METHOD FOR FORMING A MEDIA SUBSTRATE FOR AN OPHTHALMIC LENS AND MEDIA SUBSTRATE FOR AN OPHTHALMIC LENS

摘要

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.
