What are the main symptoms of astigmatism?

summary

When testing eyesight in daily life, some people will have astigmatism, which is actually a very common problem, because when this happens, multiple imaging objects will appear in the eyes of patients, and astigmatism can be divided into two categories according to different causes, namely irregular astigmatism and regular astigmatism, Generally, astigmatism does not exist alone. Most astigmatism will be combined with hyperopia and myopia, and the higher the degree of hyperopia and myopia, the greater the possibility of astigmatism. For the treatment of astigmatism symptoms is also different, for the impact on vision is not particularly big, generally do not need treatment, but cause eye fatigue will be treated. Let's see what symptoms astigmatism can have. 　

What are the main symptoms of astigmatism?

Astigmatism patients because far away from the focus line of the retina, the color of the visual object will become pale, the edge will be blurred, vision will decline, serious patients will have diplopia. In addition to physiological astigmatism, all kinds of astigmatism are easy to cause visual loss. The vision of hyperopic astigmatism is better than that of myopic astigmatism due to its regulating effect. For example, the same is 1.00 degree astigmatism, hyperopia astigmatism vision is generally about 0.8; The visual acuity of myopic astigmatism is about 0.5; When looking at the sight mark with oblique astigmatism, the sight mark is easy to deform“ The phenomenon of "long hair" often results in vision loss due to deformation. Therefore, it is particularly important to correct the axial position of oblique astigmatism.

Astigmatism patients with vision loss, whether looking at the distance or near all feel blurred. Children often close their eyelids half closed and squint into a gap in an attempt to make the object see more clearly.

As astigmatism eyes can not focus, the brain is easy to produce selective interpretation of the image. In addition, in order to see the scene clearly, astigmatism eye should use adjustment as much as possible to reduce the size of the diffusion circle to improve the image quality; If high astigmatism is not corrected properly or does not wear glasses, it is easy to cause headache. Asthenopia and other symptoms, so astigmatism is easy to produce asthenopia.

matters needing attention

After getting astigmatism, it will generally lead to the decline of vision. When seeing things, it always feels that the edge is empty. When it is serious, it will also lead to diplopia, which seriously affects the vision of patients. In addition, astigmatism will lead to patients always half squint to see things, and will also produce visual fatigue.
