Astigmatism <\/strong>\u2013 Sounds like a big scientific term or a serious disease, isn\u2019t it? Neither an eye disease nor a vision problem, astigmatism is just a refractive error caused due to irregular shaped lens and can be easily corrected. So if your eye-doctor tells you have astigmatism, relax!<\/p>\n\n\n\n\n\n\n\n

Usually a normal cornea appears completely round as football but astigmatism cornea appears like a rugby ball. Since the curvature is asymmetrical, the objects appear blurred both far and near. The astigmatism eye faces problem to focus on light. The light falls on multiple focus points, sometimes in front of retina or behind retina or both.<\/p>\n\n\n\n

What causes Astigmatism? <\/h4>\n\n\n\n

Some people are born with astigmatism, it is mostly inherited. If any of the parents have astigmatism, then the child is likely to have too. Anybody who already has vision problem like nearsighted or farsighted can also develop astigmatism which requires to be corrected. Sometimes it develops after any eye injury or operation like cataract. Since this eye imperfection mostly occurs in early stage of life, it is necessary to get detected with proper eye exam to avoid vision problem in future. <\/p>\n\n\n\n

Astigmatism symptoms:<\/h4>\n\n\n\n

Blur vision is one of the common problems. Person with astigmatism can see objects either distorted or blurred across all distances. Ignoring astigmatism, may cause strain to eyes while performing any visual activities and also cause headache. Excessive squinting of eyes is also a common symptom observed in people with astigmatism. Sometimes it might be difficult to identify if you have astigmatism buy if you experience any of the above symptoms, it will be sensible to get your eyes examined without delay.<\/p>\n\n\n\n

Astigmatism test:<\/h4>\n\n\n\n

Astigmatism is quite common among children as well as adults, however you might not realise until you get your eyes tested. If you leave undiagnosed, you might find difficult to concentrate, read or clearly view objects. It is necessary to stay aware of any changes in vision hence you must have an eye check-up at regular intervals. For children it is recommended to get eye test every year while for adult once in two years. The normal eye-checkup will get your astigmatism tested too.<\/p>\n\n\n\n

Types of Astigmatism: <\/h4>\n\n\n\n

\nThere are actually many types of astigmatism with somewhat similar \nsymptoms. You should be aware of the different types of astigmatism. \nTill now, numerous types of astigmatism have been identified, but the \nthree primary types include:\n\n<\/p>\n\n\n\n

Myopic<\/strong>
Myopic astigmatism is a type of astigmatism where light comes to two focal points. The light rays are brought to a focus in front of the retina. One or both the key meridians of the eye are nearsighted. In case if both the meridians are nearsighted, then they are myopic in differing degree. <\/p>\n\n\n\n

Hyperopic<\/strong>
Hyperopic astigmatism is a condition where the objects are being focused behind the retina. One or both of the principal meridians are farsighted. In case if both the meridians are farsighted, then they are hyperopic in differing degree. <\/p>\n\n\n\n

Mixed<\/strong>
Mixed astigmatism is a refractive error where the light ray is not clearly focused on retina. In this type of astigmatism, one principal meridian is myopic (nearsighted) while the other is hyperopic (farsighted). <\/p>\n\n\n\n

Astigmatism is also categorised as regular and irregular astigmatism:<\/em><\/p>\n\n\n\n
