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 contact lens comprising a superior lenticular aspect located in a central, upper portion of the lens, wherein the superior lenticular aspect of the lens is shaped to interact with an upper tarsal plate of an upper eyelid of a wearer such that the contact lens translates upward in a downgaze of the wearer to place a viewing zone of the contact lens over a pupil or cornea of the wearer and the superior lenticular aspect provides rotational stabilization to the contact lens,
wherein:
a distance from an outer edge of the contact lens to the superior lenticular aspect is from 0.1 mm to 5.0 mm.

2. A contact lens comprising a superior lenticular aspect located in a central, upper portion of the lens, wherein the superior lenticular aspect of the lens is shaped to interact with an upper tarsal plate of an upper eyelid of a wearer such that the contact lens translates upward in a downgaze of the wearer to place a viewing zone of the contact lens over a pupil or cornea of the wearer and the superior lenticular aspect provides rotational stabilization to the contact lens,
wherein:
a distance from an outer edge of the contact lens to the superior lenticular aspect is from 0.1 mm to 5.0 mm; and
the superior lenticular aspect comprises from 5% to 75% of an area from the outer edge of the contact lens to a geometric center of the contact lens.

3. A contact lens comprising a superior lenticular aspect located in a central, upper portion of the lens, wherein the superior lenticular aspect of the lens is shaped to interact with an upper tarsal plate of an upper eyelid of a wearer such that the contact lens translates upward in a downgaze of the wearer to place a viewing zone of the contact lens over a pupil or cornea of the wearer and the superior lenticular aspect provides rotational stabilization to the contact lens,
wherein:
a distance from an outer edge of the contact lens to the superior lenticular aspect is from 0.1 mm to 5.0 mm; and
the superior lenticular aspect comprises from 5% to 75% of an area from the outer edge of the contact lens to a geometric center of the contact lens; and
a thickness of the superior lenticular aspect is from 1.5 to 10 times thicker than a maximum thickness of a remainder of the contact lens.

4. The contact lens of claim 3 , wherein the thickness of the superior lenticular aspect is 1.5 times thicker than the maximum thickness of the remainder of the contact lens.

5. The contact lens of claim 3 , wherein the thickness of the superior lenticular aspect is 2 times thicker than the maximum thickness of the remainder of the contact lens.

6. The contact lens of claim 3 , wherein the thickness of the superior lenticular aspect is 3 times thicker than the maximum thickness of the remainder of the contact lens.

7. The contact lens of claim 3 , wherein the thickness of the superior lenticular aspect is 4 times thicker than the maximum thickness of the remainder of the contact lens.

8. The contact lens of claim 3 , wherein the superior lenticular aspect comprises from 10% to 70% of an area from the outer edge of the contact lens to the geometric center of the contact lens.

9. The contact lens of claim 3 , wherein the superior lenticular aspect comprises from 15% to 65% of the area from the outer edge of the contact lens to the geometric center of the contact lens.

10. The contact lens of claim 3 , wherein the superior lenticular aspect comprises from 20% to 60% of the area from the outer edge of the contact lens to the geometric center of the contact lens.

11. The contact lens of claim 3 , wherein the superior lenticular aspect comprises from 25% to 55% of the area from the outer edge of the contact lens to the geometric center of the contact lens.

12. The contact lens of claim 3 , wherein the superior lenticular aspect comprises from 25% to 55% of the area from the outer edge of the contact lens to the geometric center of the contact lens.

13. The contact lens of claim 3 , wherein the superior lenticular aspect comprises from 5% to 25% of the area from the outer edge of the contact lens to the geometric center of the contact lens.

14. The contact lens of claim 3 , wherein the superior lenticular aspect comprises from 10% to 20% of the area from the outer edge of the contact lens to the geometric center of the contact lens.

15. The contact lens of claim 3 , wherein the distance from the outer edge of the contact lens to the superior lenticular aspect is from 0.1 mm to 0.5 mm.

16. The contact lens of claim 3 , wherein the distance from the outer edge of the contact lens to the superior lenticular aspect is from 0.5 mm to 1.0 mm.

17. The contact lens of claim 3 , wherein the distance from the outer edge of the contact lens to the superior lenticular aspect is from 1.0 mm to 1.5 mm.

18. The contact lens of claim 3 , wherein the distance from the outer edge of the contact lens to the superior lenticular aspect is from 0.5 mm to 1.5 mm.

19. The contact lens of claim 3 , wherein the distance from the outer edge of the contact lens to the superior lenticular aspect is from 1.5 mm to 2.0 mm.

20. The contact lens of claim 3 , wherein the contact lens further comprises a prism.
