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 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.

First claim

What is claimed is:

1. A contact lens comprising:
a front surface; and
a back surface, wherein the back surface is proximate an eye of a wearer when in place on the eye of the wearer;
wherein the contact lens has a first thickness in a superior portion of the contact lens that is greater than a second thickness at a central portion of the contact lens, said thickness defined by an axial distance between the front surface and the back surface;
wherein the first thickness interacts with an upper tarsal plate of an upper eyelid of the wearer and said first thickness is configured to attach the contact lens to the upper eyelid, said attachment translating the contact lens upwards in a downgaze of the wearer, and
wherein the first thickness 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.

2. The contact lens of claim 1 , wherein the contact lens is one of a soft contact lens, a rigid gas permeable contact lens, or a hybrid contact lens.

3. The contact lens of claim 1 , wherein the first thickness interacting with the upper tarsal plate of the upper eyelid of the wearer provides centration and rotational stability to the contact lens.

4. The contact lens of claim 1 , wherein the first thickness is comprised of a plurality of sections, each section have a thickness that is thicker than the second thickness at the central portion of the contact lens.

5. The contact lens of claim 1 , wherein the first thickness is anatomically-shaped.

6. The contact lens of claim 5 , wherein the anatomical shape of the first thickness is designed to fit within Kessing's Space of the wearer's upper eyelid.

7. A contact lens comprising:
a front surface; and
a back surface, wherein the back surface is proximate an eye of a wearer when in place on the eye of the wearer;
wherein the contact lens has a first thickness in a superior portion of the contact lens that is greater than a second thickness at a central portion of the contact lens, said thickness defined by an axial distance between the front surface and the back surface;
wherein the first thickness interacts with an upper tarsal plate of an upper eyelid of the wearer and said first thickness is configured to attach the contact lens to the upper eyelid, said attachment translating the contact lens upwards in a downgaze of the wearer, and
wherein the second thickness is comprised of a plurality of sections, each section thicker than the second thickness at the central portion of the contact lens.

8. The contact lens of claim 7 , wherein the contact lens is a soft contact lens, a rigid gas permeable contact lens, or a hybrid contact lens.

9. The contact lens of claim 7 , wherein the first thickness interacting with the upper tarsal plate of the upper eyelid of a wearer provides centration and rotational stability of the contact lens.

10. The contact lens of claim 7 , wherein at least one of the plurality of sections is anatomically-shaped.

11. The contact lens of claim 10 , wherein the anatomical shape of the at least one section of the plurality of sections is designed to fit within Kessing's Space of the wearer's upper eyelid.

12. The contact lens of claim 7 , wherein each section of the plurality of sections has a shape selected from the group consisting of arced, curved, round, circular, hemispherical, square, rectangular, triangular, oval, multi-sided, and combinations thereof.

13. The contact lens of claim 7 , wherein each section of the plurality of sections has a top surface, said top surface having a shape selected from the group consisting of curved, round, spherical, flat, flat with rounded corners, concave, convex or tapered having a thicker portion closer to an edge of the contact lens, or combinations thereof.

14. A contact lens comprising:
a front surface; and
a back surface, wherein the back surface is proximate an eye of a wearer when the contact lens is in place on the eye of the wearer;
wherein the contact lens has a first thickness in a superior portion of the contact lens that is greater than a second thickness at a central portion of the contact lens, said thickness defined by an axial distance between the front surface and the back surface;
wherein the first thickness interacts with an upper tarsal plate of an upper eyelid of the wearer and said first thickness is configured to attach the contact lens to the upper eyelid, said attachment translating the contact lens upwards in a downgaze of the wearer, and
wherein the first thickness has an anatomical shape.

15. The contact lens of claim 14 , wherein the contact lens is a soft contact lens, a rigid gas permeable contact lens, or a hybrid contact lens.

16. The contact lens of claim 14 , wherein the first thickness interacting with the upper tarsal plate of the upper eyelid of a wearer provides centration and rotational stability.

17. The contact lens of claim 14 , wherein the first thickness is comprised of a plurality of sections located in the superior portion of the contact lens, each section of the plurality of sections thicker than the second thickness at the central portion of the contact lens.

18. The contact lens of claim 14 , wherein the anatomical shape of the first thickness is designed to fit within Kessing's Space of the wearer's upper eyelid.
