Abstract

Described herein are water-soluble UV-absorbing vinylic monomers and their uses in preparing UV-absorbing contact lenses capable of blocking ultra-violet (“UV”) radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV radiation and potentially from violet radiation. This invention also provides a UV-absorbing contact lens.
