    摘要: A spectacle lens comprises a region (distance portion) designed for viewing at greater distances, in particular, to infinity; a region (near portion) designed for viewing at short distances and, in particular, “reading distances”; and a progression zone located between the distance portion and the near portion, in which the power of the spectacle lens increases from a value at 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. It is one of the characteristics of the invention that for minimizing the change of imaging properties with horizontal movements of the gaze along a curve described by the points of penetration of the principal rays through the front surface, these principal rays passing through a point having the coordinates (x−dx, y, s) at the beginning of the movement and a point having the coordinates (x +dx, y, s) at the end of the movement, at s=−40 mm and dx=10 mm particular conditions apply.

    摘要: A spectacle lens comprises a region (distance portion) designed for viewing at large distances and in particular “to infinity”; a region (near portion) designed for viewing at short distances and in particular “reading distances”; and a progressive zone disposed between the distance portion and the near portion, in which a power of the spectacle lens increases from a value at a distance reference point located in the distance portion to a value at a near reference point located in the near portion along a curve (principal line) veering towards a nose. The invention is distinct in that, for minimizing a change of binocular imaging properties with horizontal movements of glance, a lift (difference between a maximum and a minimum value occurring during a movement) of binocular imaging properties when a moving object is being followed, is smaller than a physiologically pre-determined limiting amount.

    摘要: Described is a spectacle lens comprising a region (distance portion) designed for viewing at large distances and in particular “to infinity”, a region (near portion) designed for viewing at short distances and in particular “reading distances”, and a progressive zone disposed between the distance portion and the near portion, in which the power of the spectacle lens increases from a value at a distance reference point located in the distance portion to a value at the near reference point located in the near portion along a curve (principal line) veering towards the nose. The invention is distinct in that the astigmatic deviation, i.e. the difference between the prescribed and the actual astigmatism along circles having a center lying 4 mm below the centration point and having a diameter of 10 to 40 mm satisfies the following conditions: two local minima occur which on a “right-hand side spectacle lens” are located at 95°±10° (according to TABO) and at 280°±10°, and on a “left-hand side spectacle lens” at 85°±10° and 260°±10°; and two local maxima occur which on both a “right-hand side spectacle lens” and also a “left-hand-side spectacle lens” are located at 215°±10° and 335°±10°.

    摘要: A method for representing and optimizing a double-progressive spectacle lens is characterized by the following steps: selecting a suitable coordinate system K2 for the representation of a back surface; selecting a suitable grid G for the representation of a spline of the back surface of a starting lens to be optimized in a coordinate system K2; assigning sagittal height data of the back surface to a spline (back surface spline); defining a position of a center of rotation of an eye; computing principal rays from the center of rotation of the eye through the starting lens at grid points of G; computing a length of a distance between points of penetration of a thus computed principal ray through a front surface and the back surface (oblique thickness); assigning data of the oblique thickness (thickness spline) to a spline; selecting a set of assessment positions at which an optical quality is computed for a target function; suitably selecting particular optical and geometrical stipulations which ideally should be satisfied at the assessment positions; defining the target function as a deviation of the quality of an actual spectacle lens from ideal values; starting the optimization; evaluating at each one of optimization steps the optical properties in a wearing position at the assessment points by means of surface properties to be computed and actual principal ray data; ending the optimization when the target function is below a particular value, or after a specifiable maximum number of optimization steps.
