Abstract

A laminated contact lens according to the present invention includes at least a first contact lens and a second contact lens coupled to each other via the peripheral edge of each respective contact lens. The two contact lenses include a proximity zone depth and/or proximity zone width different from one another such that one or more chambers are formed between the two contact lenses. Various materials and/or components may be housed within the chamber to provide, among other things, vision correction tools, medicament administration, and/or cosmetic improvements to the user.

Claims

1. A laminated contact lens, comprising:

a first contact lens;

a second contact lens coupled to said first contact lens; and

a chamber formed between said first contact lens and said second contact lens.

2. The laminated contact lens of claim 1, wherein said first contact lens includes a first proximity zone depth (PZD) and said second contact lens includes a second PZD, wherein said first PZD and said second PZD are different proximity zone depths.

3. The laminated contact lens of claim 2, wherein said chamber is formed by a difference between said first PZD and said second PZD.

4. The laminated contact lens of claim 1, wherein said first contact lens is comprised of a hydrophilic monomer and said second contact lens is comprised of a hydrophilic monomer.

5. The laminated contact lens of claim 1, wherein said first contact lens is comprised of a hydrophobic monomer and said second contact lens is comprised of a hydrophobic monomer.

6. The laminated contact lens of claim 1, wherein said first contact lens is comprised of a hydrophobic monomer and said second contact lens is comprised of a hydrophilic monomer.

7. The laminated contact lens of claim 1, wherein the laminated contact lens includes a radius in the range of about 4.0 millimeters (mm) to about 8.0 mm.

8. The laminated contact lens of claim 1, further comprising:

a medicament housed within said chamber.

9. The laminated contact lens of claim 8, further comprising:

a bonding composition coupling said first contact lens to said second contact lens.

10. The laminated contact lens of claim 9, wherein said bonding composition is hydroxyethy methacrylate (HEMA).

11. The laminated contact lens of claim 10, wherein said HEMA is configured to transport said medicament at least one into and out of an eye of a user.

12. The laminated contact lens of claim 10, wherein said HEMA is configured to transport said medicament at least one into and out of an eye of a user at a pre-determined rate.

13. The laminated contact lens of claim 8, further comprising:

at least one hole in at least one of said first contact lens and said second contact lens such that said medicament is transported at least one of into and out of an eye of a user.

14. The laminated contact lens of claim 8, further comprising:

at least one hole in at least one of said first contact lens and said second contact lens such that said medicament is transported at least one of into and out of an eye of a user at a pre-determined rate.

15. The laminated contact lens of claim 8, further comprising:

a gap formed between a peripheral landing formed by a first periphery of said first contact lens and a second peripheral of said second contact lens such that said medicament is transported at least one of into and out of an eye of a user.

16. The laminated contact lens of claim 8, further comprising:

a gap formed between a peripheral landing formed by a first periphery of said first contact lens and a second peripheral of said second contact lens such that said medicament is transported at least one of into and out of an eye of a user at a pre-determined rate.

17. The laminated contact lens of claim 1, further comprising:

at least one of a gas, a liquid, and a solid housed within said chamber to improve the vision of a user.

18. The laminated contact lens of claim 1, further comprising:

a color component housed within said chamber to give the appearance that an eye of a user has a particular color.

19. The laminated contact lens of claim 1, further comprising:

at least one nano-scale mechanical system and at least one photocell housed in said chamber.

20. The laminated contact lens of claim 19, wherein said nano-scale mechanical system comprises:

communication media configured to display at least one of images and messages to a user.

21. The laminated contact lens of claim 1, wherein the lens has an invaginated edge.

22. The laminated contact lens of claim 1, wherein the lens has a semi-rounded edge.

23. A laminated contact lens, comprising:

a first contact lens;

a second contact lens coupled to said first contact lens;

a first chamber formed between said first contact lens and said second contact lens; and

a second chamber formed between said first contact lens and said second contact lens.

24. The laminated contact lens of claim 23, wherein said first contact lens includes a first proximity zone depth (PZD) and said second contact lens includes a second PZD, wherein said first PZD and said second PZD are different proximity zone depths.

25. The laminated contact lens of claim 24, wherein said first chamber and said second chamber are formed by a difference between said first PZD and said second PZD.

26. The laminated contact lens of claim 23, wherein:

said first contact lens includes a first exterior edge and a first interior edge; and

said second contact lens includes a second exterior edge and a second interior edge.

27. The laminated contact lens of claim 26, wherein:

at least one said first exterior edge, said first interior edge, said second exterior edge, and said second interior edge includes a sigmoidal shape, with the remaining edges including a curved shape.

28. The laminated contact lens of claim 26, wherein:

each of said first exterior edge, said first interior edge, said second exterior edge, and said second interior edge includes a sigmoidal shape.

29. The laminated contact lens of claim 26, wherein:

each of said first exterior edge, said first interior edge, said second exterior edge, and said second interior edge includes a curved shape.
