摘要:
The invention relates to a spectacle lens device comprising at least one electrically adaptive area, wherein optical properties of the spectacle lens device can be controlled in an electric manner. The spectacle lens device is configured in such a manner that the optical properties of a predetermined or predeterminable control area can be controlled in an electrical manner which is essentially independent from the optical properties in a surrounding area. The invention also relates to the control area and to the surrounding area, respectively, about a partial area of the electrically adaptive area. The control area and the surrounding area do not a common area. The invention further relates to a pair of spectacles comprising a spectacle lens device, to the use of the inventive spectacle lens device and also to a method for operating an electrically adaptive area.

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.
摘要:
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.

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. Method for optimization of a progressive spectacle lens, which method comprises: defining a starting object distance function; determining object distance data, wherein these comprise an object distance at a predetermined point on the main line of sight; modifying the starting object distance function in accordance with the object distance data; optimizing the spectacle lens, wherein the transformed object distance function is taken into account, wherein the modification of the starting object distance function comprises superposition with a correction function, which has a variable parameter that is determined, in accordance with the object distance data, in such a way that the value of the modified starting object distance function at the predetermined point is equal to the reciprocal value of the determined nominal object distance for this point, wherein the object distance function is defined as the reciprocal object distance along the main line of sight.
摘要:
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.
