Teenagers have a high incidence of myopia. Physical exercise is an effective prevention method

Abstract: exercise can first improve the overall physical quality and promote blood circulation. The eyes of children and adolescents are not fully developed. Exercise can promote the absorption of nutrients and restore visual fatigue as soon as possible. The

range of 6-18 years old is called myopia susceptibility period in medicine. If you don’t pay attention to protecting your eyes during this period, you are very likely to suffer from myopia. Myopia may not only cause other eye diseases, but also affect children’s mental health, reduce children’s interest in external things, gradually narrow the scope of life, and even affect children’s intellectual development in serious cases.

and

physical exercise are considered to be the most effective prevention methods. Physical exercise can promote vision, promote eye development on the basis of improving various physical qualities, and at the same time, it is an active way of rest, which can play a role in the prevention and treatment of myopia.

first of all, let’s talk about why physical exercise can prevent myopia.

1. It can increase eye nutrients and provide

. Exercise can first improve overall physical fitness and promote blood circulation. The eyes of children and adolescents are not fully developed. Exercise can promote the absorption of nutrients and restore visual fatigue as soon as possible.

2. Adjust the ciliary muscle

. The earlier you exercise the ciliary muscle, the greater the benefits to children’s eyes. The root of children’s myopia lies in the tension of the ciliary muscle. Therefore, the earlier you help children exercise their ciliary muscles, the greater the possibility of vision recovery.

myopia is because the anterior posterior diameter of the eyeball is too long and the retina is too far away from the lens, so that the directional light from a distance can not converge on the retina.

the structure of the lens in human eyes is similar to a convex lens. True myopia is due to the deformation of the lens caused by ciliary muscle fatigue for a long time, which makes the anterior and posterior meridians of the eyeball exceed the normal length; Pseudomyopia is caused by excessive tension of ciliary muscle pulling the lens, fatigue, spasm and lens refraction. Whether true or false myopia, in diet, eat more animal liver, eggs, carrots, etc. You can also drink Kunlun snow chrysanthemum to clear the liver and eyesight, clear away heat and detoxification, protect eyes and eyesight.

how should my teenagers choose physical exercise to prevent myopia

sports such as football, basketball, baseball and football, especially football, belong to aerobic and anaerobic mixed sports. Because of its wide range of sports, wide vision and complete relaxation of ciliary muscles, it can effectively alleviate eye fatigue, With the constant movement of the ball and players, teenagers’ eye muscles can also be effectively adjusted and fully relaxed.

and

sports, such as table tennis, badminton, volleyball and tennis, with the ball moving back and forth, the eye muscles contract and relax alternately; Outdoor games such as throwing Frisbee, kicking shuttlecock, throwing sandbags, flying kites, etc. train the coordination ability of hands, feet, eyes and brain, constantly move the eyes and stare at the distance, so as to exercise the eyes and prevent juvenile myopia.
