Abstract: myopia is a very common ophthalmic disease. The most people with myopia are office workers, students, the elderly and so on. Found his myopia, how to prevent myopia degree deepening? Let’s follow Xiaobian to have a look., Myopia is caused by bad eye habits or other factors. It is a common phenomenon. However, some children are short-sighted, and their eyesight is constantly increasing. Every time they change their glasses, parents will feel worried. What should we do to slow down the growth of myopia?, Experts say that there are many reasons for the increasing degree. If you find it out and find it right, you will have a way., First, not wearing glasses will increase the degree. Why? Wearing glasses can improve eyesight, which can reach 0. 6. Be able to focus at a distance and relax the ciliary muscle. When looking close, the ciliary muscles work hard, like a rubber band stretched. If you can let it relax, it can keep the same length for a long time. If vision is less than 0. 6. Without glasses, the imaging is blurred when looking at the distance, and the ciliary muscle cannot be relaxed. This close-up state will be maintained all the time. Imagine pulling a rubber band open and not relaxing. If you put it again after 3 months, you will find that it is longer than the original and can’t go back. This rubber band can be used to compare the change from false myopia to true myopia. Myopia increased by only 0 in 3 months. 25d, but in the long run, it will be 1 every year. 00D。 Only by wearing glasses can we have the opportunity to block this development path. If it can be found in time, when the child just has blurred vision, a ciliary muscle paralysis optometry and a complete relaxation of the ciliary muscle may eliminate pseudomyopia in the bud. This medication can not only get accurate information about refractive status, but also has therapeutic effect. Cycloplegia occurs every three months, and some children can even delay wearing glasses for more than a year. Remember, vision is less than 0. 6. Be sure to wear glasses and always wear them on your face. Glasses that are only used in class and don’t wear when going out not only have no chance to relax, but also may pay more attention to fatigue., The second important factor is esotropia., In the case of recessive esotropia, when the close eye is used for a long time, the eyes will stagger inward, resulting in blurred vision. In order to be able to see clearly, try to make your eyes see together. As a result, the harder you work, the more severe the inclination. At this time, it will show a series of visual fatigue symptoms, and even transient high intraocular pressure. You may have myopia overnight 0. 30——0。 50D。 We compare recessive esotropia to a pile of dry firewood under the eaves. Reading and writing close to our eyes. Over time, visual fatigue appears, just like striking a match and throwing it into the firewood. This rapidly increasing myopia is like a house on fire and burning itself. How can we prevent this danger? We can neither remove this pile of dry firewood nor stop the children from reading and writing close to their eyes (striking matches), but we can set a high threshold to prevent matches from being thrown easily. For children before the age of 9, if there is implicit skew, the time of reading and writing every day shall not exceed 1. 5 hours; Children over the age of 10 can’t use their eyes more than 3 hours a day, which is obviously not enough for children to learn. We use an additional mirror with a spherical mirror and a prism. When reading, we put it on the glasses we usually wear to see close, and use the upper half of the original glasses to see far. This not only ensures that the adjustment can be reduced and the time of visual fatigue can be prolonged at any time, but also does not increase irregular astigmatism and reduce the best corrected visual acuity due to the long-term wearing of two degree lenses (students often wear gradient multifocal lenses for a long time). This kind of glasses is only used for patients with implicit inclination or implicit inclination, and will certainly not lead to implicit inclination., Some recessive exotropia may also lead to the increasing degree of myopia. Since both eyes cannot be used at the same time when looking at the distance, the fatigue time of using only one eye will be less than half of that of using both eyes at the same time; Look at the adjustment accumulated near, and there is no chance to relax when you look far. These two factors contribute to the increase of myopia. It is an effective way to solve this shortsightedness by adjusting the set training after wearing glasses. What is conditioning training? It’s very simple. It’s just looking from far to near. The specific method is to point to the distant target with your finger. It is best to be able to identify the target within 9 seconds. After you see it clearly, move your finger gradually to 30cm in front of you for 3 seconds, 15 minutes a day. Since children don’t have enough time to see far, we advocate extending the training time to 40 minutes and finishing it in several times. This is a major project initiated by the president of an ophthalmology society in the former Soviet Union. He asked 50000 people to participate in training and 50000 people to control for five years. The incidence rate of myopia among the two groups was not significantly different, but the difference between the two groups was very large (about 23 times). In other words, a large number of children who do this training have avoided high myopia. So far, this is also the only training method with medical basis in myopia prevention and control. Other instruments designed to simulate this training have not obtained effective evidence. Because of the devices on the desktop, natural conditions cannot be simulated.,

and
experts say that there are many reasons for the increasing degree. If you find it out and find it right, you will have a way.
first of all, without glasses will increase the degree. Why? Wearing glasses can improve eyesight, which can reach 0. 6. Be able to focus at a distance and relax the ciliary muscle.

If it can be found in time, when the child just has blurred vision, a cycloplegic optometry can be done completelyRelaxing the ciliary muscle once may eliminate pseudomyopia in the bud. This medication can not only get accurate information about refractive status, but also has therapeutic effect. Cycloplegia occurs every three months, and some children can even delay wearing glasses for more than a year. Remember, vision is less than 0. 6.

the second important factor is esotropia. In the case of

recessive esotropia, the eyes will stagger inward and the visual object will be blurred when the near eye time is too long. In order to be able to see clearly, try to make your eyes see together. As a result, the harder you work, the more severe the inclination. At this time, it will show a series of visual fatigue symptoms, and even transient high intraocular pressure. You may have myopia overnight 0. 30——0。 50D。 We compare recessive esotropia to a pile of dry firewood under the eaves. Reading and writing close to our eyes.

and
is large astigmatism. Generally more than 1. Astigmatism of 50dc is called large astigmatism. When wearing glasses with large astigmatism, it is difficult to completely match the corrected state with the eye state. Because the lens is regular, the greater the astigmatism of the human eye, the more difficult it is to be regular. According to statistics, every increase of 1. For astigmatism of 50dc, there may be 20% points, and the eyeball does not match the wearing glasses.
