How is child eye astigmatism to return a responsibility?

summary

In daily life, astigmatism is a state of ametropia. Siming hall experts pointed out that due to the complex symptoms of astigmatism, the causes of astigmatism are also very complex. Many people can't get better after a long time, not because they can't get better, but because they don't understand it. Let's introduce how children's astigmatism is going on?.

How is child eye astigmatism to return a responsibility?

First: curvature astigmatism: caused by abnormal changes in corneal curvature. If the meridian with the largest refractive power and the meridian with the smallest refractive power are perpendicular to each other, regular astigmatism is caused, which is mostly congenital, and the degree of astigmatism is large. If the surface of the cornea is irregular deformation, uneven bending, unable to form a focus on the retina, it is called irregular astigmatism, such as corneal traumatic scar, keratoconus, corneal degeneration and so on.

Second: refractive rate astigmatism: it is caused by the change of refractive index of lens. Astigmatism degree is generally small, such as senile cataract, lens cortex water gap, feathery opacity, resulting in changes in the refractive index of the lens, can form astigmatism.

Third: eccentric astigmatism: previously seen in crystal displacement, such as congenital deviation, crystal subluxation, etc.

matters needing attention

Therefore, don't let astigmatism accompany your child for a lifetime. Having a bright and fresh future is the best gift for your child!
