摘要： A computer-implemented method for determining biometric data of an eye and a corresponding method for manufacturing spectacle lenses taking into account the biometric data determined. The method includes: providing individual standard data of a user, the standard data including prescription data including a distance prescription and/or a near prescription of at least one eye of a user; and calculating individual additional data including at least one individual biometric parameter of the at least one eye of the user based on the individual standard data and using a statistical model describing a relation between the standard data and the additional data, wherein the statistical model has been derived using statistical analysis of a training data set with a plurality of reference data sets, each of the reference data sets including standard data and additional data associated with the standard data.

摘要： Method for determining a surface model for calculating a surface of an ophthalmic lens from a set of order parameters for the lens or from variables depending on the order parameters. The method includes providing a training data set having order parameter sets; providing a target value of a property of the lens for each of the order parameter sets; providing a surface model with parameters; and determining optimized values for the parameters using the provided target values by optimizing the values for the parameters by minimizing/maximizing a target function for the parameters. The target function for the parameters for each of the order parameter sets has a term which assumes a minimum/maximum when the provided target value coincides with the value of the same property of a lens which is calculatable with the surface model for given values of the parameters for the corresponding order parameter set.

摘要： In a method for creating a design of a prescription surface of a multifocal lens, in particular for a progressive spectacle lens, at first data and second data for describing at least one aberration of an eye of a proband for a first situation of use and a second situation of use, respectively, are obtained, and then a first set of parameters and a second set of parameters of a predetermined prescription surface equation are determined from the first and second data, wherein the prescription surface equation is assigned to a first reference point of the prescription surface for the first set of parameters, and is assigned to a second reference point of the prescription surface for the second set of parameters.

摘要： A computer-implemented method for calculating or assessing a spectacles lens for an eye of a spectacles wearer. The method includes (a) providing an association of at least one imaging property or aberration of a spectacle lens system with the vision of the spectacles wearer, or of an average spectacles wearer, when observing an object through the spectacles lens system; (b) determining or prescribing a target function for the spectacles lens to be calculated or assessed, in which the association from step (a) is to be evaluated; and (c) calculating or assessing the spectacles lens to be calculated or assessed by evaluating the target function, wherein the target function is evaluated at least once.

摘要： Adjustment of an eyeglass lens or a pair of eyeglasses by means of an individual brightness-dependent centering of an eyeglass lens. In particular, a method for adjusting an individual eyeglass lens for at least one eye of an eyeglass wearer. The method includes defining an individual usage situation which includes 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： 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.
