  • Patent number: 6927894
    Abstract: A mirror assembly including an active lens and a reflective surface. The mirror assembly may change its refractive index when a voltage is applied to the active lens, thereby changing the field of view in the lens. Exemplary applications include a blind spot system in a motor vehicle, in which, upon sensing another vehicle in a driver's blind spot, the mirror assembly changes the driver's field of view to include the blind spot. Additional applications include a magnifying mirror for shaving or applying cosmetics.

  • Publication number: 20050168687
    Abstract: A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.

  • Publication number: 20050140924
    Abstract: Electro-active multi-focal spectacles are disclosed. The spectacles have a stack of at least two electro-active regions. The electro-active regions produce a plurality of viewing correction zones. The spectacles also have a controller for independently activating the electro-active regions to produce viewing correction zones. An electro-active multi-focal spectacle having a blending zone is also disclosed. The blending zone provides a transition of optical power between viewing correction zones.

  • Publication number: 20050099594
    Abstract: An electro-active contact lens system and a method for making the electro-active contact lens system is disclosed. The system includes a contact lens, an electro-active element attached to the contact lens, a view detector attached to the contact lens and in electronic communication with the electro-active element, and a power source attached to the contact lens. In certain embodiments, the view detector may be a rangefinder which determines the distance of an object being viewed and these embodiments further include a means to stabilize the rangefinder between the opening of the eyelids when the electro-active contact lens system is worn by a wearer. The electro-active contact lens system provides electro-active vision correction of one or more focal lengths.

  • Patent number: 6871951
    Abstract: A system in accord with the present invention includes a first optical lens having a first outer surface, a second outer surface, and an outer perimeter, an electro-active refractive matrix; and a conductor coupled to the electro-active matrix. An alternative system in accord with the present invention includes a frame, the frame having a lens support and a temple region; an optical lens coupled to the lens support, the optical lens including an electro-active refractive matrix; a controller coupled to the electro-active refractive matrix; and a range finder coupled to the controller. The present invention also includes a method of assembling an optical lens system that comprises placing an electro-active refractive matrix into a cavity of a first optical lens; and covering at least a portion of the electro-active refractive matrix with a second optical lens.
