Abstract
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.
Claims21
A lens refinishing process, comprising:
- preparing the lens, wherein preparing comprises:
- applying an anti-reflective coating removal compound to a surface of the lens to remove an anti-reflective coating on the lens to expose an underlying substrate, and to create nano-scratches in a surface of the substrate,
- applying a coupling agent to the surface of the substrate, and
- heating the coupling agent;
- and
- coating the lens with a protective coating.
A device having a lens refinished according to the lens refinishing process comprising:
- preparing the lens, wherein preparing comprises:
- applying an anti-reflective coating removal compound to a surface of the lens to remove an anti-reflective coating on the lens to expose an underlying substrate, and to create nano-scratches in a surface of the substrate,
- applying a coupling agent to the surface of the substrate, and
- heating the coupling agent;
- and
