  • Patent number: 6986579
    Abstract: A method of manufacturing an electro-active lens is disclosed. The lens is manufactured by providing a lens blank having a front and back surface, a thickness, and an index of refraction. An electro-active element is placed on one of the front or back surfaces of the lens blank. A covering surface is then formed over the surface of the lens blank containing the electro-active element. In some embodiments, the electro-active lens may then be surfaced to provide a desired fixed optical power and edged to fit within a spectacles frame.

  • 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.

  • Patent number: 6857741
    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: 20040156021
    Abstract: An electro-active phoropter and a method of using the electro-active phoropter to measure a patient's vision prescription is disclosed. The electro-active phoropter includes a series of individually addressable electro-active lenses. The lenses have either a positive or negative optical power when an electrical potential is applied across the lens and a neutral optical power when no electrical potential is applied across the lens. Each lens provides an optical power that is part of a net optical power of the series of lenses when a patient views through the phoropter. The optical power of the phoropter can be incrementally adjusted by changing the distribution of the electrical potential across the different lenses of the series to provide increasing or decreasing optical power until a patient achieves a desired level of clarity and a vision prescription has been determined.
