The present invention relates to a composition for optical material capable of suppressing the occurrence of polymerization unevenness called striae, particularly striae in a lens having a high frequency and a tight curve, and more specifically, dibutyltin dichloride and monobutyltin trichloride. An optical material composition comprising a stabilizer having a mass ratio of 97.0 / 3.0 to 100.0 / 0.0 with chloride, an episulfide compound, a polythiol compound, and a polymerization catalyst for the episulfide compound. It is about. |
