This invention discloses methods and apparatus for providing an ophthalmic lens of variable optical power. The variable optic insert may have surfaces within that have differing radii of curvature. The variable optic insert may also comprise polarizing elements. In some examples, an intermediate optic piece may be formed to comprise a UV absorbing dye, allowing differential processing of regions on either side of the intermediate optic piece. In some embodiments, an ophthalmic lens is cast-molded from a silicone hydrogel. The various ophthalmic lens entities may include electroactive liquid crystal layers to electrically control refractive characteristics.本發明揭示用於提供具有可變光學倍率的眼用鏡片之方法及設備。可變光學插件可具有在其內曲率半徑不同的表面。可變光學插件亦可包含偏振元件。在一些實例中，可形成中間光學件以包含UV吸收染料，允許差別處理中間光學件之任一側的區域。在一些實施例中，眼用鏡片係由聚矽氧水凝膠鑄造模製。各種眼用鏡片實體可包括電活性液晶層以電控制折射特性。
