Can Astigmatism Be Corrected With Contact Lenses?
Several years ago those inflicted with astigmatism had to rely on eye glasses for their vision correction. Today that limitation is merely a memory of the past thanks to several advancements in contact lens technology. Since astigmatism is the result of an irregular shaped lens or cornea, a contact lens must designed to fit the atypical shape of the eye closely and comfortably in order to provide clear, crisp vision. A contact lens that is designed to fit an irregular shape and correct astigmatism is called a toric lens. The unique curvature of eyes with astigmatism require that contacts meet the wearer’s specific vision correction needs since a slight variation can result in an ill-fitting lens. The difference between a toric lens and a spherical one is that the toric has two different powers – one power corrects the astigmatism while the other corrects the nearsightedness or farsightedness. While toric lenses are very similar to spherical contacts the addition of the second power mak
