摘要:
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.

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.

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.

摘要:
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.

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.
