  • Method for making multifocal ophthalmic lens
    Patent number: 4576623
    Abstract: A laminated multifocal prescription ophthalmic lens is provided comprising a plano (zero power) cap element incorporating a convergent near-vision multifocal segment, the cap being cemented to a prescription-ground single vision base element. The back surface curvature of the base is configured to provide prescribed sphere, cylinder and other vision-corrective refraction characteristics to the laminated lens.

  • Method for making colored photochromic prescription ophthalmic lenses
    Patent number: 4498919
    Abstract: Colored photochromic ophthalmic lenses are produced by combining a photochromic cap element having an integrally colored back surface with an ophthalmic crown base element having a prescription-ground back surface, the cap back and base element front surfaces having been finished to a matching standard base curvature, thus providing a cemented assembly exhibiting a selected combination of prescribed vision-correcting and light filtering properties.

  • Process for making multifocal photochromic ophthalmic lens
    Patent number: 4017292
    Abstract: Multifocal photochromic opthalmic lenses are produced by nucleating potentially photochromic major lens blanks through heat treatment, combining the nucleated blanks with compatible button or segment glasses, and fusing the combined glasses at temperatures suitable for achieving both fusion and the simultaneous development of full photochromic properties in the previously nucleated major lens blanks.
