发明名称 CONTROLLED SURFACE OPTICAL LENS AND METHOD OF SURFACE ALTERATION
摘要 An optical lens of an acrylic polymer having an outermost surface modified in morphology to possess desired characteristics of low surface energy and high biological inertness. The modified surface is achieved by removing only molecular level irregularities in the outermost surface of an acrylic polymer optical lens body. The surface removal and smoothing process involves the steps of surface preparation and surface passivation. In surface preparation, the surface of the lens body is treated to render it wettable by a surface passivation reagent. In surface passivation, the surface prepared optical lens body is immersed in a surface passivation reagent which removes weakly bound water molecules from the outermost surface of the lens body and reorganizes or smoothes at the molecular level irregularities at the surface of the optical lens body.
