Provided is an optical material composition, with which an optical material is obtained having excellent quality such as excellent color tone and lightfastness, a low level of striae, and high transparency when polymerization-cured. Through use of the optical material composition, which includes a compound represented by formula (1) and an episulfide compound represented by formula (2), the ratio of the compound represented by formula (1) to the combined total amount of the compound represented by formula (1) and the episulfide compound represented by formula (2) being 0.001-5.0% by mass, it is possible to provide an optical material composition for manufacturing an optical material having a high refractive index, the optical material having excellent quality such as transparency, striae, color tone, and lightfastness. (In the formula, m represents an integer of 0-4, and n represents an integer of 0-2.)
A composition for optical material, which comprises a compound represented by the following formula (1) and an episulfide compound represented by the following formula (2), wherein the content of the compound represented by formula (1) is 0.001% to 5.0% by mass relative to the total mass of the compound represented by formula (1) and the episulfide compound represented by formula (2):
