  • Controlling designs using a polygonal design
    Patent number: 9354455
    Abstract: A method and device for calculating design parameters of a design of a progressive spectacle lens on the basis of a predetermined design polygon. The design parameters are calculated by specifying a point within the design polygon, in which the specified point defines the progressive spectacle lens design, and then determining a value of each design parameter at the specified point by an interpolation of at least part of the predetermined values at the corner points and, optionally, of at least part of the predetermined values of the design parameter at the at least one additional point.
    Type: Grant
    Filed: January 22, 2010
    Date of Patent: May 31, 2016
    Assignee: Rodenstock GmbH
    Inventors: Helmut Altheimer, Wolfgang Becken, Gregor Esser, Dietmar Uttenweiler, Andrea Welk, Jochen Brosig, Christina Butz, Nadine Jung, Katrin Nicke, Ilka Schwarz, Robert Bichler, Martin Zimmermann, Werner Mueller, Hans Stetter

  • Progressive power ophthalmic lens
    Patent number: 4946270
    Abstract: A progressive power ophthalmic lens having at least one surface contributing to an increase in power from a distant portion via a progressive zone to a reading portion, radii of curvature of horizontal section curves of the at least one surface contributing to an increase in power and having horizontal planes as a function of the distance from the main meridian decrease in a front surface in the region of the main meridian in the distant portion and increase in the rear surface in the distant portion and decrease in the reading portion, and the course of change of the curvature .DELTA.rh-rh(x,y)-rh (0,y) reverses with increasing distance x from the main meridian.
