There are too many misunderstandings in the prevention and treatment of myopia

Abstract: a recent survey shows that the incidence rate of myopia among primary school students in China is 22.78%, 55.22% for middle school students, and 76.74% for college students. The main causes of myopia are students’ heavy schoolwork burden, long time of close eye use, long time of watching TV and playing computer. Bruce Lee, a neighbor of

, is 13 years old and has put on more than 800 degrees of myopia glasses. Bruce Lee is the only child of three generations of single biography. The family regards him as the apple of their eyes and takes good care of him. Myopia appeared at the age of 9. As long as some therapeutic instruments and methods on the market have been tried all over, there are all kinds of eye protection lamps at home, and there are all kinds of instruments to treat myopia. However, Bruce Lee’s myopia degree is not only uncontrollable, but increases year by year. Last year alone, he changed three pairs of glasses, an increase of more than 300 degrees, which broke the brain of the whole family. A recent survey of

and

showed that the incidence rate of myopia among primary school students in China was 22.78%, 55.22% for middle school students, and 76.74% for college students. The main causes of myopia are students’ heavy schoolwork burden, long time of close eye use, long time of watching TV and playing computer. However, people’s vague concept of the mechanism of myopia and some treatment after myopia is also the factor causing the rising number and degree of myopia. The occurrence of juvenile myopia in

and

is not only partly due to the inheritance of high myopia by parents, but also caused by improper eye use, especially related to close-up work, such as insufficient lighting, too close reading distance, too long reading time, unclear or too small font and poor posture. Due to the heavy burden of study at ordinary times, the eyes of primary and middle school students can not get normal rest. During the holidays, some students often leave their books and pick up the TV; Out of the library, into the Internet cafe; Put down the counseling materials and pick up the game software. Although the mentality and body have been relaxed, the eyes are often more tired than at school.

and

use the eyes closely for a long time, causing excessive contraction of the ciliary muscle of the eyes, resulting in spasm of lens regulation, It can induce or aggravate axial myopia (myopia caused by too long anterior posterior diameter of eyeball, also known as true myopia); the regulatory spasm caused by excessive contraction of ciliary muscle will focus parallel light in front of the retina, but after dropping ciliary muscle paralysis agent, the spasm of ciliary muscle is relieved, which can improve this kind of myopia, that is, the visual acuity is improved or normal after medication, which is called regulatory myopia myopia (also known as pseudomyopia). In fact, due to the secretion of growth hormone and the instability and imperfection of endocrine system, teenagers in the period of growth and development tend to expand their eyeballs more easily than mature adults under the action of adverse factors. That is, we often see that the age of the occurrence and progress of most myopia is 12 ~ 18 years old, and after 18 years old, The development of myopia slows down or stagnates. Therefore, the occurrence and development of juvenile non hereditary myopia should be a process from quantitative change to qualitative change, that is, the development process from regulatory myopia to axial myopia. Knowing this truth, it is easier for us to identify the good and bad in the current myopia treatment market, and it is easier to choose the correct treatment methods and health care means. Generally speaking, that is, we should take reasonable methods to alleviate regulatory myopia as much as possible and minimize the transition from regulatory myopia to axial myopia. High myopia is not only the problem that the thick lens affects the beauty. The greater harm is that the retina will shrink if the myopia exceeds 600 degrees. The probability of retinal detachment in high myopia is much higher than that in emmetropia. A survey of

and

showed that 100 cases of emmetropia were tested after using the computer for 2 hours. The average visual acuity decreased by 0.2 and the average diopter decreased by -0.25d. It can be seen that it is harmful to use eyes for a long time. Therefore, it is an effective measure to prevent and slow down the occurrence and development of myopia to maintain good eye habits, not use eyes excessively and for a long time, pay attention to the interval between eyes, and pay attention to light and distance.

and

in case of vision loss, it is also the most undesirable to go to the eye shop on the street and wear a pair of glasses. As everyone knows, once many regulatory myopia are equipped with glasses, it will become axial myopia and lose the opportunity of treatment. If there is axial myopia before, under the action of regulatory factors, increasing the degree of glasses without treatment or mydriasis will accelerate the development of myopia. In fact, matching glasses is not only a problem of optometry, but also a strong medical truth. Therefore, the medical knowledge of glasses practitioners is very high, and the concept of “medical optometry” should be accepted by more and more people.

in order to avoid the degree mismatch of juvenile pseudomyopia, the method is actually very simple, that is to go to the hospital to accept the doctor’s correct mydriasis optometry procedure. The younger the age, the stronger the ability of ciliary muscle regulation, so mydriasis should be more sufficient. Atropine or tropicamide used in mydriasis is an effective ciliary muscle paralysis agent. After medication, it can identify true or false myopia and reduce the opportunity and degree of mismatch. Secondly, it can also treat false myopia. Kill two birds with one stone. Why not?

and

so far, there is no method that can become the ultimate scheme for the treatment of myopia. Therefore, only by combining effective medical means with vision health education can we completely solve the problem of prevention and treatment of myopia. There should be such a concept about the treatment of axial myopia. For patients with myopia under the age of 18, the safest and effective way is to wear frame glasses. Laser surgery is only suitable for adults over the age of 18. How can

and

be matched with a pair of appropriate glasses? We should master the following three principles: 1. When finding blurred vision, first ask an ophthalmologist to check and diagnose, and rule out other eye diseases to avoid delaying the condition; 2。 Ametropia patients should adhere to Optometry (mydriasis optometry is the best for those without contraindications) to determine the accurate diopter; 3. Before prescribing glasses, they must be retested (i.e. try to wear glasses), which combines objective optometry with subjective acceptance, so as to select the best diopter acceptable to patients. “Computer optometry, it is advisable at once” It is difficult to achieve accurate matching methods, especially for adolescent ametropia.
