This invention relates to polymerizable ultraviolet light absorbers and yellow colorants and their use in ophthalmic lenses. In particular, this invention relates to polymerizable ultraviolet light absorbing methine compounds and yellow compounds of the methine and anthraquinone classes that block ultraviolet light and/or violet-blue light transmission through ophthalmic lenses. L'invention concerne des absorbeurs de rayonnements ultraviolets polymérisables et des colorants jaunes et leur utilisation dans des lentilles ophthalmiques. L'invention concerne notamment des composés de méthine absorbant le rayonnement ultraviolet polymérisable et des composés jaunes de la méthine et des classes d'anthraquinone qui bloquent le rayonnement ultraviolet et/ou la transmission de rayonnement bleu-violet par les lentilles ophthalmiques.
