Acuvue Toric

Johnson and Johnson's Acuvue Toric contact lenses are 1-2 week disposable lenses designed for patients suffering from astigmatism.  Acuvue Toric lenses are made using the Dual Thin Zone to ensure that your lenses do not shift position while you are looking down.  Disposable lenses are replaced frequently to keep your eyes from becoming irritated because of deposit build up.  For ease of use, Acuvue Toric contacts are visibly tinted to assist you in locating your lenses in the solution.
