Abstract: A lens for refractive tear shaping, having a curved lens body with a peripheral edge and a central opening therein. The central opening is shaped and sized and has a tear shaping edge structured to form a tear meniscus within the central opening. The tear meniscus being formed by interaction of a tear film of the eye and the tear shaping edge and having a posterior curvature conforming to an anterior corneal curvature and an anterior curvature. The anterior curvature is dependent on the size and shape of the central opening and structure of the tear shaping edge.

Abstract: A conjunctival cover including an annular generally curved shell having a conjunctival portion structured to conform to and overly at least part of the conjunctiva of an eye. The annular generally partially spherical shell defines a generally central opening. The central opening is sized to leave a cornea of the eye substantially or partially uncovered when the conjunctival cover is applied to the eye.

Abstract: A contact lens for application in practice of orthokeratology on an eye, including a curved shell having a concave surface and a convex surface. The concave surface includes a carrier zone and a back shaping zone, the back shaping zone having a first curvature and the carrier zone having at least one second curvature. The curved shell has a geometric center and the back shaping zone has a shaping zone center and the back shaping zone center is offset peripherally from the geometric center. The curved shell can have an overall diameter that approximates a corneal limbal diameter of the eye to which the contact lens is to be applied.

Abstract: A contact lens, including a central portion formed from a flexible or soft oxygen permeable material and a peripheral portion formed from a substantially rigid material. The central portion and the peripheral portion are coupled to each other at a coupling portion.

Abstract: A contact lens system, including a peripheral conjunctival cover portion including a shell curved and sized to substantially overly a conjunctiva of an eye. The conjunctival cover portion defines a full thickness central opening therethrough. The central opening is positioned within the conjunctival cover and sized to expose at least a portion of a cornea of the eye. The contact lens system further includes a central contact lens portion that is substantially equivalent in size to the central opening and positioned or positionable at the central opening.
