Abstract: Methods, devices, and systems for moving wet ophthalmic lenses are described in which the ophthalmic lenses are first placed in wells of lens carriers and are centered by the structure of the wells. The carriers are then moved to a transfer module of a packaging system for transferring the ophthalmic lenses in blister packages. The transfer from the carriers to the blister packages are performed by a pick and place robot having pickup heads sized and configured for suctioning the ophthalmic lenses from the lens carriers.

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.
