1. A stacked functionalized media substrate for an ophthalmic lens, the substrate comprising:
- a first thin silicon layer shaped into a circular annulus;
a first adhesive film upon a first surface of the first thin silicon layer;
and a second thin silicon layer shaped into a circular annulus with an external radius smaller than that of the first layer.

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.
