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

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.
