  • Patent number: 10364365
    Abstract: The present invention provides an actinically or thermally curable ink for making colored silicone hydrogel contact lenses. The ink of the invention comprises at least a pigment, a polymeric dispersant, a solvent and an actinically or thermally curable silicone-containing binder polymer including ethylenically unsaturated groups and segments derived from at least one silicone-containing vinylic monomer or macromere. The ink of the invention is characterized by having capability to be cured actinically or thermally to form a colored coat on a silicone hydrogel contact lens, wherein the ink is characterized by having an longer print life using a pad-printing system by at least 30% comparing to the ink which has the same composition except of no polymeric dispersant, wherein ink life is a number of printed parts that can be achieved in a print cycle.

  • Patent number: 10156736
    Abstract: The invention is directed to a colored contact lens designed for making a wearer's eyes to appear larger and more defined and with more shine, while remaining natural by blending seamlessly with the eye. A colored contact lens, comprising a first print of a first color and a second print of a second color, wherein the first print is an annular ring of gradient dot matrix, wherein the second print is an annular ring of speckle pattern, wherein the annular ring of speckle pattern comprises clusters of regular or irregular shapes distributed annularly, wherein the regular or irregular shapes consists of a large number of circular dots, wherein the annular ring of speckle pattern has non-smooth inner and outer borders, wherein the second print is located on the inside of the first print, wherein 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.

  • Patent number: 9575333
    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 wearers 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.
