Abstract

Claims (31)

1. An ophthalmic element comprising:

a polymeric ophthalmic lens having a concave surface and a convex surface, and a laminate bonded to the polymeric ophthalmic lens, the ophthalmic element comprising, in the following order from a forward face of the element:

a) an a bigradient interference layer having segments separated by a gap in the interference material between the segments of the bigradient interference layer,

b) an organic polymeric hard coat layer extending across the gap in the interference material,

c) a polymeric lens segment, and

d) a polarizing layer.

2. The ophthalmic element of claim 1 wherein said polymeric lens segment comprises a polycarbonate resin.

3. The ophthalmic element of claim 1 wherein the polymeric ophthalmic lens comprises an injection molded, polymeric ophthalmic lens having a concave surface and a convex surface.

4. The ophthalmic element of claim 1 wherein the lens comprises two lens segments that have been bonded together.

5. The ophthalmic element of claim 2 wherein the lens comprises two lens segments that have been bonded together.

6. The ophthalmic element of claim 3 wherein the lens comprises two lens segments that have been bonded together.

7. The ophthalmic element of claim 4 wherein the polarizing layer is between the two lens segments.

8. The ophthalmic element of claim 5 wherein the polarizing layer is between the two lens segments.

9. The ophthalmic element of claim 6 wherein the polarizing layer is between the two lens segments.

10. The ophthalmic element of claim 4 wherein the polarizing layer comprises a polarizing laminate that is positioned between the two lens segments.

11. The ophthalmic element of claim 5 wherein the polarizing layer comprises a polarizing laminate that is positioned between the two lens segments.

12. The ophthalmic element of claim 6 wherein the polarizing layer comprises a polarizing laminate that is positioned between the two lens segments.

13. The ophthalmic elements of claim 1 wherein the hardcoat comprises a layer comprising units selected from the group consisting of acrylates, siloxanes, and epoxy resin units.

14. The ophthalmic element of claim 4 wherein the hardcoat comprises a layer comprising units selected from the group consisting of acrylates, siloxanes, and epoxy resin units.

15. The ophthalmic element of claim 8 wherein the hardcoat comprises a layer comprising units selected from the group consisting of acrylates, siloxanes, and epoxy resin units.

16. The ophthalmic element of claim 10 wherein the hardcoat comprises a layer comprising units selected from the group consisting of acrylates, siloxanes, and epoxy resin units.

17. The ophthalmic element of claim 1 wherein the interference layer has an image therein caused by variation in the thickness of the interference layer.

18. The ophthalmic element of claim 17 wherein the variation in thickness includes a complete absence of interference layer material in the form of an image.

19. The ophthalmic element of claim 18 wherein the image is in the form of a logo.

20. An ophthalmic element comprising:

a polymeric ophthalmic lens having a concave surface and a convex surface, and a laminate bonded to the polymeric ophthalmic lens, the ophthalmic element comprising, in the following order from a forward face of the element:

a) an a bigradient interference layer having segments separated by a gap in the interference material between the segments of the bigradient interference layer,

b) an organic polymeric hard coat layer extending across the gap in the interference material, the organic polymeric hard coat layer comprising units selected from the group consisting of acrylates, siloxanes, and epoxy resin units,

e) a polymeric lens segment, and

f) a polarizing layer.

21. The ophthalmic element of claim 20 wherein the image is in the form of a logo.
