Abstract
Hydrophilic UV light absorbing polymerizing monomers are provided. These monomers are copolymerizable for providing biocompatible hydrogels capable of absorbing at least 90% of the UV light incident to the hydrogels. Such hydrogels are optically transparent, have high refractive indices, and possess long term stability. The hydrogels provided are useful in all applications where hydrogels may be used including intraocular lenses, corneal inlays, corneal onlays, contact lenses and similar applications.
