A method of making opthalmic lenses is disclosed comprising the steps of forming at least a major body portion of a first lens body from a transparent plastic resinous material having an index of refraction greater than that of crown glass, rough shaping the first lens body portion to provide the lens configuration, selecting first and second thin plano glass shields having the respective shapes to form the different sides of the main body portion, shaping the first lens body portion between the shields by means of pressure and bonding each of the shields to the respective sides of the first lens portion.
