Method for optimization of a progressive spectacle lens, including: defining a starting nominal astigmatism distribution for the spectacle lens; determining a transformed nominal astigmatism distribution and optimizing the spectacle lens on the basis of the transformed nominal astigmatism distribution, wherein the determination of a transformed nominal astigmatism distribution comprises multiplication of the maximum temporal nominal astigmatism of the starting nominal astigmatism distribution by a factor k as a result of which a modified maximum temporal astigmatism is obtained, wherein k is a function of a prescription value, and/or at least of one parameter of the spectacle lens or of the arrangement thereof in front of the eyes, and transformation of the starting nominal astigmatism distribution on the basis of the modified maximum temporal astigmatism.

Prescription-dependent and individualization-dependent modification of the temporal peripheral nominal astigmatism and adaptation of the object distance function to changed object distances for near and far vision

A method and device for calculating design parameters of a design of a progressive spectacle lens on the basis of a predetermined design polygon. The design parameters are calculated by specifying a point within the design polygon, in which the specified point defines the progressive spectacle lens design, and then determining a value of each design parameter at the specified point by an interpolation of at least part of the predetermined values at the corner points and, optionally, of at least part of the predetermined values of the design parameter at the at least one additional point.

Controlling designs using a polygonal design

Method for optimization of a progressive spectacle lens, which method comprises: defining a starting nominal astigmatism distribution for the spectacle lens; determining a transformed nominal astigmatism distribution and optimizing the spectacle lens on the basis of the transformed nominal astigmatism distribution, wherein the determination of a transformed nominal astigmatism distribution comprises multiplication of the maximum temporal nominal astigmatism of the starting nominal astigmatism distribution by a factor k as a result of which a modified maximum temporal astigmatism is obtained, wherein k is a function of a prescription value, and/or at least of one parameter of the spectacle lens or of the arrangement thereof in front of the eyes, and transformation of the starting nominal astigmatism distribution on the basis of the modified maximum temporal astigmatism.

Prescription-dependent and individualization-dependent modification of the temporal peripheral nominal astigmatism and adaption of the object distance function to changed object distances for near and/or far vision

A method, a system and a computer program product are provide for optimizing a spectacle lens for a wearer with a selectable quality grade. In particular, a set of individual parameters is determined for the wearer and a desired quality grade is identified. Depending the identified quality grade, the set of individual parameters is adapted and a surface of the spectacle lens is calculated based on the adapted set of individual parameters.

Method and system for optimizing a spectacle lens based on individual parameters of a wearer

A fast and efficient method for calculating or producing a spectacle lens design, as well as a method for manufacturing a spectacle lens according to the thus calculated spectacle lens design. Furthermore, a corresponding device is provided for manufacturing a spectacle lens, as well as corresponding computer program products and storage media.

Rescaling of the target astigmatism for other additions

A spectacle lens with an object-sided front face and an eye-sided rear face, wherein at last the rear face comprises a viewing region that contributes to the optical effect of the spectacle lens and a carrier rim region that at least partially surrounds the viewing region and that does not significantly contribute to the optical effect of the spectacle lens. The rear face of the spectacle lens in the carrier rim zone is constructed substantially from a cosmetic viewpoint without consideration of the optical image-forming properties. A method for producing this spectacle lens is also provided.

Glasses lens comprising a carrying edge

A method of producing a progressive spectacle glass by defining an ordering value for the average use value in the far reference point of the progressive spectacle glass, calculating the progressive spectacle glass while taking into account a calculation value of the average use value in the far reference point, the calculation value having a negative desired refraction deviation between 0.03 dpt and 0.2 dpt with respect to the ordering value in the far reference point, and producing the calculated progressive spectacle glass.

Error-tolerant progressive glass design

An individual eyeglass lens in which the vertical distance from the near reference point to the far distance point amounts to max. 18 millimeters, the progressive length is max. 14 millimeters, the main progressive length is max. 10 millimeters and the increase in refractive index, starting from the effect of the eyeglass lens at the far reference point up to a point 2 millimeters below the centering point amounts to less than 10% of the addition. The progressive length corresponds essentially to the vertical distance between the far reference point and a point essentially on the main line at which, starting from the far reference point, the value of the effect of the eyeglass lens corresponding the first time essentially to the near value.

A progressive power spectacle lens in which a progressive length is less than or equal to 12 mm and width of the distance portion in a horizontally meridian y&equals;&plus;7 mm in dependence on power and addition power is larger than the values given in the following Table:

Progressive spectacle lens having a genuine short progression area

Described is a spectacle lens comprising a region (distance portion) designed for viewing at large distances and in particular &ldquo;to infinity&rdquo;, a region (near portion) designed for viewing at short distances and in particular &ldquo;reading distances&rdquo;, 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 &ldquo;right-hand side spectacle lens&rdquo; are located at 95&deg;&plusmn;10&deg; (according to TABO) and at 280&deg;&plusmn;10&deg;, and on a &ldquo;left-hand side spectacle lens&rdquo; at 85&deg;&plusmn;10&deg; and 260&deg;&plusmn;10&deg;; and two local maxima occur which on both a &ldquo;right-hand side spectacle lens&rdquo; and also a &ldquo;left-hand-side spectacle lens&rdquo; are located at 215&deg;&plusmn;10&deg; and 335&deg;&plusmn;10&deg;.
