Optical polymer and lens including same

A lens comprising an optical polymer, wherein the optical polymer comprises a repeating unit represented by the following Formula 1:

• where R1 to R3 are each independently hydrogen, deuterium, halogen, or an organic group comprising any one selected from a substituted or unsubstituted C1-C60 alkyl group, a substituted or unsubstituted C3-C60 cycloalkyl group, a substituted or unsubstituted C1-C60 alkoxy group, a substituted or unsubstituted C6-C60 aryl group, and a substituted or unsubstituted C2-C60 heteroaryl group comprising at least one hetero atom selected from the group consisting of N, O, and S, where A1 is a single bond, an oxygen atom, or a sulfur atom, A2 is an oxygen atom or a sulfur atom, B1 and B2 are each independently a single bond or an organic group represented by the following Formula 2, and n represents an integer of 5 or more and 500 or less:
• -al-D-al- [Formula 2]
• where al is a C1-C8 alkylene group, and D is —S(═O)2—X—, —X—S(═O)2—, —S(═O)2—X—S(═O)2—, —C(═O)—X—, —X—C(═O)—, —C(═O)—X—C(═O)—, carbonyl, alkenylene, alkynylene, ester, or ether, wherein X is a C6-C60 arylene group.
