Abstract

This invention discloses methods and apparatus for providing an ophthalmic lens with an energy source incorporated therein.

Claims

1. A method of forming an energized ophthalmic lens, the method comprising:

applying a binder layer to a first mold part;

placing a energy source onto the binder layer applied to the first mold part;

depositing a reactive mixture into the first mold part; and

polymerizing the reactive mixture to form an ophthalmic lens comprising polymerized lens material.

2. The method of claim 1 additionally comprising the steps of:

pre-polymerizing the binder layer.

3. The method of claim 1 wherein the binding layer comprises a polymer capable of forming an interpenetrating polymer network with the polymerized lens material.

4. The method of claim 1 wherein the energy source is attached to a flexible substrate and the flexible substrate is placed in physical communication with the binder layer.

5. The method of claim 1 additionally comprising the steps of defining an area comprising an optic zone and an area outside of the optic zone and placing the energy source the area outside of the optic zone.

6. The method of claim 1 wherein the binder layer comprises one or both of:

a homopolymer and a copolymer.

7. The method of claim 1 wherein the binder layer comprises a binding polymer comprising polymers and copolymers with functional groups that render the polymers and copolymers of the binding polymer capable of interactions with each other.

8. The method of claim 1 additionally comprising positioning one or more electrical current drawing components and the energy source comprises an attachment area connecting the energy source to one or more electrical current drawing components.

9. The method of claim 8 additionally comprising a reenergizing component.

10. The method of claim 9 wherein the reenergizing component comprises at least one of a photoelectric device, a radio frequency absorbing device, an inductive energy coupling device, a capacitive energy coupling device, a thermoelectric device or a piezeoelectric device.

11. The method of claim 10 wherein the reenergizing component directly provides energy to reenergize the energy device.

12. The device of claim 10 wherein the energizing component provides energy that is modified by an energy characteristic altering device to reenergize the energy device.

13. The device of claim 12 wherein an energizing device comprises a photoelectric device and includes an external light source.

14. The device of claim 1 wherein the energy source is a lithium ion battery.

15. The device of claim 14 wherein the battery is rechargeable.

16. The device of claim 14 wherein the battery is a single use battery.

17. The device of claim 1 wherein the energy source comprises at least one of;

fuel cells, capacitors, piezoelectrics or photoelectrics.

18. The device of claim 14 wherein the battery is encapsulated.

19. The device of claim 14 wherein the battery is shaped into a full annular shape.

20. The device of claim 14 wherein the battery is shaped into a partial annular shape.

21. The device of claim 14 wherein the battery is less than 500 microns thick.

22. The method of claim 1 wherein the energy source comprises a semiconductor material.

23. The method of claim 8 wherein the electrical current drawing components comprise constituents that have been printed.
