The incidence of myopia ranks second in the world. It is said that the eyes are the windows of the soul, but the eyes are very fragile. The main source of information we receive is our eyes. Good eyesight is very important to us.
Only with a pair of beautiful eyes can we protect our future. But now many people ignore the help of eyes. The number of nearsighted people in China is close to 400 million, especially teenagers, which has reached 270 million.
There are many reasons for vision loss, and the preventive measures are different. Usually, people say that vision loss can be roughly divided into the following reasons:
1. Non-occupational vision decline caused by bad habits in daily study/life, which is the situation of most teenagers. In addition, people with low heads can be seen everywhere in life, playing mobile phones all night and facing electronic products all day, resulting in more and more people wearing glasses.
2. With the increase of age, the physiological function of eyes naturally declines.
Hereditary vision loss can usually be found in the family. If there are genetic factors leading to decreased vision, it is best to go to a specialized hospital for a comprehensive examination and follow the doctor's advice.
4. The vision loss caused by occupation is very complicated. The general requirement is to raise awareness and do self-protection.
There are all kinds of mysterious "treatment" and "protection" methods circulating on the Internet, but few of them are really effective and convenient for people to actually use. Therefore, protecting eyes should be a habit developed from childhood.
1. Usually, the easiest way to protect your eyesight is to do eye exercises. Eye exercises can eliminate eye fatigue, protect eyesight and prevent myopia. Stretching or walking to the window and looking at the green plants in the distance can effectively protect your eyesight.
2. The most effective way to reduce non-occupational eyesight caused by study and work in daily life is to pay attention to eye hygiene. Poor eyesight is related to poor light (too dark, too bright, glare, reflection, etc.). ) You can get good visual enjoyment by studying in comfortable light. Too strong or too dark light will bring bad effects to your eyes. Do a good job of anti-reflection treatment to reduce the damage to the eyes.
3. Most students' eyesight decline is due to the decline of eye mediation function. Long-term close use of eyes in poor ambient light is the main reason for myopia and myopia deepening. When using eyes at close range, the body should be at rest, and the eyes should keep a proper distance (not less than 30cm) from the book/computer. Get up every hour to exercise, see more distant places, see more scenery, turn your eyes, you will get a little relaxation, and it is also a massage for your eyes.
4, more outdoor sports/activities, while promoting blood circulation, eyes will have more hyperopia time, and can also help relax eye muscles/nerves, which is self-evident for vision protection.
5. Many people have such a bad habit that whenever their eyes feel sour, they will rub them with their hands, which is very dangerous! Our hands will be exposed to a large number of bacteria, and handling eye discomfort by hand will cause infection to the eyes and even form eye diseases.
6. Whether you are in class, reading or doing homework, don't hunch over, or read at your desk, let alone read in bed. Protect your eyesight and get enough sleep. Work and rest should be regular, because lack of sleep can easily lead to fatigue and pseudomyopia.
7. If it is pseudomyopia, it can be corrected according to the above method. If you are already nearsighted, you'd better choose glasses with relative degrees. The more you don't want to wear glasses when you are nearsighted, the deeper your myopia is. Another point is, don't think that you are nearsighted and don't need to protect your eyesight, which will aggravate myopia. Check your eyesight regularly and establish a refractive file (the result can be compared with the normal value to understand the development process and "early warning" in time).
8. Pay attention to balanced nutrition and don't be partial to food. You can eat some eyesight-improving foods in moderation, such as animal livers or fruits and vegetables containing vitamin A, oranges, grapes, lemons, bananas, bean sprouts, carrots and tomatoes, which can effectively protect your eyesight.
Carrots: The most helpful element for eyes is vitamin A. Without vitamin A, people will get night blindness. Vitamin A contains the most important substance to maintain eye health-antioxidant β-carotene, and carrots are the best choice to take vitamin A. ..
Lycium barbarum: Lycium barbarum has many functions, such as tonifying kidney, producing sperm, nourishing liver and improving eyesight. There is a substance on the retina, which can reduce the stimulation of ultraviolet rays and protect the visual nerve from damage after a large amount of accumulation. Zeaxanthin, which can't be produced by human body, can only be obtained from food, and the content of most foods is very low. Only Lycium barbarum is rich and can be directly absorbed by human body.
Spinach: Spinach contains a lot of lutein. The main function of lutein is to prevent eye aging, which is very helpful to prevent cataracts. At the same time, green leafy vegetables are also a good source of vitamin B2 and β-carotene. When vitamin B2 is sufficient, eyes are not easily congested. β -carotene can be converted into vitamin A in the body to prevent symptoms such as "dry eye".
There are different reasons for poor eyesight. If the vision has decreased (such as myopia), we should analyze the reasons as soon as possible and try to correct it, otherwise it will delay the opportunity to restore vision.
