Abstract: A flexible optical element adopting liquid crystals (LCs) as the materials for realizing electrically tunable optics is foldable. A method for manufacturing the flexible element includes patterned photo-polymerization. The LC optics can include a pair of LC layers with orthogonally aligned LC directors for polarizer-free properties, flexible polymeric alignment layers, flexible substrates, and a module for controlling the electric field. The lens power of the LC optics can be changed by controlling the distribution of electric field across the optical zone.

Abstract: Contact lenses having even surface coatings are manufactured by coating a polyvinyl alcohol polymer on a lens-forming surface of a contact lens mold, applying a contact lens coating composition onto the polyvinyl alcohol polymer, and curing a contact lens formulation in the coated contact lens mold. During curing, the coating composition transfers from the mold to the contact lens surface. The polyvinyl alcohol helps prevent the contact lens coating composition from being solubilized by the contact lens composition during the curing step.

Abstract: Apparatus and methods are described for manufacturing contact lenses by forming a contact lens mold half, and removing the mold half. The mold half can then be combined with a complementary mold half and used to cast-mold a contact lens. The apparatus includes first and second plates each carrying tool halves. The plates reciprocate between an open, spaced apart configuration, and a closed configuration in which they hold complementary tool halves in contact with one another. When the plates are opened after forming a mold half, a gripper plate removes the mold half from the first plate or the second plate.
