Fourth, the sitting posture should be correct: don't stoop. The closer you get to doing homework or squatting, it will easily cause excessive tension in the ciliary muscles, leading to myopia.
5. The reading distance should be moderate: the distance between books and eyes should be 30 cm, and the height of tables and chairs should also match the physique.
6. Don't watch TV too close: When watching TV, keep the diagonal distance of the TV screen six to eight times, and have a rest every 30 minutes.
Seven, sleep can not be too little, regular work and rest: lack of sleep is easy to fatigue, easy to cause false myopia.
Eight, do more outdoor sports: often overlooking can relax eye muscles, prevent myopia, and get in touch with the green mountains and green waters in nature, which is conducive to eye health.

How to protect your eyes when swimming in summer?
In hot summer, swimming is a sport that people want to go to. It can not only strengthen their physique, but also make people enjoy the fun of summer. However, you should also pay attention to protecting your eyes before and after swimming.
After swimming, the eyes often appear red, swollen and astringent, and sometimes there are more secretions, which is the expression of conjunctival inflammation. Conjunctivitis after swimming is mostly caused by bacterial and viral infections. Swimming also spreads trachoma easily.
The water in swimming pools is usually disinfected by bleaching powder, which is a disinfectant with mild irritation and will cause non-infectious conjunctivitis because of this chemical stimulation. However, the concentration of bleaching powder in water is relatively low, which generally has no harm to eyes. On the contrary, bleaching powder disinfectant can inhibit the bacteria in the water and make the water clean, which can reduce the occurrence of infectious eye diseases. However, if the disinfection is not standardized or the swimmer's pre-swim inspection is not strict, it will also cause conjunctivitis after swimming. If you swim in the natural water of rivers, it is impossible to disinfect the water quality, especially the small rivers near towns. Residents do not pay attention to water hygiene when using water, and there are many opportunities for water pollution. After swimming in this water, it is easy to cause bacterial and viral conjunctivitis.
What should I do if my eyes are red after swimming?
Conjunctivitis caused by mild stimulation of bleaching powder disinfectant when swimming in the swimming pool is often caused by slight redness of eyes after coming out of the water, which will disappear on its own after a few minutes to a few hours, generally without treatment. If there is an aggravating trend or swimming in unsterilized water, it is easy to cause bacterial and viral conjunctivitis. Often the symptoms are mild or not obvious when coming out of the water. 1~2 days later, the eyes became red and the secretion gradually increased. Should be treated in time, with antibiotics or antiviral eye drops.
How to protect your eyes after swimming?
(1) It is forbidden for patients with "pink eye" or other infectious diseases to swim in public swimming places. Strengthen the physical examination before swimming.
(2) Try to choose swimming places with good water quality and less pollution.
(3) People with high myopia should not dive head-down to avoid retinal detachment.
(4) The swimming pool must be replaced and disinfected in time according to regulations.
(5) Conditional people, it is best to wash their faces and take a bath with clear water in time after swimming.
(6) When diving, try to close your eyes. You can wear protective glasses if you can.
For people who often have conjunctivitis after swimming, it is necessary to order antibiotic eye drops several times in time after each swimming, which has a certain preventive effect.
What do you know about protecting your eyes with your eyes?
Give me a pair of eyes.
Eyes are very important and fragile organs in our bodies. A stone and a wire can cause blindness. In addition, there are many diseases that harm the eyes, especially the eye health problems of teenagers and the elderly. For example, ametropia of school-age people, eye trauma of young and middle-aged people, cataract of the elderly and so on.
The high incidence of eyes is mainly reflected in young children, especially 14 years old. The incidence of myopia, amblyopia and strabismus is quite high. Besides some congenital reasons, we should also pay attention to acquired factors. Like improper use of eyes, the influence of TV and computer; Some parents teach their children to read books such as Children when they are very young, but there are no measures to prevent eye diseases. They don't understand that improper use of eyes in the development process is most likely to cause myopia, strabismus and other eye diseases.
In terms of eye protection, we must first establish a scientific awareness of protection. If you are sick, you should treat it by scientific means. For example, wearing OK glasses should be guided by a strictly trained professional doctor. If the eyes have refractive problems, it is appropriate to go to the hospital for treatment. Especially in the developmental period, teenagers should pay more attention to wearing myopia glasses. You need to check with an ophthalmologist first, and use drugs to dilate the pupil of the patient before optometry. 1 Check again after 3 weeks to determine how many pairs of glasses to wear. Moreover, the optician will go back to the hospital after 3 months or half a year to check whether the original glasses are suitable.
Noise and light pollution are harmful.
People all know the harm of water pollution, air pollution and noise pollution to human health, but they don't realize the potential threat around them-noise pollution is seriously damaging people's eyes. The consequences of noise and light pollution lead to the rapid increase of various eye diseases, especially myopia. According to scientific measurement, the light reflection coefficient of general white wall is 69-80%, the light reflection coefficient of mirror glass is 82-88%, and the light reflection coefficient of particularly smooth white wall white book paper is as high as 90%, which greatly exceeds the physiological adaptation range that human body can bear and constitutes a new modern pollution source. Studies have shown that noise and light pollution can damage the cornea and iris of human eyes, inhibit the function of retinal photoreceptor cells, and cause visual fatigue and vision decline.
According to experts, noise pollution in the visual environment can be roughly divided into three types: one is outdoor visual environment pollution, such as building exterior walls; Second, indoor visual environment pollution, such as indoor decoration, indoor bad light and color environment. Third, local environmental pollution, such as books and newspapers and some industrial products. The visual environment has seriously threatened people's healthy life and work efficiency, causing a lot of losses to people every year. Some experts predict that the research of visual environmental protection technology and the development of eye protection products will be the hot spots in 2 1 century, and the emerging industries gradually formed by visual environmental protection technology will produce huge economic and social benefits.
Eye-friendly food
To protect your eyes, in addition to paying attention to the combination of work and rest, don't read books, watch TV and do eye exercises for a long time. Eating some food that is good for your eyes can also play a great role in protecting your eyes. So, what foods are good for the eyes? The first is lean meat, poultry, animal offal, fish and shrimp, milk, eggs, beans and so on. , which is rich in protein, and protein is the main component of cells, so tissue repair and renewal need to constantly supplement protein. Secondly, foods containing vitamin A are also good for the eyes. When vitamin A is deficient, the adaptability of eyes to dark environment decreases, and it is easy to suffer from night blindness in severe cases. Taking enough vitamin A every day can also prevent and treat dry eye. The best source of vitamin A is the liver of various animals, while plant foods, such as carrots, amaranth, spinach, leeks, green peppers, sweet potatoes with red hearts and oranges, apricots and persimmons in fruits, etc. Finally, eat more foods containing vitamin C, because vitamin C is one of the components that make up the eyeball lens. If vitamin C is lacking, cataract with turbid lens will easily occur. Foods rich in vitamin C include all kinds of fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, Chinese cabbage, fresh dates, pears and oranges.
Office gens eye protection
With the development of information technology, operating computer terminals is almost an inevitable part of modern life. Many people, such as programmers, counter attendants, bank employees, information center staff, word processors, etc. I have to face the computer and stare at the computer screen all day. After working for a long time, their eyes get tired easily.
In the eye clinic, patients often complain about eye fatigue or headache, among which computer terminal operators account for the majority. The best way to avoid eye fatigue is to rest in the middle, not to operate continuously. At the same time, the posture and distance of work are also very important. Try to keep the distance above 60 cm and adjust the most suitable posture, so as to protect the line of sight down about 30 degrees. Finally, whether the brightness and clarity of the screen are appropriate, whether the ambient light is soft, and whether the height and comfort of the desk and chair can match the height of the terminal are all factors that must be considered. If the symptoms of eye fatigue are very serious and cannot be improved, you must consult an ophthalmologist and use artificial tears or ciliary muscle relaxants to improve the symptoms of eye fatigue.
Eyes are very important to everyone's life, so we should always pay attention to our own health and establish the awareness of eye disease prevention and treatment. If you are an optician, it is very important to match a pair of suitable glasses. If you are not an optician, you might as well know more about eye diseases. Especially in schools and families, children should establish good eye care habits. Because the myopia rate of children in China ranks second in the world, it is urgent to save the eyes!
