Patent number: 6965385Abstract: A method is provided for demonstrating an effect of a particular spectacle frame and of optical lenses fitted into this spectacle frame on the appearance of a spectacles wearer as it would be perceived by another person (virtual observer). An image of a face of the spectacles wearer is prepared in such manner that the image can be processes in a computer. An arrangement of the respective spectacle frame in front of the eyes is determined. The image of the face is projected onto a plane by a computation (ray-tracing) of principal rays passing through a center of rotation of an eye of the (virtual) observer to produce a planar image of the face in this plane.Type: GrantFiled: February 13, 2002Date of Patent: November 15, 2005Assignee: Rodenstock GmbHInventors: Andrea Welk, Helmut Altheimer, Peter Baumbach, Gregor Esser, Walter Haimerl

Patent number: 6964478Abstract: A spectacle lens is provided with a region (distance portion) designed for viewing at greater distances and, in particular, “to infinity”, a region (near portion) designed for viewing at short distances and, in particular, “reading distances”, and a progression zone disposed between the distance portion and the near portion, in which the power of the spectacle lens increases from the value in the distance reference point located in the distance portion to the value at the near reference point located in the near portion along a line (principal meridian) curving towards the nose. The invention is marked by specific conditions for the astigmatic deviation and/or the mean “as worn” power being observed.Type: GrantFiled: October 24, 2002Date of Patent: November 15, 2005Assignee: Rodenstock GmbHInventors: Andrea Welk, Peter Baumbach, Walter Haimerl, Herbert Pfeiffer, Gregor Esser, Helmut Altheimer, Rainer Dorsch, Martin Zimmerman, Norbert Awrath, Jochen Brosig, Werner Mueller, Martin Wechs, Stephan Haser, Winfried Nikolaus
