Astigmatism is not a disease or anything to be scared of. It is a refractive condition, meaning there is a problem with how your eye focuses light. In a normal, healthy eye the lens is shaped like a sphere, has a fine focal point on your retina and can properly focus light. In an eye with astigmatism, the front of the eye or the lens in the eye is not completely round like a sphere. This makes part of the focal point either in front of the eye or behind the eye. Therefore, when light enters the eye it is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. As you can imagine, this leads to problems seeing clearly.
