What are the causes of astigmatism in children's eyes

Factor 1: astigmatism is caused by corneal curvature. Under normal circumstances, the cornea is uniform and transparent. The cornea is the outermost layer of the eyeball, and light first passes through the cornea and then enters the eye. We can compare the cornea to a transparent glass with uniform curvature. When light passes through it, there will be no refraction and other deviation. After adjustment by the lens, it can present a clear image on the retina, that is, there is only one clear focus.

Factor 2: astigmatism is caused by the curvature of the cornea. That is, the layer of "uniform glass" is concave and uneven. As a result, after the light passes through the cornea, it presents two blurred images on the retina, that is, there are two blurred focuses. That's why you don't see clearly. So people with astigmatism see things with double shadows.

Factor 3: astigmatism of baby's eyes is generally caused by congenital eye dysplasia. In life, if children watch TV and read books for a long time, it is easy to cause more serious eye fatigue, which leads to an increase in the degree of astigmatism. However, myopia, hyperopia or amblyopia are often accompanied by astigmatism. If children like to squint and squint, their parents should pay special attention to it and check it immediately through professional institutions.
