A composition comprising a polymer backbone and at least one side group, wherein the side group comprises a benzene ring-based chromophore comprising a ketone at the 1- position, a substituted or unsubstituted amino group at the 2-position, and an oxygen atom at the 3-position of the benzene ring having the following formula: wherein R1 is H, an alkyl group, or comprises an amino acid moiety or derivative thereof; R2 and R3 are individually H, alkyl, or any moiety with a vinyl functionality; R4 is an alkyl group, any moiety with a vinyl functionality, a counterpart alkylßne group, or a sugar moiety; and X is an optional electron-donating group linked to the benzene ring at the 4, 5, or 6 position. The chromophore is a kynurenine-based compound. Methods of making and using the composition are also provided. The composition can be used in an ophthalmic lens or device for protecting the retina by blocking UV rays and filtering violet rays. |
