20150306827 | Apparatus and Method for Surface Rehabilitation - A lens refinishing process includes preparing the surface of the lens, determining whether to coat the lens with a polymer coating or polish the lens, either applying a polymer coating to the lens or polishing the lens, and then applying a protective coating. The preparation step includes applying a removal compound to the lens to remove an anti-reflective coating and to create nano-scratches, applying a coupling agent to the exposed substrate, and heating the coupling agent. The polishing step includes iteratively polishing the substrate using different combinations of polishing compound with different grit values together with different types of polishing pads. | 10-29-2015 |
