  • Publication number: 20220137263
    Abstract: The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.

  • Publication number: 20220032564
    Abstract: The invention is related to a coated contact lens, especially a coated silicone hydrogel contact lens, which comprises an anterior surface, an opposite posterior surface, and a layered structural configuration from the anterior surface to the posterior surface. The layered structural configuration comprises an outer anterior surface hydrogel layer, an inner layer, and an outer posterior surface hydrogel layer. The inner layer is a lens bulk material. The coated contact lens has a superior lens surface softness and a good lens surface hydrophilicity while optionally having a desirably-lower polyquaternium-1 uptake.

  • Publication number: 20210132411
    Abstract: The invention is related to a contact lens, especially a SiHy contact lens, which comprises a lens bulk material covered with an outer surface hydrogel layer thereon and has a posterior surface and an opposite anterior surface. The outer surface hydrogel layer consists of an anterior outer hydrogel layer and a posterior outer hydrogel layer. A contact lens of the invention is characterized by having a difference in surface softness between its posterior (BC) and anterior (FC) surfaces.

  • Patent number: 10996492
    Abstract: A method of manufacturing a colored contact lens including the steps of providing a transparent contact lens having a pupil section and an iris section, the iris section surrounding the pupil section and applying a colorant to the surface of the contact lens. The colorant is applied to the contact lens as an amorphous pattern and covers an effective amount of the iris section of the same. The amorphous pattern provides a lens capable of changing the apparent color of the iris of a person wearing the lens while imparting a very natural appearance.

  • Patent number: 10589479
    Abstract: The invention is generally related to colored contact lenses which comprise a hydrogel lens body having an opaque color image therein and/or thereon and a durable lubricious coating thereon. The coating comprises an anchoring layer of a polyanionic polymer having carboxyl groups and a hydrogel layer which is derived from a hydrophilic polymeric material having azetidinium groups and is covalently attached onto the anchoring layer of the polyanionic polymer through linkages each formed between one carboxyl group and one azetidinium groups. The colored contact lens has a surface lubricity better than the lubricity of the non-silicone hydrogel lens body and a friction rating of about 2 or lower after 7 cycles of manual rubbing.

  • Patent number: 10525158
    Abstract: The present invention is generally related to a lens care system and method for disinfecting and cleaning contact lenses. A lens care system or method of the invention is based on electrolysis of an aqueous chloride solution for generating germicide species (e.g., chlorine, hypochlorous acid, hypochlorite, or combinations thereof) and subsequent in-situ electrolysis of hypochlorous acid or hypochlorite in the aqueous solution for neutralizing the generated germicide species.
