Abstract

A method of manufacturing a spectacle lens having a lens substrate a lens substrate and at least one coating is disclosed. The method includes at least the following steps in the given order: providing a lens substrate having an uncoated or pre-coated front surface and an uncoated or pre-coated back surface, coating at least one surface with at least one coating, the surface of the at least one coating being modifiable when contacted with at least one medium being able to modify the surface of the coating, completely or partially contacting the surface of the coating with the at least one medium, applying at least one single electromagnetic pulse to at least one of the surfaces of the spectacle lens having the lens substrate, the coating and the medium and obtaining the spectacle lens having the at least one coating with a completely or partially modified surface.

Dependent claims

A method of manufacturing a spectacle lens, the spectacle lens having a lens substrate and at least one coating, the method comprising at least the following steps:

providing a lens substrate having an uncoated or precoated front surface and an uncoated or precoated back surface;
coating at least one surface of the lens substrate with at least one coating;
and
completely or partially contacting a surface of the at least one coating with at least one medium,
wherein the method further comprises at least:
applying at least one single electromagnetic pulse to at least one of the surfaces of the spectacle lens having the lens substrate, the at least one coating and the at least one medium;
removing the at least one medium;
and
obtaining the spectacle lens having at least one coating with a completely or partially modified surface, the surface of the at least one coating being modifiable when in contact or having been in contact with the at least one medium, and the at least one medium being configured to modify the surface of the at least one coating.
