Astigmatism correcting contact lenses

Abstract

The present disclosure is directed to contact lenses for the correcting a refractive error, particularly astigmatism, and other corneal irregularities. An exemplary lens comprises an inner portion, a peripheral portion, and a juncture therebetween. The inner portion provides optical correction for an eye. The peripheral portion conforms to a corneal surface of the eye. The juncture is a structurally flexible portion of the ophthalmic lens such that deformation of the peripheral portion in response to conforming to an astigmatism or higher order aberration of the corneal surface does not substantially deform the inner portion. When the lens is placed on the eye, the inner portion vaults over the corneal surface to form a lenticular volume. The optical correction is provided by a combination of the inner portion and the lenticular volume.
