Provided is a polymerizable composition including (meth)acrylate monomers having at least two sulfide (-S-) linkages in the monomer. The polymerizable compositions include a first (meth)acrylate monomer represented by the following Formula (I),where L1 is selected from a multivalent optionally substituted hydrocarbyl group optionally interrupted with at least one of -C(O)-, -S-, -O- and combinations thereof, and a divalent linking group represented by the following Formula (A).In Formula (A), Y is O or S. Also in Formula (I), L2 is independently for each n a divalent optionally substituted hydrocarbyl group optionally interrupted with at least one of -O- and -S-, R1 is independently selected for each n from hydrogen and methyl, and n is from 2 to 6. The polymerizable compositions also may include a polymerization moderator. Also provided are polymerizates including photochromic articles and optical elements prepared from such polymerizable compositions.
