How is astigmatism caused in children? Nowadays, children have more and more eye problems, especially astigmatism, which is also called confusion. Astigmatism is a common eye disease and a manifestation of eye refraction. Do you know how children's astigmatism is caused?

How is astigmatism caused in children? 1 Astigmatism in children is mostly related to congenital factors. The incidence of astigmatism in children and adolescents is significantly higher than that in those whose parents have no astigmatism, which shows that they have certain genetic susceptibility. Some environmental factors include the following:

A, such as disease, trauma, surgery, etc. , can lead to corneal or lens refractive changes and cause astigmatism.

Secondly, the tension of extraocular muscles and the pressure of eyelids will also affect the shape of cornea, leading to astigmatism.

Third, bad eye habits and lack of outdoor activities may also promote the formation of astigmatism.

Fourthly, the study also found that the detection rate of astigmatism in obese children and adolescents is higher than that in normal children and adolescents.

Five, some nutritional factors, malnutrition leads to a decline in corneal hardness, increasing the risk of corneal astigmatism.

Six, some special diseases, such as Down syndrome, Treeher syndrome, spina bifida, nystagmus and other diseases, patients also have a higher risk of astigmatism.

How is astigmatism caused in children? 2. Congenital.

First of all, this is probably caused by abnormal corneal curvature, which is closely related to upper eyelid compression. Sometimes it is also called physiological astigmatism, and the degree is relatively light. This astigmatism will gradually ease with the increase of age, but the change range is not particularly large.

Second, poor eye posture

Some children have bad eye posture for a long time, such as always squint or rubbing their eyes with their hands, and the eyelids press the cornea, which will also change the curvature of the cornea and aggravate the degree of astigmatism. In order to correct this astigmatism, parents must let their children get rid of bad habits and try not to touch their eyes with their hands.

Third, use your eyes too much at close range.

Nowadays, many children especially like watching TV and playing computer, because their eyes are very adaptable and they will adjust themselves to this short distance. If they use their eyes for a long time at close range, it will increase the burden on their eyes, which will not only cause myopia, but also cause astigmatism for many children. Such children must often take part in outdoor sports, watch TV in the room for half an hour and then go out for a walk, so that their eyes can adjust to see things at different distances and adjust the ciliary muscles.

Fourth, light.

If the lighting at home is too dazzling, it will make children's eyes tired, and there are many good books now, which will actually hurt their eyes, especially at night. This dazzling light is called glare in medicine.

How is astigmatism caused in children? How is baby astigmatism caused? One: congenital.

1, reason:

It is mainly caused by abnormal corneal curvature, which may be related to upper eyelid compression, sometimes called physiological astigmatism, and the degree is very slight (25-50 degrees).

2. Tips:

This astigmatism may decrease slightly with age, but the change is not significant.

How is the baby's astigmatism caused? 2. Poor posture with eyes.

1, reason:

Long-term bad eye posture (such as squinting, rubbing eyes, lying down reading, etc.). ), the oppression of the eyelids on the cornea will also change the curvature of the cornea and increase the degree of astigmatism.

2. Tips:

Giving up bad habits is a way to prevent astigmatism and myopia. And these habits are often the cause of myopia, so some people think that myopia will cause astigmatism, in fact, the two have nothing to do. When the focus of parallel rays entering the eyeball is not on a cross section, it is called astigmatism.

How is the baby's astigmatism caused? Three: Too many eyes at close range.

1, reason:

Children spend most of their time indoors, so the chances of watching TV and playing computer will increase, and their eyes are very adaptable and they will adjust themselves to this short distance. Long-term close use of the eyes, the eye burden is very heavy, it is easy to cause astigmatism.

2. Tips:

Let the baby do more outdoor activities. When doing outdoor activities, the eyes will automatically adjust to see things at different distances, and the eyes will be used alternately far and near, so that the ciliary muscles of the eyes can be adjusted without fatigue.
