Green is good for the eyes, look more lawn woods; eyes to keep a certain distance from books, computers, TV; computers, TV brightness should not be too high; do not lie down to read; usually use the eyes for an hour to do eye exercises look away for ten minutes; do not use dirty hands to rub the eyes; wipe the face of the towel do not mix to prevent infectious diseases; carrots contain vitamin B, good for the eyes; eat more animal liver can cure night blindness.
Myopia patients generally lack chromium and zinc, myopia patients should eat more food containing more zinc. Foods such as soybeans, almonds, nori, kelp, lamb, yellow fish, milk powder, tea, meat, beef and liver contain more zinc and chromium and can be increased in moderation. It is best to take protein zinc, such as new Rarely used tablets, for zinc supplementation.
1. The time spent in close eye contact should not be too long
Take a break for 10-15 minutes every 45-60 minutes. During the break, you should look out of the window or do outdoor activities to relax the eye muscles.
2.The light should be moderate when using eyes at close range
Too strong or too weak light when using eyes at close range is an important factor in causing myopia. Therefore, at night or in a dark environment, lighting is best used 40 to 60W incandescent lamp, placed in the upper left corner of the desk. This is because the incandescent light is relatively soft, good color rendering performance, the eye can easily adapt to prevent the light is too strong or too dark brought about by eye fatigue.
3, close eye posture should be correct
Close eye posture is another factor that affects the incidence of myopia. When using eyes at close range, the table and chair height ratio should be appropriate, sitting, books placed 30cm from the eye. Bad eye habits such as reading in a car, reading in bed or reading with a tilted head will increase the burden of eye regulation and convergence frequency, increasing the pressure of the extraocular muscles on the eye, especially in primary and secondary school students, the eye is in the developmental stage, the ball wall stretch is relatively large, long time bad eye posture is likely to cause abnormalities in the development of the eye, leading to the formation of myopia.
4, actively participate in physical exercise to enhance physical fitness
The quality of the body is also closely related to the occurrence of myopia in adolescents. For example, children who are malnourished, suffering from acute and chronic infectious diseases, weak, partial or greedy for sweets often have myopia.
Therefore, in daily life, the diet of adolescents should be a reasonable mix of meat and vegetables, not partial diet, to ensure that all nutrients are complete and balanced. During the day, it is necessary to strengthen physical exercise, such as running, doing radio exercises, playing ball, playing shuttlecock, etc.. In addition, eye exercises are also a good way to prevent myopia, self-care, you can do eye exercises in between reading and writing, to play a role in relieving eye fatigue.
1.Eye movement method
When the head rotates up, down, left and right, the eyes also move with it.
2.Blink method
Tilt your head back and keep blinking to keep the blood flowing. When the eyes are slightly tired, just do 2~3 blinking exercises.
3.Hot and cold compresses alternate method
A towel dipped in hot water a little hotter than bath water, another towel dipped in cold water with ice, first put the hot towel on the eyes for about five minutes, and then put the cold towel for five minutes.
4, eye gymnastics
Middle finger pointing between the eye sockets and the bridge of the nose, palm cover face back and forth friction for five minutes. Then the neck slowly move around, then close your eyes, make a fist and tap the back of the neck ten times.
5.Look far and look near method
Look away for three minutes, then look at the palm of your hand for 1 to 2 minutes, and then look away again. This exchange of near and far several times, can effectively eliminate eye fatigue. Try it!
6, the computer a family of eye care tips
Clinically, we often encounter such patients, their symptoms are “dry eyes, even dry, photophobia, blurred vision”. Most of these patients are computer operators, copy editors, art workers, teachers and embroidery workers. With the popularity of computers in work and life, this condition is more common. Their symptoms are not caused by pathological changes, but due to improper use of the eyes.
6.Many harmful effects of not looking away
Long time “concentration, eyes do not turn” on the eyes is extremely harmful. First of all, a high degree of nervous tension will make the eyes swollen, the optic nerve function chronic decompensation; furthermore, prolonged close eye use, will contribute to the development of axial myopia; in addition, is the blinking action to reduce the lack of lubrication and protection of the eye. According to statistics, the normal number of blinks per minute is about 15, and in times of concentration, only 2 to 3. This causes too many tears to evaporate from the surface of the eye and too late to get timely replenishment, which in time causes inflammation of the eye surface.
Such patients, early examination results often do not detect any disease, but in the long run, they may lose their healthy eyes. For adolescents, prolonged close use of computers can cause adjustment spasms that make it difficult to see far away and then cause true myopia. For people over 45 years old, because of the decline in eye regulation, presbyopia, near vision fatigue, and can not last, if long-term gaze at the computer will make fatigue symptoms aggravated, may also induce glaucoma, cataracts and other eye diseases.
7, work and rest to prevent eye disease
(1) to prevent or eliminate this situation, daily attention should be paid to the care of the eyes, the key is to be persistent, can be done from the following aspects.
(1) avoid long periods of continuous operation of the computer and reading and studying, do not wait until you feel eye fatigue to rest, but should be every hour or so to rest 10-15 minutes, rest or look out of the window to see the green trees or vision, or do eye exercises, so that the eyes fully relaxed.
(2) operate the computer and read books and study to maintain a good working posture. Maintain a most appropriate posture, so that the eyes are flat or light to look down at the fluorescent screen, so that the neck muscles can relax, and make the eye exposed to the air to minimize the area. Do not read lying down or in poorly lit places and on moving objects (such as vehicles). The lighting for reading is preferable to fluorescent lights.
(3) If there is dryness and redness in the eyes, a burning sensation or foreign body sensation, heavy eyelids, blurred vision, or even eye swelling or headache, stop operating the computer and reading books immediately and take a break.
(4) long operation of the computer and reading and learning visual fatigue symptoms, you can close your eyes and massage several points around the orbits, massage points specific methods are as follows: knead the eye point: eye point on both sides of the nose, about half a centimeter from the inner corner of the eye, with the ribbed surface of both thumbs pressed on the eye point, press the root part of the nose, first down after squeezing, squeeze up and down once for a beat, do four consecutive eight beats; knead the four white points : four white point in the lower edge of the orbit below the middle of the depression, with both hands index finger pressure, pressure surface is not too large, a press a loose for a beat, do four eight beats in a row; rub the solar plexus: solar plexus point between the outer corner of the eye and the tip of the eyebrow back about 1 inch, the ribbed surface of both thumbs pressed on the solar plexus, a press a loose for a beat, do four eight beats in a row. The entire massage process only takes about 2 minutes. You can also use a wet hot towel hot compress on both eyes, 15 minutes each time. If there is still no significant improvement through the above treatment, it is necessary to see an ophthalmologist at the hospital.
(5) Eye localization with hot compresses, medicine fumigation, physical therapy, acupuncture, etc. TCM ophthalmology believes that vision for a long time, resulting in excessive fatigue, or kidney yin deficiency, shortage of fluids, liver and blood deficiency, and internal depression and heat. Therefore, you can take internal Chinese medicine Qiju Dihuang Wan, Mingmu Dihuang Wan, Nourishing Blood and Tranquilizing Tablets, and Zhuangyao Wan. You can drop some eye drops to lubricate the eyeballs and relieve eye fatigue, such as Aivito eye drops, artificial tears, R&J, new Ladon, ZhenShiMing, R&S, Haibao, QingShiMing combination eye patch and other eye drops, it is recommended that you insist on using 2 – 4 times a day (with eye drops should not be fixed to use one, should be changed every 1 -2 months on the replacement of another eye drops).
8.Myopia prevention for teenagers
(1) When children start to read and study, ask them to use the correct posture so that the distance between the eyes and the writing is kept at 25 cm or more, and to develop good habits. The table used for reading and writing should not be too high. Make the vertical distance between the eye and the desk no less than 27 cm (the distance between the eye and the written determines the size of myopia and the time of continuous reading determines the speed of myopia development), and preferably control it at 27-33 cm.
(2) Before entering elementary school, the refractive state of the eyes and vision should be checked to see if they are normal, and if they are not, they should be immediately treated with glasses for correction.
(3) Starting from the first grade of elementary school, a pair of near-use glasses, specifically for long time reading and writing (such as doing homework) can prevent the formation of myopic eyes. However, the use distance should not be less than 25 cm (otherwise the prevention of myopia is ineffective).
(4) If the eye is already moderately nearsighted or above, in addition to appropriate glasses for correcting myopia, you should also have appropriate glasses for near use. Because the correction of myopia with glasses can not be used for a long time near (not to see near things, but will certainly aggravate the degree of myopia), naked eye reading (too close), can not replace the near glasses, but also aggravate the degree of myopia.
(5) reading and writing near the eye for a long time (more than 10 minutes), written to have a stable and appropriate light (preferably with a desk lamp. Daylight is good, but not stable) to ensure the stability of the eye and written distance.
(6) Should maintain adequate sleep time and outdoor aerobic exercise to improve physical fitness and anti-fatigue ability to maintain healthy retinal vision.
(7) It is important to establish the idea that prevention starts with a little bit and a moment and a scientific way of thinking. Because the prevention of myopia generation and development is not done once or twice or a day or two can be completed, and an hour at a time without prevention, can make myopia generation and development of one degree (0, 01 degrees).
9, three different from the previous methods of myopia prevention
(1) text method stiff head, or stiff shoulders will worsen blood circulation and indirectly lead to the decline of eye function. Using the head and neck, which is a combination of head movement and point-of-view movement, can naturally restore the above-mentioned healthy functions.
Training essentials: In a light-hearted state, open both feet shoulder-width apart and let your shoulders relax; look into the distance and shake your head to write. You can describe any article you like; eyes to match the activities of the face, move the point of view, do 20 minutes; be sure to match the rhythmic activities, you can put some music, naturally can be carried out in a relaxed atmosphere.
(2) long-distance running method to exercise foot strength can also strengthen the eyes. As the saying goes, fatigue starts from the feet and eyes, likewise, aging and fatigue both start from the feet and eyes. The symptoms of fatigue tend to appear in both the eyes and the feet. Whenever the feet feel tired, the eyes will be tired too. And vice versa. This interrelationship allows us to incorporate the long-distance running method into the overall training system.
(3) hot and cold method this is a hot and cold towel alternating eye compresses, for eliminating eye fatigue, promote blood circulation, stimulate the eye muscle and ease the stiffness of the external eye muscle has a very good help, can achieve the purpose of refreshing the eyes, revitalize the eye cells and enhance metabolic function.
Training methods: prepare two towels: a towel soak hot water to make the towel hot, the other covered in an ice pack or first refrigerated (wet paper towels can also be); sitting, standing, lying posture is not limited, relaxed body and mind, eyes closed; first fold the hot towel into the appropriate size, covering the eyes for 3 to 5 minutes, and then replaced with a cold towel, about 2 to 3 minutes clock. Alternating 2 to 3 times, the temperature to the eyes can accept as appropriate. Do this 2 to 3 times a week. It should be noted that hot compresses should not be applied when the eyes are inflamed, eyelids are red and swollen, keratitis, long needle eyes, pain or fever.
