Abstract: A method for forming sunglass lenses with a predetermined optical gradient, namely a polarized gradient, or transmissivity gradient in which a gradient pattern is provided on an oriented sheet. The oriented sheet is incorporated into a lens to provide the lens with the associated gradient.

Abstract: The disclosure is related to a polymerizable composition for coloring contact lens, comprising a composite colorant and at least one hydrophilic monomer. The composite colorant is produced by a reaction of a colorant precursor and a (methyl)methacryloxy group-containing silane coupling agent. The colorant precursor is produced by a reaction of a metal oxide and a siloxane compound under alkaline solution.

Abstract: The invention is directed to a colored contact lens designed for making a wearer's eyes to appear larger, bolder, and enhanced color while giving the wearer's eyes a very natural appearance. A colored contact lens of the invention comprising a first print of a first color and a second print of a second color, wherein the first print consisting of an annular ring of gradient dot matrix, wherein the second print comprises a limbal ring and an outer starburst pattern, wherein the limbal ring surrounds the outer starburst pattern, wherein the annular ring and the limbal ring have a substantially identical outer diameter and the annular ring has a larger inside diameter than the limbal ring, the first color and the second color are different or the same, wherein the first print and the second print are concentric with the center of contact lens.
