Abstract
A method for making improved optical quality lenses is described. The method includes arranging a mold having a molding surface, a curable optical quality resin composition, and a plastic lens preform of optical quality material such that the resin composition is disposed between, and in contact with, the plastic lens preform and the mold. Upon curing, the resin composition forms a cured plastic attached portion that is bonded to the plastic lens preform. The resin composition and plastic lens preform are selected such that the attached portion has a higher scratch resistance, a lower chromatic aberration, and/or a higher ease of edging than the lens preform.
