The four "original sins" that ruin a child's vision are not computers or mobile phones, but they

As the saying goes, "The eyes are the windows of the soul". For a flowery child, this window is more like a gold rim and is very precious.

Every time I take my child to the hospital for a medical examination, the ophthalmologist always tells me something:

Children are still young. Parents should pay attention to the protection of their children's eyesight. Before the age of three, it is best not to let children watch mobile phones and computers, let alone for a long time. Because the blue light emitted by electronic products and the constantly changing images will stimulate the children's fragile eyes and affect the development of children's vision.

Well-known British biologists and psychologists advise parents: We should strictly control the amount of time a child sits in front of a television, just like restricting children’s intake of high-calorie junk food.

But many parents will still be confused:

Obviously, it has attached great importance to the protection of children's eyes, avoiding children's access to electronic products, and strictly restricting the time children spend playing mobile phones, but why does the child's vision still have problems?

In fact, the factors that cause children's poor eyesight are many. We often just see "surface factors" that endanger children's eyesight, and ignore the four "original sins" that affect children's eyesight!



Myopia is divided into physiological myopia and pathological myopia.

Physiological myopia mainly refers to myopia that occurs during development or after adulthood. It is essentially a refractive phenomenon, not an eye disease, so it will not be passed on to the next generation.

Pathological myopia occurs relatively early, usually occurs at the age of 5 to 10 years, and develops rapidly, it is difficult to correct. In adults, myopia may be as high as 1500 degrees, and this myopia will be inherited to children.

A survey shows that if the parents of the child are myopic, then their child has a 33% chance of becoming a myopic. However, parents should not worry too much. Pathological myopia is very rare in myopia, accounting for only 2%. Most people are only physiological myopia, not hereditary.


environmental impact

In addition to congenital genetic factors, the impact of the environment on children's vision can not be ignored.

For example, when bathing children in winter, they worry that their children will catch cold. Many parents will turn on the bath heater, or prepare a small solar heater for their children. But in the process of bathing, the children's restless little eyes will always stare at the glowing and hot things.

Because the light emitted by the small sun and Yuba is infrared radiation, long-term direct vision will stimulate the delicate eyes of the child, it is easy to cause lens injury, and cause great damage to the child's vision, and this damage is irreversible. Therefore, parents should pay special attention.

In addition, turning on the lights to sleep will also affect the child's vision.

Turn on the lamp to sleep, the light source of the light will cause certain pressure and irritation to the eyes, which not only makes the child agitated difficult to fall asleep, but also affects the child's visual development.

Studies have shown that before 2 years old, the rate of myopia in children who sleep in a room with a night light turned on is 1.24 times that of those who do not turn on the light; the rate of myopia in children who sleep in a room with a headlight turned on is 1.45 times that of a person who does not turn on the light.


Give your child too much sugar

Parents all know that eating too much sugar content is bad for children's teeth, not only that, when the baby consumes too much sugar, his vision will also be affected accordingly.

Because sugar is metabolized in the body, it needs to consume a lot of vitamin B1, and will reduce the calcium content in the body.

Vitamin B1 has a protective effect on the human optic nerve. If the child lacks this vitamin, the conduction of the optic nerve will be impaired, which will lead to the decline of the child's vision; and calcium is the "protector" of the eye tissue. , It will cause the elasticity of the retina to decrease, the pressure of the lens will increase, and myopia is easy to occur.

For the sake of children's eyesight, not only the child's diet needs special attention, but before the child is born, the diet of the pregnant mother is also very important.

Now that living standards have improved, the diet of pregnant mothers will become more refined, and coarse grains will also be replaced by fine grains, resulting in the gradual reduction of vitamins that are beneficial to fetal eye development. A high-sugar diet enters the pregnant mother's table, which also increases the likelihood of the child suffering from myopia in the future.

Therefore, in order for the child to have a good vision, whether during pregnancy or after the child is born, parents should avoid letting the child consume too much sugar.


Lack of outdoor sports

With the emergence of a variety of electronic products that cater to children's tastes, the time that children should go out to play is completely occupied by electronic products. After years of excessive eye use and eye fatigue can not get rest, the children's myopia becomes more and more serious.

Some survey data show that the average child who goes out for 3 hours a week is 9 times more likely to have myopia than the child who goes out for 14 hours a week.

Ophthalmologists also revealed that appropriately increasing children’s outdoor activities and exposing children to natural light is an effective way to prevent myopia.

Because the bright natural light outdoors can stimulate the pupils of the child and make the eyeballs stronger and stronger, more exposure to outdoor light can also promote the secretion of dopamine agonists by the retina. This substance can effectively prevent the growth of the child's eye axis and prevent myopia.

Take good care of the children's eyes, and the parents have no problem.

From now on, pay attention to the child's eye hygiene, avoid the child's long-term eye use, help the child develop good eye habits, and regularly take the child for visual inspection to keep the child away from myopia and have a pair of bright eyes.
