it, and some even regard it as a conspiracy for profit in the medical community. In fact, excimer laser myopia surgery has been a relatively mature and safe technology since its birth in 1990. Millions of people in China have successfully removed their glasses after surgery.
however, not everyone with myopia is suitable for excimer laser myopia surgery. The safety and postoperative effect of surgery are very different for different people. The principle of excimer laser myopia surgery is to use laser to thin people’s cornea to change refraction. The higher the degree of myopia, the more people need to wear off. Therefore, people with particularly high myopia are not suitable for this kind of operation, because too thin cornea will have an adverse impact on the cornea and make the eyes more fragile. In addition, because the accuracy of this operation has an error of about plus or minus 50 degrees, the effect of surgery for people with very small myopia will not be obvious. The degree range suitable for excimer laser myopia surgery is generally about 100 degrees to 1500 degrees. In addition, in addition to the degree, we also need to do some corneal examination and other eye examination for comprehensive judgment. Before the operation, the doctor will explain the risk situation and expected effect of the operation to the patient, and finally decide whether the operation depends on the patient himself. In addition, teenagers under the age of 18 should also be careful when performing myopia surgery, because at this time, the eyes are still not stereotyped in the process of development, and the postoperative visual acuity is easy to change, affecting the effect of surgery.
and
although excimer laser myopia surgery is relatively safe, it is not completely free of side effects. Its side effects are mainly that there may be discomfort such as dry eyes and foreign body sensation for a period of time after operation, which will take a period of time to gradually adapt. In addition, the glare will increase when watching the lights at night, especially when driving at night. Many ophthalmologists still wear glasses, so some people speculate that this kind of laser surgery is unsafe. In fact, this is only because the postoperative glare increases. When operating the operating microscope, the light inside will make people feel dazzling and uncomfortable.
it is worth mentioning that the principle of laser correction of myopia can be said to “grind” a pair of appropriate glasses on the cornea, so that the external light can accurately converge and image in the fundus, so as to achieve the purpose of correcting myopia. This is only “corrected vision”, not “radical cure” myopia. The eye is still the original myopia. The possible complications of myopia, such as glaucoma and retinal detachment, may still occur. Therefore, even if the operation effect is very ideal, don’t think that everything will be fine after the operation.
