    摘要: A multifocal contact lens has diffractive power arising from a series of concentric zones each providing an asymmetric retardation of light across the zone width to direct light predominantly into a required order and sign of diffraction. At least some of the concentric zones are shaped so that the step height varies so that it is different in one region (A) of the lens from that in another region (B), whereby the intensity of light associated with an image observed by diffraction at one order in that region (A) of the lens is greater than the light intensity associated with the same image when observed at the same order through another region (B) of the lens.

    摘要: A contact lens of generally disc-like configuration having a central axis extending through the contact lens and about which the contact lens is substantially symmetric in configuration. The contact lens has
    a pupil zone through which the central axis extends and which comprises the area immediately circumferentially surrounding the central axis; an iris zone, which comprises the area circumferentially surrounding the pupil zone; and a peripheral zone which comprises the area circumferentially surrounding the iris zone and extends to the edge of the contact lens; Further in the area immediately adjacent to the periphery of the iris zone and the contact lens and circumferentially extending therearound a band of dark substantially light-absorbing colour is provided.

    摘要: A molded plastic cosmetic contact lens made in a repetitive manner compris­ing a cosmetic pattern of clustered networks of interconnected thin colored lines radiating from and about the periphery of the pupil portion in a direction inclined towards and in contact with the periphery of the iris portion and residing within the iris portion. The lens can be made by molding in a manner that the cosmetic pattern becomes part of the body of the lens.

    摘要: An interpenetrating network copolymer, method of producing same, and method of producing optical lens blanks and finished lenses therefrom. The method broadly involves the preparation of first, and second mixtures of polymerizable vinyl monomers and interrupting the polymerization of the first mixture at a relative viscosity of from about 1.05 to about 10 by admixing the partially polymerized first mixture with the second mixture to create a casting solution and thereafter, when desired, polymerizing molded casting solution in heat to create a solid lens material.
