Abstract
Optical materials which are cured compositions of a mixture of (a) a compound comprising sulfur and (b) an inorganic compound comprising at least one atom selected from the group consisting of sulfur atom and selenium atom, the optical material being obtained by curing the compositions by polymerization. Optical materials having a large refractive index and a large Abbe number are obtained from the compositions.
