Abstract

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.

First claim

What is claimed is:

1. A rotationally stable contact lens comprising:
an eye-facing side and a side that faces away from the eye; and
wherein the contact lens has a first thickness in a superior portion of the contact lens that is greater than a second thickness at any other portion of the contact lens, said first and second thicknesses defined by an axial distance between the eye-facing side and the side that faces away from the eye;
wherein the first thickness is shaped to interact with an upper tarsal plate of an upper eyelid of a wearer and said first thickness is configured to attach the contact lens to the upper eyelid providing rotational stabilization to the contact lens.

2. The rotationally stable contact lens of claim 1 , wherein the contact lens comprises a soft contact lens.

3. The rotationally stable contact lens of claim 1 , wherein the contact lens comprises a rigid gas permeable contact lens.

4. The rotationally stable contact lens of claim 1 , wherein the contact lens comprises a hybrid contact lens.

5. The rotationally stable contact lens of claim 1 , wherein the attachment of the contact lens to the upper eyelid provides centration to the contact lens.

6. The rotationally stable contact lens of claim 1 , wherein the first thickness comprises a rounded, minus-carrier, lenticular curve.

7. The rotationally stable contact lens of claim 1 , wherein the contact lens comprises a multi-focal contact lens.

8. The rotationally stable contact lens of claim 1 , wherein the attachment of the contact lens to the upper eyelid causes the contact lens to translate upward in a downgaze of the wearer to place a viewing zone of the contact lens over a pupil or cornea of the wearer.

9. The rotationally stable contact lens of claim 8 , wherein the viewing zone of the contact lens is one of a plurality of viewing zones comprising at least a distance viewing zone and a near viewing zone.

10. The rotationally-stable contact lens of claim 9 , wherein at least one of the distance viewing zone and the near viewing zone remains above a lower eyelid margin of the wearer when the eye is open.

11. The rotationally stable contact lens of claim 1 , wherein the central portion of the contact lens further comprises a liquid crystal material, a photochromic material, a sensor, or a filter.

12. The rotationally stable contact lens of claim 11 , wherein the photochromic material is used to display an image on the contact lens.

13. The rotationally stable contact lens of claim 11 , wherein the liquid crystal material is used to display an image on the contact lens.

14. The rotationally stable contact lens of claim 13 , wherein the image comprises an electronically-generated and/or other virtual optically-displayed image.

15. The rotationally stable contact lens of claim 1 , wherein the contact lens further comprises a base down prism.

16. The rotationally stable contact lens of claim 15 , wherein the base down prism provides a change in power from a central optic zone of the contact lens.

17. The rotationally stable contact lens of claim 15 , wherein the base down prism is located in an inferior portion of the lens portion.

18. The rotationally stable contact lens of claim 17 , wherein the base down prism comprises a base having a thickness greater than a top of the prism.

19. The rotationally stable contact lens of claim 18 , wherein an edge of an upper eyelid of the wearer squeezes the thicker base of the prism downwards with each blink.

20. The rotationally stable contact lens of claim 18 , wherein the base of the prism is configured such that it interacts with a lower eyelid with each blink of the wearer, so that the base of the prism remains above a lower eyelid margin.
