Astigmatism?

summary

Astigmatism is a kind of abnormal refraction of the eye, which is related to the curvature of the cornea. The human eye is not perfect. The cornea of some eyes is curved at one angle, while the cornea of others is flat. Astigmatism? Next, I'd like to share my views with you.

Astigmatism?

Normal head position and eye position: in order to see more clearly, people with highly asymmetric astigmatism often take tilted head position, resulting in strabismus, which can be recovered after astigmatism correction. People with high astigmatism often squint when they look at distant objects to achieve pinhole and fissure effect, so as to improve their vision. Through pinholes or cracks to see things, you can reduce the impact of astigmatism on vision.

Blur: blurred vision is closely related to the degree and manner of astigmatism. People with mild astigmatism usually have normal vision, but they may have headache, eye fatigue and blurred vision when looking at objects at a certain distance. People with severe astigmatism have blurred and distorted vision. I don't know how to look far and near, but I work close for a long time, i.e. eye distension, headache, reading or double shadow

Visual fatigue: the blurred image on the retina needs to be adjusted constantly, and the vision is distorted, so astigmatism, especially hyperopia astigmatism, is prone to visual fatigue. Young people with compound hyperopia and astigmatism can often make up with adjustment. According to the degree of adjustment, they can form pseudo simple hyperopia astigmatism, pseudo simple myopic astigmatism or pseudo compound myopic astigmatism.
