My child has astigmatism, when should glasses be worn? Can it go back to normal?

Our brain receives external information through five senses every day. The proportion of them receiving external information is: taste 1%, touch 1.5%, smell 3.5%, hearing 11%, and vision 83%. If the eye, the largest organ of visual reception, has a problem, it will seriously hinder the efficiency of receiving information from the outside world. Therefore, we must pay attention to the real condition of the eyes, especially the eyes are still in the childhood stage of growth and development. Today, let's talk about an important condition that affects children's vision: astigmatism.

1. What exactly is astigmatism?

We all know that the shape of the eye is spherical. The light from the outside world is refracted by the cornea and lens to form an image on the retina, which allows people to see the object or other people in front of them. However, the surface of the cornea or lens of some people's eyeballs is not a perfect arc curve, but like a pitted mirror, which will prevent the incoming image from forming a clear "image" on the retina, which is the astigmatism that hinders the reception of information. main source. There are many reasons for astigmatism, one may be congenital abnormal development of the cornea or lens, another may be the wrong posture when reading and writing, which may squeeze the cornea, and the third may be caused by eye surgery or corneal disease. Almost everyone has different degrees of astigmatism, but most people have a low degree of astigmatism that can be ignored. Very few people's astigmatism will change with age, and the degree of astigmatism will change. Children's astigmatism is mostly natural. The standard for judging astigmatism is the severity of astigmatism, which requires the help of professional instruments to accurately diagnose. According to the degree, it can be divided into mild (≤ 2.00 D), moderate (2.25-4.00 D), and severe (> 4.00 D) astigmatism. Below 1.00 D is generally considered to be physiological astigmatism and does not require special treatment.

2. What should I do if my child is found to have astigmatism?

In terms of pathogenesis, astigmatism will not get better on its own, and timely and effective intervention is required. If the child's astigmatism is relatively light and has little impact on life and learning, you can temporarily observe it without wearing glasses. Pay attention to taking the child to the hospital for re-examination on a regular basis, and cultivate good eye habits. If the child's astigmatism is moderate, although it will not cause amblyopia, not wearing glasses may have a greater impact on the child's life and learning. In this case it is recommended to wear glasses for vision correction throughout the day. If the astigmatism is relatively high, it is not only a problem of unclear vision, but may also lead to amblyopia. Therefore, parents must pay attention to it, especially before the child is 8 years old, it is the best time to treat amblyopia. Correction becomes much more difficult after age because vision development in the brain basically stops after age 8. Young children with astigmatism are recommended to wear frame glasses. When children are fifteen or sixteen years old, they can try to wear contact lenses. After the age of 18, laser surgery can be used to correct astigmatism. However, because the eyes themselves are relatively fragile, the recovery time will take about 2 to 3 months. At the same time, it is necessary to avoid bad eye use methods at all times, which will affect the effect of the operation.

3. Can astigmatism in children be prevented? Can it be completely cured?

Because most children's astigmatism is congenital, there is no way to prevent it in advance, only corrective treatment can be performed after the symptoms are found and the test results are confirmed. As for whether astigmatism can be completely cured or returned to normal, this is the most concerned issue for parents, unless there is a method, which is the laser surgery we mentioned earlier. In fact, astigmatism itself is not so terrible, but because many parents have little knowledge about this aspect, especially when they think that their children will wear glasses at such a young age, they are very anxious. In fact, under normal circumstances, even if children wear glasses, it will not have much impact on life and learning, and the purpose of wearing glasses is to better protect children's eyes and reduce more damage. Therefore, instead of worrying about children wearing glasses, it is better to pay more attention to children's eyes and help children develop good eye habits.
