  • Patent number: 11938696
    Abstract: A method for manufacturing a coated lens by applying at least one single electromagnetic pulse to convert a coating precursor material into at least one coating. The electromagnetic pulse is delivered to the coating precursor material applied on a surface of an uncoated or precoated optical lens substrate. The at least one single electromagnetic pulse is applied from an electromagnetic source such as a flash lamp, a halogen lamp, a directed plasma arc, a laser, a microwave generator, an induction heater, an electron beam, a stroboscope, or a mercury lamp.

  • Patent number: 11899287
    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.
