Astigmatism is an optical defect in which vision is blurred due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina. This may be due to an irregular or toric curvature of the cornea or lens. The two types of astigmatism are regular and irregular. Irregular astigmatism is often caused by a corneal scar or scattering in the crystalline lens, and cannot be corrected by standard spectacle lenses, but can be corrected by contact lenses. Although Astigmatism may occur in children and adults but doctors has named it as “disease”. It is fairly common and is not contagious. It is usually congenital - is present at birth - but can develop after an eye operation or an injury to the eye.
