  • Error-tolerant progressive glass design
    Patent number: 7771047
    Abstract: A method of producing a progressive spectacle glass by defining an ordering value for the average use value in the far reference point of the progressive spectacle glass, calculating the progressive spectacle glass while taking into account a calculation value of the average use value in the far reference point, the calculation value having a negative desired refraction deviation between 0.03 dpt and 0.2 dpt with respect to the ordering value in the far reference point, and producing the calculated progressive spectacle glass.
    Type: Grant
    Filed: August 17, 2004
    Date of Patent: August 10, 2010
    Assignee: Rodenstock GmbH

  • Individual eyeglass lens
    Patent number: 7673990
    Abstract: An individual eyeglass lens in which the vertical distance from the near reference point to the far distance point amounts to max. 18 millimeters, the progressive length is max. 14 millimeters, the main progressive length is max. 10 millimeters and the increase in refractive index, starting from the effect of the eyeglass lens at the far reference point up to a point 2 millimeters below the centering point amounts to less than 10% of the addition. The progressive length corresponds essentially to the vertical distance between the far reference point and a point essentially on the main line at which, starting from the far reference point, the value of the effect of the eyeglass lens corresponding the first time essentially to the near value.
