The present invention provides a material for intraocular lenses which has improved hydrolysis resistance. This material for intraocular lenses is obtained by polymerizing a monomer composition containing: base monomers including an aromatic ring-containing acrylate monomer and an alkoxyalkyl methacrylate monomer having an alkoxyalkyl group with four or fewer carbon atoms； a hydrophilic monomer； and a crosslikable monomer. The blending ratio on a molar basis of the methacrylate monomer to the acrylate monomer out of all the monomer components in the monomer composition is 0.25 to 1.00.
