Abstract

This invention discloses methods and apparatus for providing a media insert with a Data Processor into an ophthalmic lens. An energy source is capable of powering the Data Processor included within the ophthalmic lens. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel.

First claim

The invention claimed is:

1. A method of forming a contact lens, the method comprising the steps of:
forming a media insert by attaching a data processor, a battery and a liquid meniscus lens to a substrate;
positioning the media insert within a portion of a contact lens mold;
depositing a reactive monomer mix into the contact lens mold and encapsulating the media insert therein; and
exposing the reactive monomer mix to actinic radiation or heat to form the contact lens.

2. The method of forming a contact lens of claim 1 , wherein the step of forming the media insert further comprises attaching an energy harvester to the substrate.

3. The method of forming a contact lens of claim 2 , wherein the energy harvester comprises a photoreceptor.

4. The method of forming a contact lens of claim 1 , wherein the step of forming the media insert further comprises forming a conductive circuit path on the substrate between the data processor and the battery.

5. The method of claim 1 , wherein the step of forming the media insert further comprises attaching a focus adjustment activator selected from the group consisting of a magnetically activated switch, a photo-optically activated switch, and an electrical sensor configured to sense a signal within an eye to the substrate in communication with said data processor.

6. The method of claim 1 , wherein said substrate is flexible.
