Abstract

A thin ophthalmic lens stabilized through incorporation of flange around all or a portion of a perimeter of the thin lens.

Claims (26)

1 . A stabilized ophthalmic thin lens comprising:

a thin lens having a perimeter; and

a flange extending from the perimeter.

2 . The stabilized thin lens of claim 1 wherein the thin lens has a thickness of 0.8 to 2.5 millimeters.

3 . The stabilized thin lens of claim 1 wherein the thin lens substrate comprises a dye.

4 . The stabilized thin lens of claim 1 wherein the thin lens comprises a functional film.

5 . The stabilized thin lens of claim 1 wherein the flange has a width of 5 to 15 millimeters.

6 . The stabilized thin lens of claim 1 wherein a thickness of the thin less is greater than a thickness of the flange.

7 . The stabilized thin lens of claim 1 wherein the flange is formed symmetrically about the thin lens.

8 . A stabilized ophthalmic thin lens comprising:

a round, unfinished thin lens; and

a round flange extending out ward from a perimeter of the thin lens.

9 . The stabilized thin lens of claim 8 wherein the thin lens has a thickness of 0.8 to 2.5 millimeters.

10 . The stabilized thin lens of claim 8 wherein a best fit plane formed through the thin lens is parallel to a plane defined by the flange.

11 . The stabilized thin lens of claim 8 wherein the thin lens comprises a functional film.

12 . The stabilized thin lens of claim 8 wherein the thin lens comprises a dye.

13 . The stabilized thin lens of claim 8 wherein a thickness of the thin lens is greater than a thickness of the flange.

14 . The stabilized thin lens of claim 8 wherein the flange is formed symmetrically about the thin lens.

15 . A method for stabilizing a thin lens comprising:

forming a thin lens having a perimeter; and

forming a flange extending from the perimeter.

16 . The method of claim 15 wherein the step of forming a thin lens having a perimeter comprises forming a thin lens by injection molding.

17 . The method of claim 15 wherein the step of forming a thin lens having a perimeter comprises forming a thin lens that has a thickness of 0.8 to 2.5 millimeters.

18 . The method of claim 15 wherein the step of forming a thin lens having a perimeter comprises forming a thin lens comprising a functional laminate.

19 . The method of claim 15 wherein the step of forming a flange extending from the perimeter comprises forming a flange having a thickness that is less than a thickness of the thin lens.

20 . The method of claim 15 wherein the step of forming a flange extending from the perimeter comprises forming a flange having a width of 5 to 15 millimeters.
