Intraocular lenses containing a photochromic agent, are disclosed. Specifically, the foldable intraocular lens of the present invention comprises an optic body made from a crosslinked material comprising at least one monomer, a crosslinker, a UV absorber, and a photochromic agent which has a maximum absorption peak of about 400-500 nm in its excited state. The lens has a glass transition temperature of about 37° C. or lower. Methods for making these intraocular lenses are also taught.L'invention concerne des lentilles intraoculaires contenant un agent photochromique qui présente un pic d'absorption maximum situé dans la plage de longueur d'onde comprise entre environ 400 et 500 nm. L'invention concerne également des procédés de production desdites lentilles intraoculaires.
