Astigmatism will be more serious with glasses.

There is only one reason, that is, glasses are not allowed, such as wearing glasses without accurate optometry.

So if your eyes have astigmatism, you must go to a regular hospital for optometry. Only accurate optometry can understand the degree of astigmatism, and the glasses you wear are more accurate. You can see clearly and comfortably after wearing glasses. Therefore, if your eyes have astigmatism, don't try on your glasses in an optical shop or medical institution without medical qualifications. If it is not accurate, it will not only confuse things, but also have a more serious impact on the eyes, such as eye fatigue or myopia.

Astigmatism is due to the irregular development of corneal morphology, which is not a regular sphere but an ellipsoid, resulting in different refractive power in vertical and horizontal directions. After the external light enters the eye through corneal refraction, it cannot form a perfect focus on the retina, but a focal line. The projection on the retina is blurred, which leads to decreased vision. It can be caused by one eye or two eyes, especially two eyes. After suffering from astigmatism, the main symptoms are blurred objects in the distance, relatively clear objects in the vicinity, and slight deformation of things. There is a virtual shadow at the edge of the object and a halo at the light source.

Correcting astigmatism requires wearing a cylindrical lens to correct refractive differences in different directions to form a focus, so as to achieve the purpose of obtaining clear vision. If patients without astigmatism wear astigmatism glasses, the light can't form a focus after entering the eyes, and they can't see clearly. If it is only worn for a short time, it generally has little effect, but when it is worn, it will feel unclear and ghostly. But if you wear it for a long time, it will cause visual fatigue, and even lead to the formation or aggravation of myopia or astigmatism.

Therefore, patients without astigmatism should not wear glasses that are not suitable for their own degree, which will not only improve their eyesight, but also cause harm to their eyes. If they need glasses for myopia and other reasons, they must match them according to their own degree.
