A lens including a polarizing film within a polyurethanic material which comprises a photochromic dye therein.

Polarized lenses with variable transmission

A lens is provided comprising a substrate, a first dielectric layer comprising a first dielectric material uniformly covering an outer surface of said substrate, a second dielectric layer comprising a second dielectric material uniformly covering said first metal layer, a metal layer comprising a metal material gradiently covering only a portion of said second dielectric layer and a third dielectric layer formed of a third dielectric material gradiently covering said metal layer.

Lenses having chromatic effect

A lens is provided comprising a substrate, a first metal layer comprising a first metal material uniformly covering an outer surface of said substrate, a first dielectric layer comprising a first dielectric material uniformly covering said first metal layer, a second metal layer comprising a second metal material gradiently covering only a portion of said first dielectric layer and a second dielectric layer formed of a second dielectric material gradiently covering said second metal layer.

A lens is provided comprising a substrate, a metal layer comprising a metal material uniformly covering an outer surface of said substrate, a first dielectric layer comprising a first dielectric material uniformly covering said metal layer and a second dielectric layer comprising a second dielectric material gradiently covering only a portion of said first dielectric layer.

A plano-convex optical sheet having a positive power including:

Optical sheet for use in manufacturing a cylindrically shaped optically correct visor and method of manufacturing said visor

A lens having a substrate, a metal layer uniformly covering one side of the substrate, a first dielectric layer uniformly covering the metal layer, and a second dielectric layer gradiently covering only a portion of the first dielectric layer.

An improved method for manufacturing spectacle lenses and the like from diglycol allyl carbonate or equivalent plastic by first heating the plastic monomer in the liquid state and containing a polymerization initiator therefor in a planar mold until a degree of polymerization in the range of about 65-85% of completion has been achieved, then removing the partially polymerized material from the mold, subjecting the same to deflection to a curvature corresponding to the desired lens and heating the thus-deflected material until polymerization is complete. Preferably, the initial planar molding step is carried out with a layer or sheet of the material of sufficient size as to contain a plurality of individual lens elements, and after removal thereof from the mold, a plurality of individual lens elements is derived therefrom and such elements are separately subjected to deflection and further polymerization. Preferably, the amount of polymerization initiator exceeds the normally used amount. A post thermal treatment is advantageous to stabilize the lens elements from loss of the curvature imparted thereto.
