Abstract
This invention discloses methods and apparatus for providing a media insert with an energy source to an ophthalmic lens. The energy source is capable of powering a component included within the ophthalmic lens. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel and the component includes an electro-optical lens portion.
Claims6
A method of forming an ophthalmic lens comprising:
- forming a media insert by mounting an energy source and at least one current drawing component on a substrate;
- placing the media insert proximate to a first mold part such that the media insert is positioned in a non-optical zone of the ophthalmic lens;
- depositing a reactive monomer mix into the first mold part and encapsulating the media insert therein;
- positioning a second mold part proximate the first mold part to create an ophthalmic lens shaped cavity filled with the reactive monomer mix;
- and
- exposing the reactive monomer mix to actinic radiation or heat to form an ophthalmic lens comprising the media insert.
