Abstract: A method for producing an optical silicone assembly is disclosed. The method comprises the steps of: i) treating a surface of a substrate with an optically clear silicone adhesive composition; ii) placing the substrate obtained by step i) into a mold; iii-a) injecting an optically clear moldable silicone composition into the mold, and/or iii-b) overmolding the optically clear moldable silicone composition onto the substrate; and then iv) heating the optically clear moldable silicone composition to form the optical silicone assembly. The optical silicone assembly produced by the method of this disclosure is characterized by excellent adhesion of an optical silicone product to various types of substrates.

Abstract: A cationic contact lens is described as well as methods of manufacturing the same. The cationic contact lens includes a polymeric lens body that is the reaction product of a polymerizable composition that includes at least one siloxane, at least one nonionic hydrophilic monomer and at least one acyclic tertiary amine monomer. The cationic contact lens can be an unworn sterile silicone hydrogel contact lens. The contact lens is capable of substantially linear release of a releasable anionic agent and the at least one acyclic tertiary amine monomer facilitates uptake and/or sustained release of the releasable anionic agent by the polymeric lens body. The contact lens can be present in a sealed contact lens package. The sealed contact lens package can include at least a) a base member having a cavity; b) a contact lens packaging solution in the cavity; c) a unworn sterile contact lens immersed in the contact lens packaging solution in the cavity with the releasable anionic agent present; and d) a cover that forms a liquid-tight seal with the base member.

Abstract: Provided is a resin that can simultaneously achieve a high refractive index, high heat resistance, and low birefringence. A hydrogenated cycloolefin copolymer is obtained through hydrogenation of a cycloolefin copolymer that includes a structural unit derived from 1-naphthylnorbornene and a structural unit derived from 2-naphthylnorbornene, wherein an average endo isomer ratio of the 1-naphthylnorbornene and the 2-naphthylnorbornene is 50 mol % or more. The hydrogenated cycloolefin copolymer is suitable for use as a material of an optical element such as an optical lens.
