ABSTRACT An ophthalmic lens embodying an organic plastic lens member having a refractive index of at least 1.56 and being the cured product of a monomeric formulation. The formulation contains a resin monomer base, a curing agent selected from aromatic anhydrides, aromatic diamines, thioamides and thioamines, and a refractive index enhancing additive selected from alkyl or aromatic diols or thiols and transition metal alkoxides. The organic plastic lens member may be an integral, monofocal lens, or a segment embedded in a cavity in the front, convex surface of an organic plastic, major lens member having a lesser refractive index. The latter may have a thin, inorganic glass lens member adhered to its front, convex surface to produce a glass-plastic, laminated, multifocal lens structure.
