<p>Acrylic, high refractive index ophthalmic device materials comprising an aryl acrylic monomer, a first stage polymerization initiator and a second stage cross-linking agent are prepared in a two-stage method. The monomers used to form the ophthalmic device materials do not contain cross-linking agents having more than one unsaturated bond. In the first stage of the method, the materials are polymerized. In the second stage, the materials are cross-linked by exposure to heat.</p> |
