Disclosed herein is a contact lens comprising a lenticular in a superior portion of the contact lens wherein the contact lens attaches to an upper eyelid of a wearer by the lenticular interacting with an upper tarsal plate of the upper eyelid of a wearer, said interaction allows the contact lens to translate upwards in downgaze and maintain rotational stability. In one aspect, the lenticular has a top surface, said top surface having a shape selected from the group consisting of flat, flat with rounded corners, concave, convex or tapered having a thicker portion closer to an edge of the contact lens, or combinations thereof. In another aspect, the lenticular is comprised of a plurality of lenticular sections. In yet another aspect, the lenticular is anatomically-shaped.

Operation of an electronic contact lens takes into account saccadic motion of the eye and reduced visual perception during saccades (saccadic suppression). The user's eye motion is tracked, and onset of a saccade is detected based on the eye's motion. For example, saccades may be detected when the eye's acceleration or jerk exceeds a threshold. The endpoint of the saccade is then predicted in real-time while the saccade is still occurring. This may be the temporal endpoint (i.e., when the saccade ends) and/or the positional endpoint (i.e., the eye position at the end of the saccade). Operation of the electronic contact lens is adjusted based on the predicted endpoint.

A system of contact lenses includes at least two contact lenses, each lens having a visual correction for a non-rotationally symmetric eye aberration. Each lens has a different level or degree of a stabilization that is characterized by a thickness differential between a thickness of a stabilization zone and a thickness of a non-stabilization zone.

Disclosed herein is a contact lens. Some disclosed embodiments comprise a lenticular aspect. In some instances the lenticular aspect varies in at least one of thickness, distance from the edge of the contact lens, or lenticular height along its length. In one aspect, a superior portion of the lenticular aspect attaches to an upper eyelid of a wearer by at least a portion of the lenticular aspect interacting with an upper tarsal plate of the upper eyelid of a wearer.

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.

Ophthalmic lenses are described herein. An example ophthalmic lens may comprise a first surface. The example ophthalmic lens may comprise a second surface disposed opposite the first surface and defining a volume of lens material therebetween. A thickness profile of the volume of lens material may be derived from one or more eyelid profiles such that a thickness gradient of the volume of lens material is oriented to be substantially orthogonal to a target eyelid margin shape.

Disclosed herein is a soft contact lens comprising a lenticular in a superior portion of the contact lens wherein the contact lens attaches to an upper eyelid of a wearer by the lenticular interacting with an upper tarsal plate of the upper eyelid of a wearer, wherein the contact lens is configured to provide one or more of an enhanced tear exchange, a greater tear layer thickness, or increased oxygen uptake of a cornea of a wearer.

A soft contact lens that includes a dome-shaped flexible sheet of material. The dome-shaped flexible sheet of material includes: (a) a non-optic zone comprising the periphery of the dome-shaped flexible sheet of material, and including: an upper peripheral zone comprising an upper part of the periphery of the dome-shaped flexible sheet of material, and a lower peripheral zone comprising a lower part of the periphery of the dome-shaped flexible sheet of material. The curvature of the dome-shaped flexible sheet of material is dynamically adaptable, by virtue of at least one of the upper and lower peripheral zones being structured to laterally expand and contract; and (b) an optic zone disposed in an area of the dome-shaped flexible sheet of material that lies between the upper and lower peripheral zones, wherein the optic zone is configured to align with a visual axis of the eye.

There is provided a contact lens having a convex front surface and a concave rear surface, the front surface being divided into an optical portion, an edge joining the front and rear surfaces, a first smoothing portion arranged on an outer periphery of the optical portion, a peripheral portion arranged on an outer periphery of the first smoothing portion, and a second smoothing portion connecting the peripheral portion and the edge, the front surface having mirror image symmetry with respect to a vertical meridian as a boundary extending from an upper end of the lens to a lower end of the lens passing through a midpoint of the lens, and having mirror image symmetry also with respect to the horizontal meridian perpendicular to the vertical meridian at the lens midpoint, the peripheral portion being arranged to include the horizontal meridian, and configured of: a first peripheral portion arranged to include the horizontal meridian and having a shape so as to maximize a thickness of the contact lens on the horizontal meridian, a second peripheral portion arranged to include the vertical meridian and having a shape so as to minimize the thickness of the contact lens on the vertical meridian, a first peripheral auxiliary portion which is a portion adjacent to the first peripheral portion, having a surface shape so as to keep the thickness of the contact lens constant; and an inclined portion which is a portion connecting the first peripheral auxiliary portion and the second peripheral portion to form a continuous surface, and having a surface shape that changes the thickness of the contact lens.
