Abstract

The present invention refers to a method for manufacturing a spectacle lens, the method comprising the step of curing a structured coating material on a surface of a spectacle lens, said structured coating material resulting in a structured coating on said surface of said spectacle lens, a structure of said structured coating providing a reduced light reflection to said spectacle lens, said structured coating material being a coating material, said coating material resulting in a coating providing an enhanced hydrophobicity to said spectacle lens, irrespective of said structure of said structured coating, the method being characterized in that said coating material resulting in said coating provides an enhanced abrasion resistance to said spectacle lens, irrespective of said structure of said structured coating.

Anti-reflective coating

An antireflective, antiglare or anti-reflection (AR) coating is a type of optical coating applied to the surface of lenses, other optical elements, and photovoltaic cells to reduce reflection. In typical imaging systems, this improves the efficiency since less light is lost due to reflection. In complex systems such as cameras, binoculars, telescopes, and microscopes the reduction in reflections also improves the contrast of the image by elimination of stray light. This is especially important in planetary astronomy.

Optical coating

An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflective coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and camera lenses. Another type is the high-reflector coating, which can be used to produce mirrors that reflect greater than 99.

Coating

A coating is a covering that is applied to the surface of an object, usually referred to as the substrate. The purpose of applying the coating may be decorative, functional, or both. Coatings may be applied as liquids, gases or solids e.g. Powder coatings. Paints and lacquers are coatings that mostly have dual uses of protecting the substrate and being decorative, although some artists paints are only for decoration, and the paint on large industrial pipes is for preventing corrosion and identification e.g.
