Patents by Inventor Michel-René Christmann

Michel-René Christmann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11958305
    Abstract: A method of producing a spectacle lens includes providing a substrate having a front surface and a back surface and coating or covering at least one of the front surface or the back surface of the substrate, in full or in part, with a layer. The surface topography of the substrate surface is changed by bringing the surface into contact with a medium and the medium is removed. A product made according to the method and including (i) a spectacle lens or (ii) a representation of the spectacle lens in the form of computer-readable data present on a data medium or (iii) a data medium including a virtual representation of the spectacle lens in the form of computer-readable data or (iv) a representation of the spectacle lens in the form of a computer-readable data signal, is also disclosed.

  • Patent number: 11926557
    Abstract: A method for manufacturing a spectacle lens having a lens substrate and at least one coating is disclosed. The method includes providing a lens substrate having an uncoated or precoated front surface and an uncoated or precoated back surface, applying at least one coating to at least one of the surfaces of the lens substrate, the surface of the at least one coating being modifiable when contacted with at least one medium able to modify the surface of the at least one coating, contacting the surface of the at least one coating, partially or completely, with the at least one medium, considering the individual peripheral refraction, obtaining the spectacle lens having the lens substrate and the at least one coating, the surface of the at least one coating being modified according to the individual peripheral refraction.

  • Publication number: 20230256692
    Abstract: A method for manufacturing a spectacle lens including a lens substrate and at least one coating is disclosed. The method includes at least the following steps of providing a lens substrate comprising an uncoated or precoated front surface and an uncoated or precoated back surface, covering at least one of the surfaces of the lens substrate partially or completely with at least one coating composition, drying and/or precuring the at least one coating composition, contacting the surface of the at least one coating composition with at least one mechanical means, curing and/or hardening the at least one coating composition and obtaining a spectacle lens comprising a lens substrate and at least one coating, the surface topography of the at least one coating being modified by the at least one mechanical means.
