Abstract

This invention discloses methods and apparatus for providing an ophthalmic lens with media including an energy receptor. In some embodiments, the media includes an insert placed in a cavity formed to cast mold an ophthalmic lens from a reactive mixture.

Claims

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

depositing a conductive material capable of receiving energy via a radio wave on to a media;

depositing a reactive monomer mix into a first mold part;

positioning the media with the conductive material in contact with the reactive monomer mix;

positioning the first mold part proximate to a second mold part thereby forming a lens cavity with the media and conductive material and at least some of reactive monomer mix in the lens cavity; and

exposing the reactive monomer mix to actinic radiation.

2. The method of claim 1 wherein the conductive material capable of receiving energy via a radio wave is deposited on to the media via ink jetting.

3. The method of claim 2 wherein the media comprises a binder layer and the method additionally comprises the steps of:

depositing the binder layer onto one of the first mold part and the second mold part; and

ink jetting the conductive material onto the binder layer.

4. The method of claim 1 wherein the media is in contact with one or both of the first mold part and the second mold part.

5. The method of claim 2 wherein the conductive material is ink jetted in a pattern proximate to a circumference of the ophthalmic lens and outside of a field of vision when the ophthalmic lens is placed on an eye.

6. The method of claim 1 wherein an energy receptor comprising the conductive material capable of receiving energy via a radio wave comprises conductive fibers.

7. The method of claim 6 wherein the conductive fibers comprise carbon nanotubes.

8. The method of claim 7 wherein the conductive fibers comprise nanostructures.

9. The method of claim 7 wherein the binder layer comprises a pigment.

10. The method of claim 3 wherein the binder layer comprises a prepolymer.

11. The method of claim 3 wherein the binder layer comprises reactive monomer mix.
