Astigmatism is a refractive error of the cornea or lens of the eye. This is due to the curvature of the cornea or lens of the eye is not uniform. Possibility your complaint is related to the cylindrical eye disorders.
Abnormalities reftaksi on astigmatism cause shadows fall not at one point, eventually causing objects appear blurred. This happens because of the curvature of the cornea or lens that is not symmetrical like a ball.
Normal eye would have a uniform surface in each direction, but the astigmatism are several areas on the surface of the partially flat or inclined in. URLs such as egg or rugby ball (normally like a ball). This situation causes the light entering the eye will not refracted at the focal point so that the object being viewed is not clear and shaded.
In general, astigmatism occurs at birth (genetic) and others because of trauma, disease or a history of eye surgery
To fix can be given assistance cylindrical lens glasses. Giving glasses are cylindrical lens does not change the shape of the eyeball that already exists, but it helps to keep the rays entering the eye to be refracted at the focal point of the object being viewed and then became clear. However, technological advances give hope to perform LASIK refractive surgery, that is by changing the uneven curvature becomes flat.
