The present invention relates to a thioepoxy compound for an optical material, a polymerizable composition including the thioepoxy compound, and a method for producing a thioepoxy optical material by polymerization of the polymerizable composition. The polymerizable composition further includes 4.1 to 15% by weight of 2,3-epoxypropyl(2,3-epithiopropyl)sulfide and/or 2,3-epoxypropyl(2,3-epithiopropyl)disulfide. The thioepoxy optical material is free from color instability, demolding, and polymerization imbalance, which are problems encountered in general thioepoxy optical materials.
