Abstract:
A method for making improved optical quality lenses is described which 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.
