1. An optical material comprising:
a polymer that comprises a sulfoxide structure in a main chain, and a substituted aromatic ring structure in the main chain,
wherein the main chain of the polymer comprises a constituent unit (A) represented by the following formula (1):

OG Complex Work Unit Chemistry
wherein A1 is a substituted divalent aromatic hydrocarbon group that is selected from the group consisting of a phenylene group, a naphthylene group, an anthrylene group, a biphenylene group, and a triphenylene group, and
wherein a substituent of the substituted divalent aromatic hydrocarbon group is selected from the group consisting of a halogen atom, a hydroxy group, an optionally substituted C1-C18 alkyl group, an optionally substituted C1-C18 alkoxy group, an optionally substituted aryl group, an optionally substituted aralkyl group, and an optionally substituted sulfur-containing substituent and wherein the optical material has an Abbe number in the range of 10 or greater and an Abbe number in the range of 60 or less.
