Abstract:
The invention relates to transparent polymer material containing a dye which absorbs light above 400 nm. It furthermore relates to methods for producing the polymer material and a lens comprising the polymer material. In particular, the invention relates to an intraocular lens (IOL) suitable for implantation in mammals, which IOL has visible light transmission properties comparable to those of the human crystalline lens. Provided is a transparent polymer material containing at least one covalently attached dye, said dye having the general formula I:
