Astigmatism in children?

summary

Astigmatism is a kind of abnormal refraction of the eye, which is related to the curvature of the cornea. My own eyes are a little short-sighted and astigmatism and strabismus, so I have a certain understanding of these. Astigmatism is caused by the different ability of the eyeball to bend light in different directions. The refraction of myopia, hyperopia or normal eyes is like football and basketball, while the curvature of astigmatism is like football. Some directions are more tortuous and some directions are less tortuous, so the imaging can not be a point. Astigmatism in children? Let's talk about it.

Astigmatism in children?

Astigmatism is usually born, if your astigmatism is relatively high, and you did not have glasses when you were a child, then, from small to large, you see things are more fuzzy, but because they do not compare, so it is more difficult to detect than myopia and hyperopia. When people are born, their eyesight is relatively poor. To get full development, they rely on the refractive system to project clear images to the retina to stimulate fundus development.

People with high astigmatism see far and near blurred, the fundus is not fully stimulated, will not be fully developed, resulting in amblyopia. If you can't see 1.0 with optometry and glasses, then you have amblyopia. If you are more than 10 years old, then it is beyond the period of visual development, amblyopia treatment is basically ineffective.

General astigmatism has the following characteristics: 1. Blur: blurred vision is closely related to the degree and manner of astigmatism. Slight astigmatism is usually hard to detect, but when you look at something at a certain distance, your eyes will be swollen, tired, blurred vision, and even headache. Severe astigmatism can't distinguish between near and far. 2. Visual fatigue: for the blurred image on the retina, it needs continuous fine adjustment, coupled with the distortion of the visual object, it will be more tired after a long time. 3. Normal head position and eye position: in order to see more clearly, people with high asymmetric astigmatism often take tilted head position, resulting in strabismus.

matters needing attention

In order to accurately diagnose astigmatism, we usually need to go to a regular hospital for astigmatism examination. There are many ways to check astigmatism, and the commonly used one is astigmatism meter. Astigmatism watch is like a clock dial with many radiation lines. The normal eye can see every line on the astigmatism table clearly, but the astigmatism eye can only see some lines clearly and thickly, while the other lines are blurred and pale. Professional Optometrists can use their own techniques and methods to check the astigmatism and axial direction.
