Progressive spectacle lens having a genuine short progression area
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 whi...

description | 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). |
