Zusammenfassung:	To provide a curable composition which produces a cured product with a low specific gravity and high refractive index; a cured product derived from the curable composition; and an optical article, a lens, and spectacles, each comprising the cured product.SOLUTION: An embodiment of the present invention is a curable composition. The curable composition contains a sulfur-containing compound represented by formula (I) and a styrene compound. The styrene compound contains at least one selected from the group consisting of styrene and styrene derivatives. In formula (I), R1 represents a linear thiol alkylene group having one or more sulfur atoms. R2 and R3 independently represent a hydrogen atom, a methyl group, or an ethyl group.SELECTED DRAWING: Figure 1 【課題】本発明の目的は、低比重かつ高屈折率な硬化体を実現可能な硬化性組成物と、この硬化体と、硬化体を含む光学物品、レンズ及び眼鏡とを提供することにある。【解決手段】実施形態によると、硬化性組成物が提供される。硬化性組成物は、式（Ｉ）に表される硫黄含有化合物と、スチレン化合物とを含む。スチレン化合物は、スチレン及びスチレン誘導体からなる群より選ばれる少なくとも１種を含む。式（Ｉ）において、Ｒ１は、１以上の硫黄原子を含む鎖状チオアルキレン基である。Ｒ２及びＲ３は、それぞれ独立に、水素原子、メチル基、又はエチル基である。【選択図】図１
