A Comparison And Evaluation Of Aspheric Lens Designs.

Six aspheric, single vision lens designs, were subjectively and objectively compared by four non-presbyopic, hyperopic patients. The lenses chosen were Sola Optical's ASL Polycarbonate and Spectralite, Rodenstock's Cosmolit, American Optical's Aspherlite, Silor Optical's Hyperal, and Gentex Optic's Profile. The subjects were previously wearing spherical design single vision spectacles or contact lenses to correct their ametropia. Two of the four subjects preferred the Spectralite Aspherics overall, while the remaining two subjects preferred their habitual contact lenses.
