Title
(EN) UV/VISIBLE LIGHT ABSORBERS FOR OPHTHALMIC LENS MATERIALS
(PT) ABSORVEDORES DE LUZ UV/VISÍVEL PARA MATERIAIS DE LENTES OFTALMOLÓGICAS
Abstract
(EN)
Benzotriazole UV/Visible light-absorbing monomers are disclosed. The UV/Vis absorbers are particularly suitable for use in intraocular lens materials.
