    Abstract: A polymerizable composition for optical components, which can prevent striae while keeping strength for optical components when a thick optical component is produced. A polymerizable composition for optical components is a mixture of a first composition including a polyisocyanate compound (A) and a second composition including a polythiol compound (B1) and a thiol group-containing substance (B2), the composition includes the thiol group-containing substance (B2) showing peak at a position at retention time three minutes or more from a peak of the polythiol compound (B1) in a chromatogram obtained by analyzing the composition by high performance liquid chromatography (HPLC) analysis, and the ratio (A/B1) is 80/100 to 95/100, wherein the equivalent ratio (A/B1) is an equivalent A of the polyisocyanate compound (A) using a weight and group number of the polyisocyanate compound (A) to B1 of the polythiol compound (B1) using a weight and group number of the polythiol compound (B1).
