Light filters comprising a naturally occurring chromophore and derivatives thereof

摘要

A composition comprising a polymer backbone and at least one side group, wherein the side c/oup 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. 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.
