Patent number: 7673990Abstract: 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.Type: GrantFiled: October 22, 2004Date of Patent: March 9, 2010Assignee: Rodenstock GmbHInventors: Gregor Esser, Helmut Altheimer, Norbert Awrath, Jochen Brosig, Walter Haimerl, Winfried Nikolaus, Kerstin Schmid, Edda Wehner, Andrea Welk, Martin Zimmermann

Publication number: 20070109496Abstract: 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: ApplicationFiled: August 17, 2004Publication date: May 17, 2007Applicant: RODENSTOCK GMBHInventors: Helmut Altheimer, Gregor Esser, Andrea Welk, Leonhard Schmid, Martin Zimmermann, Kerstin Schmid, Norbert Awrath, Jochen Brosig, Winfried Nikolaus, Werner Muller, Ilka Schwarz

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

Publication number: 20040027678Abstract: The invention relates to a progressive spectacle lens comprising an area for looking over long distances and especially “to infinity” (distance-vision part); an area for looking over short distances and especially “reading distances” (near-vision part); and a progression area which is arranged between the distance-vision part and the near-vision part, and in which the power of the spectacle lens increases from the value in the far reference point in the distance-vision part to the value of the near reference point in the near-vision part, along a curve (main line) towards the nose. The invention is characterised in that the progression length is smaller than or equal to 12 mm, and the width of the distance-vision part in the horizontal section y=+7 mm, according to power and addition, is larger than the values provided in the table (I).Type: ApplicationFiled: September 9, 2003Publication date: February 12, 2004Inventors: Andrea Welk, Peter Baumbach, Walter Haimerl, Gregor Esser, Helmut Altheimer, Edda Wehner, Norbert Awrath, Martin Zimmermann, Winfried Nikolaus

Patent number: 5854669Abstract: The present description refers to a series of progressive lenses, wherein the lenses present a different surface power in the distance-vision part and/or a different increase of the surface power from the distance-vision part towards the near-vision part (termed addition Add hereinafter), and whereof eachcomprises a front surface having a continuously varying surface power which increases from the respective value BK ?dpt!, which is suitable for distance vision, at the point having the coordinates x=0 mm, y=8 mm in the lower region of the distance-vision part along a wound line (primary line), which coincides approximately with the primary line of view, with eyes dropped, towards a value suitable for near vision in the upper region of the near-vision part, which value is greater than the value of the surface power BK in the lower region of the distance-vision part by the value ADD ?dpt! of the addition, andhaving a surface, in particular the surface on the concave side, which has a spherical shape or an aspheType: GrantFiled: March 21, 1996Date of Patent: December 29, 1998Assignee: Optische Werke G.
