Parents should know that outdoor sports can prevent myopia

Abstract: sun exposure can promote the human body to secrete more vitamin D. Vitamin D can increase the absorption of calcium. Calcium is an indispensable element of human body. Only for the eyes, calcium deficiency is easy to weaken the elasticity and surface tension of the eye wall, and it is easy to lengthen the eye axis and develop myopia when using the eyes at close range or in the state of lowering the head.

today’s children generally live in buildings. They are not as easy to go out as bungalows. If they can’t see the sun, they are naturally prone to myopia. Therefore, do not attribute the cause of children’s myopia only to reading, but also consider other factors.

the benefits of sun exposure to prevent myopia

1. Sun exposure can promote the human body to secrete more vitamin D. Vitamin D can increase the absorption of calcium. Calcium is an indispensable element of human body. Only for the eyes, calcium deficiency is easy to weaken the elasticity and surface tension of the eye wall, and it is easy to lengthen the eye axis and develop myopia when using the eyes at close range or in the state of lowering the head.

2. Sun exposure can promote the human body to secrete more dopamine. Dopamine can effectively inhibit the growth of eyeball, which can inhibit the occurrence and development of myopia.

3. Sunshine can shrink children’s pupils, increase the focus of their eyes and see things more clearly, so as to prevent the occurrence and development of myopia.

4. Because most of the sun exposure is outdoors, when the sun is too strong, people generally do not use their eyes too close, but look into the distance and move more to relax their eyes. This is precisely the best way to protect their eyesight, which is conducive to the prevention and treatment of myopia.

outdoor sports, activities and play are beneficial to the prevention of myopia

1. Outdoor sports, activities and play reduce children’s opportunities to use their eyes at close range and increase the time to see far, which is very conducive to the prevention and control of the occurrence and development of myopia.

2. Sports can strengthen the body and enhance the function of the five zang organs. Traditional Chinese medicine believes that the eyes are divided into five rounds, corresponding to the five zang organs. If the five internal organs are healthy, the eyes are clear and bright, and it is not easy to be short-sighted.

3. Sports can develop human muscles and strengthen the function of eye muscles. Eye muscles, especially ciliary muscles, have normal regulation function and strong relaxation, and the eyes are not prone to myopia.

4. When people look at objects, they can see clearly only when the image of the object is focused on the retina of the posterior wall of the eye. When looking close, the eye muscle can focus on the retina and see clearly by adjusting the extension of the eye axis; When looking far, the eye muscle can focus on the retina and see clearly by shortening the eye axis. The extension of ocular axis is a homeopathic process when looking close; The shortening of the eye axis by looking far is a counter trend process, which requires greater force. Where does this power come from? It comes from ordinary sports.

5. It is found that children with myopia, especially high myopia, have higher intraocular pressure than normal children. High intraocular pressure promotes the elongation of ocular axis and the occurrence and development of myopia. Sports can level people’s blood pressure and reduce intraocular pressure, so as to reduce the chance of occurrence and development of myopia. In addition, long-term bending and head lowering, head position reduction and weight-bearing can make eyeball congestion, elevated intraocular pressure and longer eye axis, and increase the probability of occurrence and development of myopia.
