Myopia refers to a pathological state that is clearly seen in the distance and is unclear in the distance. It is a kind of refractive error, and the visual object can not converge on the retina   through the refraction of the refractive system of the eyeball, so it cannot form a clear image on the retina. It is generally believed that the main cause of non-hereditary myopia is the excessive adjustment burden caused by excessive reading and other close-range activities. When the eyes are used for a long time, the ciliary muscles will paralyze and temporarily  lose the ability to relax, which would cause unclear vision, thus forming pseudo myopia. As a result, the ciliary muscle of the ankle may stimulate the stretching of the anterior and posterior axes of the eyeball, thereby causes irreversible true myopia. When we narrows eyes, the eyes can limit the incidence of light, thus reducing  aberrations and making us see clearer. Actually, long-term squinti...

Many people worry that wearing myopia will increase the degree of myopia, but experts say that the increase in the degree of myopia is not related to wearing glasses, but related to genetic and personal eye habits.👀👀 The benefits of wearing glasses In fact, wearing glasses will not only make myopia deeper, but effectively prevent or slow down the development of myopia. Because wearing glasses can eliminate eye fatigue, in the absence of glasses, myopia should look at distant objects, you must pick up your eyes, which will make the muscles inside and outside the fatigue, accelerate the development of myopia. In addition, wearing glasses also helps prevent strabismus from occurring. The person with myopia is less adjusted due to the nearsight, and the function of the two eyes is correspondingly weakened, which tends to make the eyes deflect outward and squint occurs. Why do some people wear glasses and myopia is really deepening? The reasons are mainly the followin...

In addition to poor eyesight, perhaps you still don't know that malnutrition is one of the causes of myopia in children. In addition, the technology is developed now, and parents and mothers should be reminded that children can easily enter the wrong zone with their eyes. Hence, it’s necessary to take more care in daily life. Child malnutrition is easy to induce myopia   Experts pointed out that in fact, the emergence of myopia in children is also related to malnutrition. Childhood is a critical stage in eye development, and calcium and chromium are indispensable, otherwise myopia will occur. Calcium is related to the formation of the eyeball. Insufficient intake can cause the sclera to be single-sexually reduced, the intra-crystal pressure rises, and the anterior-posterior diameter of the eyeball is elongated to cause myopia. Chromium is a cofactor for an important hormone insulin in the body. If it is lacking, insulin activity decreases, and the ability...
