Embodiment Construction

[0019] The present disclosure will now be described more fully hereinafter with reference to specific exemplary embodiments. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0020] Disclosed herein is a contact lens comprising a lens in an upper portion (top) of the lens. For example, the lens may include a circular, loaded, lenticular curvature over the central upper portion of the lens, although other lens shapes, designs, and locations are contemplated.

[0021] Various embodiments of the contact lenses disclosed herein include an overlying lens design that produces: (1) rotational stabilization of the contact lens in all fixations, (2) upward translation of the contact lens when the eye is in a downward gaze or movement, and (3) generally centering the contact lens over the cornea and pupil as needed as the person's line of sight changes. "Upward translation of the contact lens wh...

Abstract

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 withan 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 atop 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit of U.S. Patent Application Serial No. 15 / 274,159, filed September 23, 2016, which claims the benefit of U.S. Provisional Application No. 62 / 222,376, filed September 23, 2015, The above patent application is incorporated herein by reference in its entirety. Background technique [0003] Current state of the art rotational stabilization includes back surface torics (effective for rigid gas permeable contact lenses), base down and peripheral ballasted prisms, or dynamic stabilization (as a modification to base down prisms). For some patients one or none of the existing designs are sufficient to provide rotational stabilization for contact lenses. [0004] Rigid gas permeable (RGP) contact lenses have traditionally been fitted with a "lid-attached" fit either by using the naturally thicker rim of a negative RGP contact lens or by adding a carrier lens (thicker rim) to a positi...
