Abstract

This invention discloses methods and apparatus for providing an ophthalmic lens with a stacked integrated component device for function. In some embodiments, the stacked integrated component device may contain an energy source capable of powering an electrical component incorporated into the lens.

First claim

What is claimed is:

1. An energized ophthalmic lens device comprising:
a lens with an optical zone and a non-optical zone comprising a silicon hydrogel material;
an energy source embedded in the silicon hydrogel material in an area of the lens comprising the non-optical zone, wherein the energy source comprises a fuel cell;
a stacked integrated component device at least partially embedded within the silicon hydrogel material in an area of the lens comprising the non-optical zone, the stacked integrated component device including one or more substrate layers stacked together into a single unit;
one or more electrical current drawing components mounted to the one or more substrate layers of the stacked integrated component device; and
an attachment area connecting the fuel cell to the one or more electrical current drawing components.

2. The device of claim 1 wherein the current drawing component is embedded in the non-optical zone.

3. The device of claim 1 wherein the fuel cell uses biologically available materials in the ophthalmic environment as a fuel source.

4. The device of claim 1 wherein the fuel cell uses a fuel source located within the energized ophthalmic lens device.
