  • Patent number: 11320674
    Abstract: An apparatus to treat refractive error of an eye comprises an electroactive component configured to switch between a light scattering or optical power providing configuration to treat refractive error of the eye and a substantially transparent configuration to allow normal viewing. The electroactive component can be located on the lens away from a central axis of the lens to provide light to a peripheral region of the retina to decrease the progression of myopia. The electroactive component can be located on the lens away from the central axis of the lens in order for the wearer to view objects through an optical zone while the electroactive component scatters light. The electroactive component can be configured to switch to the substantially transparent configuration to allow light to pass through the electroactive component and to allow the lens to refract light to correct vision and allow normal viewing through the lens.

  • Patent number: 11305515
    Abstract: A system and method are provided for forming body structures including energy filters/shutter components, including energy/light directing/scattering layers that are actively electrically switchable. The filters or components are operable between at least a first mode in which the layers, and thus the presentation of the shutter components, appear substantially transparent when viewed from an energy/light incident side, and a second mode in which the layers, and thus the presentation of the energy filters or shutter components, appear opaque to the incident energy impinging on the energy incident side. The differing modes are selectable by electrically energizing, differentially energizing and/or de-energizing electric fields in a vicinity of the energy scattering layers, including electric fields generated between a pair of transparent electrodes sandwiching an energy scattering layer.

  • Patent number: 11287673
    Abstract: An ophthalmic lens apparatus has a visual field of a plurality of horizontal meridians each having constant optical power. The optical power of the visual field continuously varies from a top portion of the lens to a bottom portion of the lens by the horizontal meridians being arranged with their midpoints along a generally vertical focal length deceleration curve across the visual field and at least some adjacent horizontal meridians having different optical powers. widths of the horizontal meridians across the lens decrease from a top end of the focal length deceleration curve toward a bottom end of the focal length deceleration curve, and the lens surface beyond the horizontal ends of the meridians provides visual comfort to a user of the lens by providing smooth gradients of defocus without sharp edges, image jumps, waviness or distortions of image.
