1, "With glasses, the degree will get deeper and deeper?" Many parents have this view, but this view is actually wrong, because as long as the cause of myopia is still there, the degree of myopia will continue to deepen, which is not directly related to whether or not to wear glasses. Once you find that your child is nearsighted, you should see a doctor as soon as possible, and with the help of the doctor, you should optometry your child.

2. Some parents think: "If parents have good eyesight, children will not be nearsighted?" Although myopia is related to heredity, it mainly depends on the acquired eye habits.

3. "Teenagers need to wear glasses without treatment?" Glasses can only inhibit the development of myopia. What parents should do is to take correct and effective corrective measures to prevent and control the growth of children's myopia.

4. Parents are highly myopic, and children are more prone to myopia. As an adult, the degree of myopia will be relatively stable because of slow growth and development.

These habits that hurt the eyes should be avoided.

1, loves sweets

Many parents can't think of it, can they? Children's love of sweets may not only hurt their teeth, but also contribute to the occurrence and development of myopia. Sweet food intake will consume a lot of vitamin B, affect the normal metabolism of retina, reduce blood calcium content, affect the development of eye wall and change the osmotic pressure of lens. On the whole, it is a bad influence on vision.

2. Nutritional imbalance

The development of eyeballs, like the physical development of children, needs balanced nutrition. Taking vitamin A or carotene can prevent dry eye and avoid night blindness and dry eye.

Foods rich in vitamin A include broccoli, carrots and mangoes. Vitamin B group is an indispensable component in vision care, which can be taken from animal liver, dairy products, lean meat, green leafy vegetables, beans and brown rice.

3, improper use of lighting

Many children like to turn off the indoor lights and use desk lamps when doing their homework at night. Or, be sure to turn off the lights when watching TV. Or, squint and study in the dim light.

This leads to uneven indoor light distribution and affects the development of children's visual function. In addition, if the color of exercise books or textbooks and books is too white, it is easy to form a huge contrast under the irradiation of desk lamps, which will affect vision.

4. Incorrect sitting posture

Maintaining an incorrect sitting posture for a long time is extremely harmful to the eyes. Especially for children who need to sit and study for a long time, if they sit incorrectly, they will be nearsighted in minutes.

Playing mobile phone in bed, watching TV on sofa and doing homework at desk have become three typical reasons for teenagers' myopia. In addition, long-term sitting posture is not correct, which easily leads to different visual stimulation intensity of children's eyes and different visual development degree of eyes, thus leading to different visual acuity of eyes.

5, lack of sleep time

Lack of sleep is also one of the important reasons for children's myopia. Teenagers whose bodies are developing may lead to nervous disorder if they don't get enough sleep. As far as the eyes are concerned, they are in a state of lack of sleep for a long time, and the nerves of the eyes are too tired and prone to dysfunction, which is the pathological basis of myopia.

6. Wear bad sunglasses

Children, especially children's eyes are delicate and vulnerable to strong light. In this sense, children need to wear sunglasses. However, it should be noted that children under 6 years old should not wear sunglasses for a long time, because their visual function development has not yet reached the adult level, and wearing sunglasses for a long time may form amblyopia. The correct way is to put it on children when the sun is strong, and take it off in time when the sun is weak or indoors.

At present, the children's sunglasses market is mixed. If the sunglasses we buy have quality problems, it will not only induce children's myopia, but also cause other diseases.

7. Wear a pair of glasses until your leg is broken

Glasses are one of the most common and safest choices to correct vision. However, in order to save money, some people not only don't change a pair of glasses for three to five years, but some even wear them with broken legs. On the surface, it seems that they have saved a few glasses, but they don't know that glasses also have a service cycle. The longer they wear them, the greater the damage to their eyesight.

8. Lack of outdoor activities/excessive sun exposure

Many children don't like outdoor activities. Because their eyesight health needs the adjustment of sunshine and outdoor activities, if children stay at home all day and night, it will cause unexpected damage to their eyesight for a long time.

But it's not as hard as possible. Although vision health can't be separated from sunlight, too much sunlight can also do harm to vision, because ultraviolet rays in sunlight can lead to eye diseases such as wrinkles around eyes and cataracts.

9, excessive use of eyes

Of course, the last point that everyone is most likely to notice is the problem of "excessive use of eyes". Nowadays, children not only have homework every day, but also have the temptation of computers and mobile phones, and they use their eyes almost all the time. Staring at the blackboard in class and staring at the book after class, I finally have a break. I want to watch videos and play video games for a while. How can my eyes rest?

Ophthalmologists have these suggestions.

There are two reasons for myopia: one is environmental factors, and the other is genetic factors. At present, what people can control is environmental factors.

We should have the consciousness that we should pay attention to the development of vision and avoid using our eyes too early. Preschool is a critical period for eye development. If you use your eyes too much at this stage, it will have a bad effect on your child's eyes. At this preschool stage, children should not be allowed to read, write, draw and play computer games too much, but should participate in outdoor activities, such as playing ball games and dancing, so as to avoid premature myopia.

Intervention: Do you need glasses or not? Do not be blind.

Adolescent myopia is mostly "pseudomyopia" at first, which is a kind of functional myopia caused by excessive use of eyes. If you don't intervene in time, you will soon develop into real myopia. Therefore, when children's eyesight is found to be declining, parents should not rush to give their children glasses. First of all, they should have mydriatic optometry to distinguish true myopia from false myopia. For children with true myopia, you can choose cheap frame glasses.

Exercise: Strengthen outdoor exercise, 2 hours a day.

To protect children's eyesight, in addition to maintaining good eye habits, two hours of outdoor activities every day must be indispensable. From an early age, we emphasized that we should pay attention to the combination of work and rest when studying, and avoid using our eyes at close range for a long time. No matter how heavy your studies are, you should leave enough time for outdoor farsightedness, outdoor activities and physical exercise, because even if you don't read books, the field of vision in the room is only a few meters, and staying indoors for a long time will also weaken your eye adjustment ability.

In addition, in hot summer, air conditioners and fans are everywhere. In such an indoor environment, dry air will accelerate the loss of water in the eyes and easily cause dryness and edema in the eyes. So don't stay in this environment all the time, go out as much as possible.

Play badminton and table tennis more. In the process of playing, the eyes must quickly follow the trajectory changes of flexible "small ball movements" such as badminton and table tennis, which is of unexpected benefit to the improvement of eyeball function of children aged 5-9.

Habit: Develop good habits and use your eyes scientifically and reasonably.

Posture: Cultivate children's correct reading and writing posture. Don't lie prone on the desk or twist your body to write. Put your book and eyes in a square foot, put your body a fist (adult) away from the desk, and put your hand an inch away from the pen tip. School desks and chairs should be suitable for students' height changes. At the same time, it is also necessary to prevent children from hiding in bed and reading books before going to bed. In addition, don't write too small and too dense. Don't write italics or cursive characters.

Reading and writing time should not be too long. After 30~40 minutes of continuous eye use, rest for 10 minutes, look far away, usually look at more green plants and do eye exercises. Writing and reading should have proper light, preferably from the left. Too strong light will make children's eyes feel tired easily. What children need is soft light. Make sure the light comes from the left front of the child. Therefore, when reading and writing at night, children should choose a lamp with adjustable brightness, and adjust the brightness softly, or use a light source without stroboscopic light, a desk lamp for reading and an ambient light source.

Pay attention to the height and distance when watching TV. The height of the TV should be level with the line of sight; The distance between the eyes and the screen should not be less than 5 times the diagonal length of the screen; When watching TV, turn on a soft little light indoors, which is beneficial to protect your eyesight; Watch TV for 30 ~ 40 minutes, and operate mobile phones and tablets for more than 15 minutes. You should take a short rest or do eye exercises.

Food: These foods are good for protecting eyes.

Eat more foods rich in B vitamins, all kinds of vegetables, animal livers and egg yolks. Carrots contain vitamin B, which is good for eyes; Eating more animal liver can cure night blindness. Myopia patients generally lack chromium and zinc, so they should eat more foods containing zinc and chromium, such as soybeans, almonds, seaweed, kelp, mutton, yellow croaker, milk powder, tea, meat, beef and liver. It is best to take protein zinc for zinc supplementation; Eat less food with high sugar content.

It is essential to have an eye examination every six months. Establish refractive development files for children. If you don't have myopia, you need to have your eyes checked every six months. If there is a risk of high myopia (such as parents' high myopia, long close eye contact time and little outdoor activities), it is recommended to have a physical examination every 3-6 months. The eyes are the windows to the soul. Spark hopes that parents and children must pay attention to protecting their eyesight and protect this "window".
