    摘要: A method of producing an optical material, which comprises a step of preparing a polymerizable composition containing a polythiol composition and a polyiso(thio)cyanate compound; a determination step which comprises measuring a content of a solvent A which is at least one selected from the group consisting of toluene, acetone, and N,N-dimethylformamide, in the polymerizable composition to check whether the content of the solvent A is within a range of from 0.10% by mass to 1.70% by mass, and, in a case in which the content of the solvent A is within a range of from 0.10% by mass to 1.70% by mass, determining the polymerizable composition as a polymerizable composition for an optical material; and a step of injecting the polymerizable composition for an optical material into a mold for resin molding and curing the same, thereby obtaining an optical material as a resin-molded product.
