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 |
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 |

20140340637 | BRIGHTNESS-DEPENDENT ADJUSTMENT OF A SPECTACLE LENS - 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. | 11-20-2014 |
