| 20090021693 | Device and Method for Determining Optical Parameters - The invention relates to a device ( | 01-22-2009 |
| 20100145489 | METHOD FOR OPTIMIZING A SPECTACLE LENS - The invention relates to a method, a computer program product and a system for designing or producing a spectacle lens for a spectacle wearer. Said method consists of the following steps: individual user data or application data of the spectacle wearer is obtained; the design concept for the spectacle lens having a plurality of evaluation points is determined; a main beam path through the plurality of evaluation points is determined; a local wavefront is specified for each of the main beams in the surroundings of the respective main beam; optical properties of the spectacle lens are determined on the evaluation points by determining an influence of the spectacle lens on the local wavefronts in the surroundings of the respective evaluation point; and the design concept is evaluated in accordance with the determined optical properties and the individual user data. | 06-10-2010 |
| 20100157242 | Method for Calculating a Spectacle Lens Having a Variable Position of the Reference Points - The invention relates to a method for producing a progressive spectacle lens and to a corresponding apparatus, a computer program product, a storage medium and to the use of a progressive spectacle lens. The invention also relates to a method for producing a progressive spectacle lens for correcting defective vision of a spectacle wearer, comprising the following steps: the vertical and/or the horizontal spatial position of a distance reference point and/or a near reference point is specified or determined in accordance with individual data of the spectacle wearer; the spectacle lens is optimized or calculated such that the required dioptric effect of the spectacle lens is obtained in the individually determined distance reference point and/or the near reference point. | 06-24-2010 |
| 20100171922 | Spectacle Glass and Spectacle Lens for Data Reflection - The invention relates particularly to a spectacle lens having a first and a second surface, wherein at least the first surface of the spectacle lens has a major portion zone and at least one prism zone. The major portion zone of the first surface, together with the opposing second surface of the spectacle lens, forms a major portion of the spectacle lens, which is designed for vision in at least a predetermined distance. The prism zone of the first surface, together with the opposing second surface of the spectacle lens, forms a prism portion, which is designed and arranged such that an optical image of a display is formed at a predetermined virtual distance in front of the eyes of the spectacle wearer. The invention further relates to spectacles, which comprise the spectacle lens, and to a method and apparatuses for calculating or optimizing and producing the spectacle lens. | 07-08-2010 |
| 20100198817 | Method for Checking and/or Determining User Data, A Computer Program Product, and an Apparatus - The present invention relates in summary to a method for checking and/or determining user data of a spectacle lens user comprising the steps of:—providing (S | 08-05-2010 |
| 20120008090 | CONTROLLING DESIGNS USING A POLYGONAL DESIGN - 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. | 01-12-2012 |
