Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause blindness.
Astigmatism can be corrected with glasses, contact lenses, or refractive surgery (i.e. laser eye surgery), although treatment may not be necessary if the symptoms are mild. Glasses and contact lenses both compensate for the irregular shape of the cornea and help to focus light properly into the back of the eye
