  • Patent number: 5432623
    Abstract: A lens design consisting of a multi-component assembly, with one of the said components being a (decorative) hologram. The said assembly being comprised of an optical-quality holographic recording material coating applied to the inner or outer surface of a primary lens element, upon which a hologram may then be recorded in-situ, and may be used alone, or be optically contacted to a secondary lens element to form a unitary assembly of high optical quality and clarity, with the holographic recording material being encapsulated between the primary and secondary elements. The said lens assembly may be of simple or compound curvature, and be used in functional, prescription-quality eyewear of single or multi-lens type. Also, one or more of the lens components, other than the hologram, may function in a light-filtering role, so as to visually eliminate unwanted images or colors to the wearer, and further allow such lens assemblies to be used in sunglasses.
