Patent number: 10802302Abstract: The invention provides for lenses fabricated as planar thin film coatings with continuous structure. The lensing action is due to optical axis orientation modulation in the plane of the lens. The lenses of the current invention are fabricated using photoalignment of a liquid crystal polymer wherein the polarization pattern of radiation used for photoalignment is obtained by propagating the light through an optical system comprising a shape-variant nonlinear spatial light polarization modulators.Type: GrantFiled: October 24, 2018Date of Patent: October 13, 2020Assignees: Beam Engineering for Advanced Measurements Co., The United States of America as Represented by the Secretary of the ArmyInventors: Nelson Tabirian, Svetlana Serak, Diane Steeves, Brian Kimball

Patent number: 9880398Abstract: This invention discloses methods and apparatus for providing a variable optic insert into an ophthalmic lens. The variable optic insert may have surfaces within that have differing radii of curvature. A liquid crystal layer may be used to provide a variable optic function and in some embodiments, an alignment layer for the liquid crystal layer may be patterned in a radially dependent manner. The patterning may allow for the index of refraction of the optic device to vary in a gradient-indexed or GRIN manner. An energy source is capable of powering the variable optic insert included within the ophthalmic lens. 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 optical characteristics.Type: GrantFiled: August 27, 2014Date of Patent: January 30, 2018Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Luciano De Sio, Frederick A.
