  A cured matter obtained by polymerizing and curing a polymerizable composition comprising a compound having at least one episulfide in a molecule is reduced in an odor by adding a perfume to the polymerizable composition comprising the compound having at least one episulfide in a molecule. A cloudiness of the lens is removed by raising a purity of sulfur to 98% or more. A reduction in a chlorine content of the sulfur compound described above to 0.1% by weight or less elevates an oxidation resistance and a light fastness of the high refractive index optical material and improves a color tone thereof. An optical product having a high refractive index and a high-degree transparency is provided by subjecting the composition in advance to deaerating treatment at 0 to 100° C. for one minute to 24 hours under a reduced pressure of 0.001 to 50 torr.

  通过聚合和固化至少含有一种环硫醚的化合物的可聚合组合物获得的治愈物质，通过向至少含有一种环硫醚的化合物的可聚合组合物中添加香水来减少其气味。通过将硫的纯度提高到98％或更高，可以消除镜片的混浊。将上述硫化合物的氯含量降低至0.1％或更低可以提高高折射率光学材料的氧化抗性和耐光性，并改善其色调。通过在0至100°C下将组合物事先进行脱气处理，以在0.001至50 torr的减压下持续1分钟至24小时，可提供具有高折射率和高度透明度的光学产品。
