Symptoms of astigmatism

summary

Astigmatism is an eye disease. In our daily life, we often encounter astigmatism patients. So, what are the symptoms of astigmatism? Astigmatism is a kind of eye disease which does great harm to eyesight. When suspected astigmatism symptoms are found, it should be actively corrected in time. Astigmatism symptoms mainly in the following aspects.

Symptoms of astigmatism

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.

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. It's hard to see far and near, but it's hard to blame close work for a longer time, that is, eye distension, headache, reading or double shadow.

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.

matters needing attention

Although serious astigmatism makes people not see clearly, astigmatism of low degree also plays a certain role. Astigmatism below 75 degrees helps to see the distance clearly. Beyond this degree, the distance will be blurred. Therefore, if the astigmatism degree is below 75 degrees, it is not necessary to add the function of astigmatism correction on the lens. Laser myopia surgery can also treat astigmatism.
