| abstract | An object of the present invention is to provide a composition for optical materials containing polythiol, which enables prediction of the presence or absence of cloudiness after polymerization and curing and judgment of quality in a stage before polymerization and curing. According to the present invention, an optical material composition containing an episulfide, a polythiol having an initial turbidity value of 0.5 ppm or less and a turbidity value of 0.6 ppm or less after being stored at 50 ° C. for 7 days, etc. This solved the problem. That is, in the optical material manufactured from the composition for optical material containing the polythiol that satisfies the above-mentioned conditions for the turbidity value, white turbidity is prevented and good transparency is realized. |
