Abstract

The present application provides an optical material composition, comprising the following raw materials: a polysulfide compound, a polyisocyanate, a cyclic sulfur compound and a hydroxyl compound selected from two or more of pentaerythritol tri-(3-mercaptopropionic acid) ester, 8-mercapto-4-mercaptomethyl-3,6-dithia-1-octanol, (beta-cyclopropylthio)2-hydroxy-mercaptopropyl sulfide, 8-mercapto-5-mercaptomethyl-3,6-dithia-1-octanol and trimethylolpropane di-(3-mercaptopropionate). The present application also provides an optical material and an optical lens. The optical material composition provided by the present application comprises a hydroxyl compound, a polysulfide compound, a polyisocyanate compound and a cyclic sulfur compound, and the edge collapse problem of the material in the punching process is effectively improved by introducing two hydroxyl compounds.
