Progressive spectacle lens with true short progression

Progressive spectacle lens with - one to look into greater distances and in particular designed "into infinity" range (distance portion), - one to look into shorter distances and in particular "reading distances" designed region (near portion), and - arranged between the distance portion and the near portion progression zone, in which the effect of the spectacle lens of the value in the located in the distance portion the distance reference point to the value of the located in the near portion near reference point increases along a towards the nose sinuous curve (principal line), characterized in that the length of progression is less than or equal to 12 mm and the distance portion width in the horizontal section y = + 7 mm, depending on the recipe value of the power and addition greater than those given in the following table: Sph = -6.0 diopters -2.5 diopters 0.5 diopters 3.0 diopters 5.0 diopters Addition = 1.0 47 mm 55 mm 60 mm 60 mm 60 mm Addition = 2.0 34 mm 36 mm 34 mm 29 mm 35 mm Addition = 3.0 26 mm 27 mm 25 mm 22 mm 23 mm and the maximum rise of the magnification in the horizontal section y ...
