According to the present invention, there is provided a composition for an optical material comprising an episulfide compound represented by the following formula (1) and an episulfide compound represented by the following formula (2). By using the composition for an optical material, it is possible to suppress a decrease in yield due to mold release failure, and to obtain an optical material excellent in dyeability.n□n(where m and p are integers from 0 to 4, and n and q are integers from 0 to 2)n□n(where m is an integer from 0 to 4, and n is an integer from 0 to 2) |
