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 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.
