What is regular astigmatism, and how to know that the shadow does not affect visual impairment

Regular astigmatism generally refers to the abnormal refractive state caused by the inconsistent curvature of the meridians on the surface of the cornea or lens. Whether it affects visual impairment needs to be judged on a case-by-case basis.

1. Concept

Regular astigmatism is caused by the fact that the refractive power of the eye is different on different meridians, resulting in the phenomenon that the parallel rays cannot form one focal point but two focal lines after passing through the refractive system of the eye, resulting in the phenomenon of scattering. Astigmatism is a common eye disease that can be divided into two types: myopic astigmatism and farsightedness.

2. Influencing factors

1. Myopic astigmatism: If the patient has myopic astigmatism, it may have a certain impact on the patient's vision, and it may also affect the patient's normal life. It is recommended that patients seek medical treatment in a regular hospital in time and wear glasses for correction under the guidance of doctors.

2. Farsighted astigmatism: If it is farsightedness, it usually does not have much impact on the patient's vision and does not cause obvious uncomfortable symptoms. However, if you do not pay attention to eye hygiene, your eyes may be infected by bacteria, which may induce diseases such as conjunctivitis and keratitis, which will affect the patient's vision.

In daily life, patients should pay attention to the rational use of their eyes and avoid looking at electronic products at close range for a long time, so as not to aggravate astigmatism. At the same time, it is also necessary to maintain a good attitude and avoid getting too emotional. If you feel obviously unwell, you should go to the hospital for treatment in time.
