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 (111) 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 (330, 331, 332) insert for incorporation into an ophthalmic lens are also provided. In some embodiments, an ophthalmic lens (300) is cast molded from a silicone hydrogel and the lens includes at least one stacked functional layer insert portion.
