Astigmatism can be often corrected by glasses with a lens that has different radii of curvature in different planes (a cylindrical lens), contact lenses, or refractive surgery.

There are two distinct forms of astigmatism. So only a lens … The end result is the same. Toric lenses are very strong lenses that are kind of custom fit to smooth out corneal distortion. They are designed to focus the light better onto the retina. The lens is not simply accommodating for the refractive error, it’s forcing a shape onto the cornea.

In the past only rigid contact lenses (RGPs, also called GP lenses) were used; however, newer toric lenses usually feel more comfortable. Ophthalmic astigmatism is a refraction error of the eye in which there is a difference in degree of refraction in different meridians. Astigmatism is measured in diopters.

The first is a third-order aberration, which occurs for objects (or parts of objects) away from the optical axis.
