Compared with glass, optical resin materials have the advantages of light weight, easy dyeing and not easy to break. The sulfide resin optical materials obtained by polymerization of episulfide compounds have the characteristics of high refractive index and high Abbe number. They have been used in the preparation of high refractive index optical resin lenses with a refractive index of 1.70 or above. SINOMER® OM835 is the main raw material for synthesizing high refractive resins.
