The eyes are the windows to the soul. We must protect our eyes. Let's talk about how to prevent myopia!
First, scientific use of the eyes For myopia, we can only prevent it, because when a person is nearsighted, the traditional methods are difficult to reverse. Without myopia, myopia can be prevented. With myopia, the degree of control will deepen.
You must pay attention to your posture when studying or working. When sitting, the distance between the table and the book is preferably more than 30 cm (about one foot) from the eyes; When writing with a pen, the distance between the nib and the finger is about one inch; When writing on the table, the distance from the table should be about one punch.
When we study with our eyes, never read or write in a very dark environment, which will do great harm to our eyes. Don't read books and watch mobile phones in the bumpy car, it will damage your eyes. When we are reading, I don't want to lie in bed or lie prone on the bed for comfort, which will do some harm to my eyes.
Second, outdoor sports Outdoor sports must choose daytime. If you want to exercise, walk, run and jump outdoors after self-study at night, it will not play much role in preventing myopia. Because there is enough light and spectrum during the day.
When we talk about outdoor activities, there is not much demand. If you choose to run, walk or ride a bike, these are all ok, even if you are alone in a daze. Outdoor activities are not important in themselves. It is important to put tired eyes outdoors to get in touch with the light. During running, the eyes will look straight ahead, and the chance of myopia will be reduced. Although outdoor exercise has little effect on the eyes, it is good for other parts of the body. Choose outdoor exercise after sitting for a long time, which not only relaxes the body but also protects the eyesight.
One thing must be paid attention to, don't let the sun shine directly, preferably when the sun is not shining directly. ?
Third, don't stay up late in the dark to study with your eyes. Coupled with the strong light stimulation of mobile phones and computers, it is easy to cause problems such as dry eyes and decreased vision.
Fourth, provide comprehensive nutrition because the health of the eyes comes from the health of the whole body, so all kinds of nutrition should be supplemented. Children and teenagers should never form the bad habit of picky eaters. As long as they are not picky about food and eat all kinds of food every day, they will not lack nutrition.
Vitamin a is good for eyesight. Vitamin A, also known as retinol, mostly exists in the viscera of mammals and marine fish, and there is almost no vitamin A in plant foods. Plant food contains carotenoids, which can be converted into vitamin A in human body, so vitamin A can be directly supplemented or carotenoids can be supplemented.
1. Animal food: Animal food (such as liver, kidney, eggs and milk) is rich in vitamin A, especially liver;
2. Both green vegetables and red and yellow vegetables and fruits contain carotenoids, such as broccoli, carrots, pea seedlings, red sweet potatoes, spinach, amaranth, rape, oranges, loquat and so on.
