Abstract: The disclosure provides a novel method for producing a polymerizable composition for optical materials, in which the occurrence of gelation is suppressed even though an organophosphorus compound is used during the preparation of a polymerizable composition for optical materials of a thiourethane-based resin having a high refractive index and suppressed coloration, and the like. A method for producing a polymerizable composition for optical materials, including: a step of providing an organophosphorus compound, a polyisocyanate, a first polythiol, and a second polythiol; and a step of mixing the polyisocyanate and the first and second polythiols in the presence of the organophosphorus compound to obtain a polymerizable composition for optical materials, wherein, in the mixing step, the polyisocyanate and the first polythiol are mixed, and then the second polythiol is further added and mixed.

Abstract: A polarizing film having a molded shape, in which a difference in average transmittance of the polarizing film at a wavelength of 400 to 700 nm is 5% or less before and after molding the shape of the polarizing film. In addition, when molding the polarizing film into a shape such as a curved surface, the polarizing film is heat-treated in a temperature range of Tg−20° C. or higher and Tg+10° C. or lower, where Tg is a glass transition point of a resin constituting the polarizing film. Further, one chamber is divided into a first space and a second space by the polarizing film disposed in the chamber, and the polarizing film is transfer-molded along a molding surface by a differential pressure generated by making a pressure in the first space and a pressure in the second space different from each other.

Abstract: A spectacle lens can inhibit ametropia of the eyes and ensure full visibility. The spectacle lens comprises: first refraction areas and second refraction areas. Each first refraction area has a first refraction force that may be based on a prescription for correcting the ametropia of the eyes. Each second refraction area has a refraction force different from the first refraction force and may function to focus images on the positions except the retina of the eyes, to inhibit the development of the ametropia. Near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.
