Abstract

Benzotriazole vinylic monomers having an increased solubility in ophthalmic device material formulations relative to certain other benzotriazole vinylic monomers are disclosed. Such benzotriazole vinylic monomers are useful for fabricating various ophthalmic devices including hydrogel contact lenses such as silicone hydrogel contact lenses and can have a high relative ultraviolet and / or High-energy visible light (UV / HEVL) absorption.
