摘要： 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).

摘要： The invention relates to a method for producing eyeglasses having individual progressive eyeglass lenses involving the following steps: Selecting an eyeglass frame; measuring the shape of the lens rings in the x and y directions with a precision better than ?0.5 mm (data set 1); measuring the points of emergence of the visual rays through the plane of the lens rings for at least two provided distances of the progressive eyeglass lenses with a precision better than ?1 mm (data set 2); selecting and positioning, with regard to the lens rings, a spherical or aspherical surface with regard to the prescription data and using data sets 1 and 2 (data set 3); calculating and positioning the progressive surface in relation to the selected surface while minimizing the critical thickness of the eyeglass lens and using data sets 1 to 3 (data set 4); finishing the progressive surfaces and edging the eyeglass lenses from a non-edged semi-finished product, which is finished on one side, using data sets 1 to 4.

摘要： The invention relates to a method for optimizing a progressive spectacle lens. The invention is characterized by the following steps: selecting a predetermined progressive addition lens with a given object distance function A1(x,y), selecting an object distance function A2 (x=xo,y) along the main line of vision of the predetermined progressive addition lens for a spectacle lens to be derived therefrom; finding representation U:y→y' along the main line of vision in such a way that the corresponding value y' can be calculated for every value of y, wherein A1 (x=xo, y) = A2 (x=xo, y'), calculating the theoretical values S(x,y) wherein S(x,y')=S(x,U(y)).

摘要： The invention relates to a progressive spectacle lens comprising two non-spherical surfaces, more particularly two progressive surfaces, which contribute to the enhancement of the effectiveness (addition add) of the long distance vision part to the reading distance part. The invention is characterized in that the sagittas zi = zi (x, y) of at least one (i) progressive surface (i=1,2) are selected in such a way that the sagittas (z) of the respective surface have predetermined values in the edge of the glass spectacles defined by yi = fi1 (x) for y = 0 or. Yi = fi2 (x) for y

摘要： Die vorliegende Erfindung betrifft ein Brillenglas zur Korrektur der Fehlsichtigkeit des Auges eines Brillenträgers und eine Serie von Brillengläsern. Das Brillenglas weist eine erste Wirkung P_A in einem Bezugspunkt des Brillenglases auf, wobei:
die Fehlsichtigkeit durch zumindest einen ersten, mittels einer Messvorrichtung der ersten Art zur Messung der Fehlsichtigkeit erhaltenen und aus mehreren Komponenten bestehenden Messwert P_A1, und zumindest einen zweiten, mittels einer Messvorrichtung der zweiten Art zur Messung der Fehlsichtigkeit erhaltenen und aus mehreren Komponenten bestehenden Messwert P_A2 charakterisiert wird, wobei sich der erste Messwert P_A1 und der zweite Messwert P_A2 in zumindest einer Komponente X unterscheiden;
die Komponente X der im Bezugspunkt des Brillenglases vorhandenen ersten Wirkung P_A näher an der Komponente X desjenigen Messwerts unter den Messwerten P_A1 oder P_A2 des Brillenglases liegt, welcher von der Messvorrichtung mit der geringeren Ungenauigkeit bei der Messung der Komponente X erhalten wird, und wobei
die Komponenten der Messwerte P_A1 und P_A2 Komponenten einer Wellenfrontdarstellung der Fehlsichtigkeit, deren Linearkombination oder daraus abgeleitete Größen sind.
Ferner betrifft die vorliegende Erfindung Verfahren und Vorrichtungen zum Herstellen des Brillenglases und der Serie von Brillengläsern.

摘要： The present invention relates to an improvement of the adjustment of an eyeglass lens or a pair of eyeglasses by means of an individual brightness-dependent centring of an eyeglass lens. In particular, the invention offers a method for adjusting an individual eyeglass lens for at least one eye of an eyeglass wearer, comprising: defining an individual usage situation which comprises at least one target brightness value for the light to be captured by the at least one eye; determining a position of the pupil in at least one direction of view of the at least one eye which occurs or is expected at the at least one target brightness value; determining a reference point of the eyeglass lens, in which the eyeglass lens effects a required correction of individual refraction data for the at least one direction of view; on the basis of the determined individual value of the pupil position, providing and arranging the eyeglass lens in such a manner that the at least one reference point of the eyeglass lens is arranged in front of the at least one eye of the eyeglass wearer.

摘要： The invention relates to a computer-implemented method for determining a diffraction grating for colour fringe compensation of a refractive optical element, which method comprises recording data of the refractive optical element, and calculating the diffraction grating on the basis of the recorded data of the refractive optical element, in such a way that the grating lines of the diffraction grating follow the lines of constant thickness of the refractive optical element or the lines of the constant amount of the prism of the refractive optical element or are perpendicular to the local base setting of the prism of the refractive optical element. The invention further relates to corresponding methods and devices for producing an optical element with at least one diffraction grating that has been determined by this method.
