a lens design consisting of a multi - component assembly , with one of the said components being a 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 . in addition , the said lens assembly may contain multiple images on the holographic recording material , which are visible to an observer during different periods of daytime sunlight , or under various artificial lighting conditions .
