    • The invention relates to a method for representing and optimising a double-progressive spectacle lens. Said method is characterised by the following steps: a suitable co-ordinates system K2 is selected for representing the rear surface; a suitable grid G is selected for representing the spline of the rear surface of a starting lens to be optimised in K2; the sagittal data of the rear surface (rear surface spline) is applied to a spline; the position of the centre of rotation of the eye is defined; the main beams from the centre of rotation of the eye through the starting lens to the grid points of G are examined; the length of the distance between the piercing points of the main beam examined, through the front surfaces and the rear surfaces (diagonal thickness) is calculated; the data of the diagonal thickness is applied to a spline (thickness spline); a set of evaluation points is selected, by which means the optical quality is calculated for the target function; certain optical and geometric standards which ideally correspond to the evaluation points are suitably selected; the target function is defined as a deviation from the quality of current spectacle lenses in terms of said ideal values; the optimisation is initiated; at each optimisation step, the optical properties in the position of use at the evaluation points are evaluated by means of the surface properties to be calculated and current main beam data; the optimisation is completed when the target function is below a certain value, or at the end of a pre-definable maximum number of optimisation steps.

    • Disclosed is a method for demonstrating the influence of a specific spectacle frame and the optical glasses inserted into said spectacle frame on the appearance of the person wearing a pair of glasses as perceived by another person (a virtual observer). The invention comprises the following features: an image of the face of a person wearing glasses is provided in such a way that the image can be processed in a computer, the arrangement of the respective spectacle frame in front of the eyes is determined; the image of the face is projected onto a plane by means of ray tracing through the point of rotation of the eye of the (virtual) observer, whereby a 2-D image of the face is produced on said plane; during calculation of the course of progression of the main beam disposed inside the rings of the glasses of the spectacle frame or the edges of the spectacle glasses, the optical effect of the area of the spectacle glass respectively (virtually) inserted into the respective glass ring, through which the main beam passes, and the arrangement thereof in front of the eye is taken into account in such a way that an observer of the 2-D image of the face thus produced wearing said glasses, is able to judge the distortion of the eye part of the face by the spectacle glasses and therefore evaluate the quality of the spectacle glasses.
