Method and contact lens (3) for measuring a subject's three dimensional eye movement including torsional movement. A video camera (1) is provided for recording an image of the subject's eye (2). The contact lens (3) is provided for placement over the subject's eye (2). The contact lens (3) comprises one or more markers (3a,3b) that are detectable by the video camera (1) and are positioned at a lateral offset (D) with respect to a central part (3p) of the contact lens (3). The one or more markers (3a,3b) are configured for detecting torsional rotation (R) of the subject's eye (2) around a line of sight axis (C) of the subject's eye (2) by using the video camera (1) to track a position of the one or more markers (3a,3b).

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. By having rotational stability and translation, a contact lens having a progressive addition optic zone is provided.

A contact lens incorporating one or more compliant dynamic translation zones fabricated from a material that is readily deformable under eyelid pressure during blinking and which allows for the control over translation of the contact lens on the eye. The one or more compliant dynamic translation zones provide for the comfortable relative movement of the contact lens over the eye.

Disclosed herein is a contact lens comprising a rounded, minus-carrier, lenticular-like curve over a central, upper portion of the lens that allows the contact lens to translate upwards in downgaze.

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.

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.

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 class of prismatic contact lenses includes a first prism zone, having a first prism and a first optical power; and a progressive prism zone, adjacent to the first prism zone, having a progressive prism that varies from the first prism to a second prism. The prismatic contact lens can further comprise a second prism zone, adjacent to the progressive prism zone, having the second prism and a second optical power. Another class of prismatic contact lenses include a first prism zone, having a first prism and a first optical power; a second prism zone, adjacent to the first prism zone, having a second prism and a second optical power; and a sharp transition between the first prism zone and the second prism zone.

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.

A contact lens incorporating one or more surface modified zones on the anterior surface of the lens may be utilized to generate a friction driven rotational force when the upper and/or lower eyelids pass over the one or more regions during blinking. A small difference in the coefficient of friction between the modified and unmodified regions of the lens may result in an equivalent rotational force to that of a thickness gradient lens. This small difference in the coefficient of friction produces a means to orient and stabilize the contact lens on eye.
