What is eye astigmatism?

Myopia is a very common eye disease. It should be noted that many myopic patients have some degree of astigmatism, which makes people see objects blurry and easily causes visual fatigue, which requires our attention. Eye astigmatism poses a great threat to research institutions and requires our attention. So, what is astigmatism?

There are many manifestations of eye astigmatism. People will experience decreased vision and dizziness and eye soreness after looking for a long time. We need to take good care of our eyes and check and treat them in time when any discomfort occurs.

What is astigmatism? The reason for astigmatism is that the uneven thickness or curvature of the cornea makes the refractive rates of the corneal meridians inconsistent, so that the light passing through these meridians cannot be focused on the same focus. Therefore, patients should be very careful when treating children with astigmatism. The treatment of astigmatism in children mainly depends on the quality of vision and the severity of visual fatigue. If the child has regular astigmatism, does not cause visual impairment, and has no visual fatigue, no treatment is needed. If children have visual fatigue, no matter how large or small the astigmatism is, even if the astigmatism is very slight, they need mydriasis refraction and wear appropriate corrective glasses. This is very important for the treatment of children's astigmatism. The treatment of astigmatism in children should be timely, and preventive care for astigmatism should be done.

What are the methods to prevent astigmatism?

1. There should be sufficient light when reading, and the light should preferably come from the left rear; the reading posture should be correct and the distance should be maintained between 30 cm and 40 cm. Don't read in a rocking car or while lying down.
