Three common sense of preventing myopia in teenagers who can be blinded by severe myopia

Abstract: myopia is the symptoms of eye diseases that can’t see distant objects clearly, but can see nearby objects. It is just the opposite of presbyopia. However, myopia is not just a matter of looking at things. A series of eye diseases caused by myopia further endanger human health and people’s normal life., According to the joint investigation by the Ministry of health and the Ministry of education, the incidence rate of myopia among China’s students is nearly 60%, ranking the highest in the world. At present, among Chinese students, the myopia rate of primary and middle school students has reached 34.6%, that of high school students has reached 70%, the number of patients has exceeded 60 million, and the number of blind people caused by myopia has reached 300000. The sharp decline of eyesight has a direct impact on children’s academic performance, further education and employment, and has a varying degree of impact on their physiology and psychology. Now the popularity of TV, computer and mobile phone has brought convenience to people, but it has greatly affected children’s eyes. Parents who often pick up their children will find that there are more and more myopia children, and they are getting younger and younger., The degree of myopia deepens, and severe cases can cause blindness. Myopia is the symptoms of eye diseases that can’t see distant objects clearly, but can see nearby objects. It is just the opposite of presbyopia. However, myopia is not just affecting seeing. It causes a series of eye diseases, which further endanger human health and people’s normal life. Parents must let their children know the harm of myopia. Myopia will reduce eyesight, often dry and tired eyes, affecting the quality of study, life and work., Wearing glasses for a long time will cause inconvenience to life and work. Medium and high myopia will also lead to eyeball protrusion, and the chance of retinal detachment is seven or eight times higher than that of patients with non high myopia, resulting in many serious complications. For example, the incidence of posterior scleral staphyloma is 77.1%, the incidence of subretinal neovascularization is 5% – 40%, about 30% of high myopia suffer from glaucoma, and the chance of high myopia complicated with cataract is also higher than that of normal people. It is particularly easy to cause vitreous opacity, retinal hemorrhage and detachment, resulting in a more serious consequence – blindness. This is one of the common causes of blindness in adults. It can cause eyelid relaxation and affect appearance. It will be limited in entering school, joining the army, taking an examination of civil servants and looking for a job., There are three common knowledge for teenagers to prevent myopia. 1. Eat more coarse grains and less sugar. The lack of trace element chromium in the body has a certain relationship with the formation of myopia. Chromium mainly exists in coarse grains, vegetables, fruits and other foods. Some parents do not pay attention to food matching and eat some fine food for their children for a long time, resulting in chromium deficiency in the body, convex lens and increased diopter, Produce myopia. In addition, teenagers like sweets. Excessive sugar can make human blood sour. In order to maintain acid-base balance, the human body has to mobilize a lot of calcium to neutralize acid roots, resulting in insufficient blood calcium, weakening the elasticity of eye wall, lengthening eye axis and sowing the hidden danger of myopia., According to the joint investigation by the Ministry of health and the Ministry of education, the incidence rate of myopia among China’s students is nearly 60%, ranking the highest in the world.

At present, among Chinese students, the myopia rate of primary and middle school students has reached 34.6%, that of high school students has reached 70%, the number of patients has exceeded 60 million, and the number of blind people caused by myopia has reached 300000. The sharp decline of eyesight has a direct impact on children’s academic performance, further education and employment, and has a varying degree of impact on their physiology and psychology. Now the popularity of TV, computer and mobile phone has brought convenience to people, but it has greatly affected children’s eyes. Parents who often pick up their children will find that there are more and more myopia children, and they are getting younger and younger.

myopia can cause blindness if the degree of myopia is deepened.

myopia is that you can’t see distant objects clearly, but you can see the eye disease symptoms of nearby objects. It is just the opposite to presbyopia. However, myopia is not just affecting seeing. It causes a series of eye diseases, which further endanger human health and people’s normal life. Parents must let their children know the harm of myopia. Myopia will reduce eyesight, often dry and tired eyes, affecting the quality of study, life and work.

has a certain relationship with the formation of myopia. Chromium mainly exists in coarse grains, vegetables, fruits and other foods. Some parents do not pay attention to food matching and give their children some fine foods for a long time, Thus, the body lacks chromium, the lens becomes convex, the diopter increases, and myopia occurs. In addition, teenagers like sweets. Excessive sugar can make human blood sour. In order to maintain acid-base balance, the human body has to mobilize a large amount of calcium to neutralize acid roots, resulting in insufficient blood calcium, weakening the elasticity of eye wall, lengthening eye axis and sowing the hidden danger of myopia.

2. Do more chewing eye exercises

too little hard food is also one of the reasons for the increase of juvenile myopia. When eating food, promote facial muscle movement, including the muscles that control eye movement, so as to effectively play the ability to regulate eye lens. Researchers have investigated nearly 300 students. Those who like hard food are normal, and those who often eat soft food decline in varying degrees. Therefore, chewing is known as eye exercises. Therefore, according to children’s tooth development, arranging chewable hard foods such as carrots, potatoes, soybeans and fruits to increase chewing opportunities can prevent myopia.

3. Limit close eye use

to prevent myopia, strictly limit the time for close eye use. After learning for 40 minutes, you must rest for 10-20 minutes to make your eyes rest regularly. At the same time, increase the reading distance, and the longer the reading distance
