In most patients hard contact lenses do a better job of correcting for astigmatism than soft contact lenses. But if any of its symptoms are present, astigmatism can be corrected by glasses or contact lenses. Small amounts of astigmatism can be ignored. The underlying causes are usually abnormal vessels that are leaking under the retina, damage to the macula, swelling or any. There are many possible causes, such as eye diseases, injury to the eye, eye infection, or inflammation. of conditions that occur when the cornea becomes thin and misshapen. It can also cause images to appear doubled, particularly at night. Distorted vision (aka metamorphopsia) makes straight lines appear wavy and objects to appear bent or misshapen. Keratoconus is a progressive eye condition that causes distorted, blurry vision. Rarely astigmatism is caused by lid swellings such as chalazia, and corneal scars, or by keratoconus (a rare condition in which the cornea becomes misshapen and pointed rather than smooth and rounded).ДЄstigmatism may cause blurred vision, eye strain or even headaches. Just as different people have different shaped feet or hands, people also have different shaped corneas. Astigmatism occurs when the cornea is curved more in one direction than another.ДЄstigmatism is quite common and, in the vast majority of cases, it is due simply to variations between people. The cornea should be curved equally in all directions. This irregularity can be the overall shape of the eye or the curvature of the cornea (the clear outer covering of the eye), or both. When the image is not focused, there is an irregularity in the eye. In order for the eye to work properly, light coming into the eye must be properly focused on the retina (or the back of the eye).
