METHOD AND APPARATUS FOR OPHTHALMIC DEVICES INCLUDING GRADIENTLY-ORDERED SHAPED LIQUID CRYSTAL LAYERS AND DIELECTRIC LAYERS Russian patent published in 2016 - IPC G02C7/08 G02C7/04 

FIELD: optics.

SUBSTANCE: declared group of inventions describes methods and apparatus for providing an ophthalmic lens with a variable optic insert. Ophthalmic lens device with a variable optic insert comprises a front curve surface and back curve surface and at least a portion within the optical zone of the ophthalmic lens device. Besides, front surface and back surface are configured to form at least a part of one chamber. At least the first layer of dielectric material, thickness of which may vary at least within the optical zone of the device, can promote formation of an electric field through the liquid crystal layer. Power source is configured to supply insert with variable optical properties included in the ophthalmic lens. In some embodiments ophthalmic lenses are cast from silicone-hydrogel. Different elements of the ophthalmic lens can include a liquid crystal layers to electrically control optical characteristics.

EFFECT: possibility of changing the lens to provide accommodation of vision.
