  • 3 types of Astigmatism

    Posted on September 10 2014


    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. The more common regular astigmatism arising from either the cornea or crystalline lens can be corrected by eyeglasses or toric lenses. A ‘toric’ surface resembles a section of the surface of a Rugby ball or a doughnut where there are two regular radii, one smaller than the other one. This optical shape gives rise to astigmatism in the eye.
