The present invention relates to a composition for optical materials, comprising (a) a compound having in one molecule at least one structure represented by the following Formula 1: wherein R<SUP>1 </SUP>is a single bond or a C<SUB>1-10 </SUB>hydrocarbon group, each of R<SUP>2</SUP>, R<SUP>3 </SUP>and R<SUP>4 </SUP>is a C<SUB>1-10 </SUB>hydrocarbon group or hydrogen, Y is O, 5, Se or Te, m is 1 to 5, and n is 0 to 5; (b) a compound having in one molecule at least one isocyanate group and/or at least one isothiocyanate group; (c) a compound having in one molecule at least one mercapto group; and (d) an inorganic compound having sulfur atom and/or selenium atom, and also relates to an optical material produced by polymerization curing the composition, a production method thereof, and an optical lens comprising the optical material. The present invention provides a high refractive, high Abbe's number optical material having an improved impact resistance.
