In addition to myopia, which is a common eye problem, there are also astigmatism, farsightedness, refractive error, strabismus, etc. Today we will talk about the symptoms of astigmatism. It is very important to understand the symptoms of astigmatism, and only by knowing more about the symptoms of astigmatism as early as possible can we detect it early and take certain treatment measures, so that the treatment effect will be more obvious. The following we look at the symptoms of astigmatism it! 1, vision loss Sometimes vision loss is not only caused by myopia, many people will appear myopic situation, most of the time because of astigmatism. In general, the nature of astigmatism, refractive error and the direction of the axis will lead to vision loss, but because the nature of astigmatism, refractive error and the direction of the axis are different factors, so the degree of myopia are different. Astigmatism in the physiological range usually has no effect on near and far vision, so mild astigmatism does not affect normal vision. However, if there is a high degree of astigmatism or a combination of linear amblyopia or other abnormalities, it will lead to a significant loss of vision, but with timely correction can effectively restore good vision. 2, cone cornea Many patients suffering from astigmatism will be due to corneal crystal disease, which causes a variety of other eye problems, more common are cone cornea, corneal clouds, etc., and even some patients will also appear early age-related cataracts, etc., no matter which disease is very serious for patients, so should be detected as early as possible to treat. 3, visual fatigue People with astigmatism usually have varying degrees of vision loss, so at this time many patients often self-correct by changing the adjustment, squinting, squinting and other methods in order to better improve vision, but these adjustment methods can cause visual fatigue, especially some long-term ambulatory work or students, long-term correction of vision through this method, it will lead to The eyes are overworked, leading to a decline in vision. For some highly astigmatic eyes, the vision fatigue will not be obvious because they cannot improve their vision subjectively through efforts. But regardless of the situation, experts still remind patients that once astigmatism is detected, corrective and treatment should be carried out immediately. 4, lens curve differences Patients with astigmatism, regardless of the degree of astigmatism, the curvature of the cornea and lens meridians will be inconsistent in size, which is the most likely problem for all patients. Once there is an inconsistency in the size of the curvature of the corneal and lens meridians, the difference in the curvature of the horizontal and vertical meridians will be of different lengths, which will not only seriously affect vision, but also cause great damage to the eye. In daily life, we must pay special attention to astigmatism and prevent it, so as to better protect the health of the eyes. The symptoms of astigmatism should be understood and treated as soon as they are detected. After the initial understanding, we should also pay special attention to the fact that we must pay more attention to resting our eyes, especially computer people should look into the distance once every half hour. Only regular eye protection can make our eyes healthier and keep our own eyes away from diseases.
