Abstract

This invention discloses a media substrate for incorporation into ophthalmic lenses that has been formed by the stacking of multiple functionalized layers. Additionally, methods and apparatus for providing a stacked functional layer insert for incorporation into an ophthalmic lens are also provided. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel and the lens includes at least one stacked functional layer insert portion.

Claims

1. A media substrate for an ophthalmic lens, the media substrate comprising:

a plurality of functionalized silicon layers; and

an adhesive film placed between at least a portion of two of the functionalized silicon layers thereby forming a stacked feature,

wherein each of the functionalized silicon layers are in the shape of an annulus and each individually has a function of at least one of energizing, activating or controlling an ophthalmic lens, and

wherein one of the functionalized silicon layers has an external radius smaller than that of another one of the functionalized silicon layers.

2. The media substrate of claim 1 wherein:

one of the functionalized silicon layers comprises a semiconductor substrate with electronic circuitry in proximity to its surface.

3. The media substrate of claim 1 wherein:

one of the functionalized silicon layers comprises a substrate with layers comprising an electrochemical energizing component.

4. The media substrate of claim 1 wherein:

the media substrate is encapsulated in a polysilicone based polymer.

10. The media substrate of claim 1, wherein:

the functionalized silicon layers are stacked to have a three dimensional shape comprising a general profile of the ophthalmic lens.

5. An ophthalmic lens comprising:

a plurality of functionalized silicon layers;

an adhesive film placed between at least a portion of two of the functionalized silicon layers thereby forming a stacked feature; and

a polymeric lens form in which the stacked feature is embedded,

wherein each of the functionalized silicon layers are in the shape of an annulus and each individually has a function of at least one of energizing, activating or controlling the ophthalmic lens, and

wherein one of the functionalized silicon layers has an external radius smaller than that of another one of the functionalized silicon layers.

6. The ophthalmic lens of claim 5 wherein:

one of the functionalized silicon layers comprises one or more electrochemical cells.

7. The ophthalmic lens of claim 6 wherein:

one of the functionalized silicon layers comprises semiconductor electronic circuitry capable of controlling electric current flow from the electrochemical cells.

8. The ophthalmic lens of claim 7 additionally comprising:

an electroactive lens component, wherein the semiconductor electronic circuitry is electrically connected to the electroactive lens component.

9. The ophthalmic lens of claim 8 additionally comprising:

a metallic layer capable of functioning as an antenna.

11. The ophthalmic lens of claim 5, wherein:

the functionalized silicon layers are stacked to have a three dimensional shape comprising a general profile of the ophthalmic lens.
