| 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 |
| 20100309428 | Flexible Progressive Lens Optimizer - A method is provided for calculating an individual spectacle lens design for a progressive spectacle lens exhibiting an individual vertical position of the distance and/or the near reference points, which can be variably adjusted. A starting design exhibiting a predefined vertical position of the distance and/or the near reference points is determined; the individual spectacle lens design is calculated having the desired, individual vertical position of the distance and/or near reference points. The calculation of the individual spectacle lens design includes calculating the target value S | 12-09-2010 |
| 20110007269 | METHOD AND APPARATUS OF MEASURING OPTICAL PARAMETERS OF A PERSON USING A LIGHT FIELD - A method and apparatus provided to measure optical parameters of a person wearing spectacles. One or more fixation targets are provided to generate a flat extensive light field that can align the direction of sight of the person when the person looks at the light filed. Image recording devices are provided to generate image data of subareas of the person's head and a data processing unit can determine the optical parameters based on the generated image data. | 01-13-2011 |
| 20110051082 | METHOD FOR CALCULATING AND OPTIMIZING A PAIR OF EYEGLASSES IN CONSIDERATION OF BINOCULAR PROPERTIES - A method and apparatus for producing a first spectacle lens of a pair of spectacle lenses to be used with a second spectacle lens for a specific situation of wear, in which optical parameters for the spectacle lens are calculated to minimize the value of a target function that corresponds to the pair of spectacle lenses. The target function is the sum of a first monocular function, with a weighting factor, that depends on the values of a first monocular optical property at a plurality of monocular evaluation points, a the binocular function, with a weighting factor, that depends on the values of a second monocular optical property at the plurality of pairs of binocular evaluation points, and a remainder term. | 03-03-2011 |
| 20110208493 | RESCALING OF THE TARGET ASTIGMATISM FOR OTHER ADDITIONS - 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. | 08-25-2011 |
