88. | Device for determining centring parameters for the adjustment of spectacles
Abstract A device for determining centering parameters for the adjustment of spectacles includes a camera support partially surrounding an inner area that is open at the top, bottom and to the rear; and at least three cameras arranged between two free ends of the camera support and pointing towards the inner area, the camera support having an illumination system in order to illuminate the inner area. The illumination system is designed to light the inner area such that the light intensity, at least at each point in a region extending over a height of 20 cm and a central angle of 180 degrees of an outer cylinder surface having a diameter of 20 cm and formed in the inner area, deviates by a maximum +50% and −30% from a predefined desired value.

90. | COMPUTER IMPLEMENTED METHOD OF DETERMINING A BASE CURVE FOR A SPECTACLE LENS AND METHOD OF MANUFACTURING A SPECTACLE LENS
Abstract A computer-implemented method of determining a base curve value representing a base curve for a front surface of a spectacle lens is disclosed. The method includes receiving individual prescription data and determining the base curve value for the front surface of the spectacle lens based on the prescription data. In particular, the base curve value is calculated from the received prescription data based on a functional relationship between one or more values included in the prescription data and the base curve value.

91. | Adjustable progressive lens and design method
Abstract An adjustable spectacle lens has a first lens element and a second lens element arranged one behind the other along an optical axis of the lens. The first and second lens element are configured to vary their combined optical properties when moved relative to each other in a direction transverse to the optical axis. The adjustable lens element is an adjustable progressive lens element. The first and second lens element are configured to vary at least one of a size and a power of the near, the distance, and the intermediate portion relative to each other, when the first lens element and the second lens element are moved relative to each other in the direction transverse to the optical axis. The first and second lens elements can be configured to conjointly provide a near, a distance and an intermediate portion that can be changed depending on the visual task. IPC Classes ?

93. | METHOD FOR MANUFACTURING A SPECTACLE LENS ACCORDING TO AT LEAST ONE DATA SET OF EDGING DATA
Abstract A method for manufacturing a spectacle lens according to at least one data set of edging data and a computer program product with instructions for performing the method are disclosed. A spectacle lens blank, semifinished spectacle lens product, or a finished spectacle lens product is inspected for defects and compared to a data set to determine if it can be manufactured into an edged finished spectacle lens that fits into a specific spectacle frame such that the defect is not present in the edged finished spectacle lens.

94. | PROGRESSIVE SPECTACLE LENS HAVING A VARIABLE REFRACTIVE INDEX AND METHOD FOR THE DESIGN AND PRODUCTION THEREOF
Abstract The invention relates to a progressive spectacle lens, the progressive spectacle lens having a front face and a rear face and a uniform substrate with a locally varying refractive index, the front face and/or the rear face of the substrate being formed as a free-form surface and carrying only functional coatings, if any. The invention is characterized in that (a) the refractive index varies only in a first spatial dimension and in a second spatial dimension and is constant in a third spatial dimension, a distribution of the refractive index in the first spatial dimension and the second spatial dimension being neither point-symmetrical nor axis symmetrical, or (b) the refractive index varies in a first spatial dimension and in a second spatial dimension and in a third spatial dimension, a distribution of the refractive index in the first spatial dimension and the second spatial dimension in all planes perpendicular to the third spatial dimension being neither point-symmetrical nor axis symmetrical, or (c) the refractive index varies in a first spatial dimension and in a second spatial dimension and in a third spatial dimension, a distribution of the refractive index not being point-symmetrical or axis symmetrical at all. The invention further relates to a method for the design and production of such a progressive spectacle lens. IPC Classes ?

96. | PROGRESSIVE SPECTACLE LENS WITH REGIONALLY VARYING REFRACTIVE INDEX AND METHOD FOR THE DESIGN OF SAME
Abstract The invention relates to a progressive spectacle lens, comprising a substrate which has a front face and a rear face and consists of a material with a regionally varying refractive index, wherein the front face and/or the rear face has/have a free-form surface geometry. The progressive spectacle lens complies with the following optical requirements: (1) a prescribed dioptric power in the distance reference point within the permissible limit deviations in accordance with EN ISO 8980-2:2004 and a prescribed dioptric power in the near reference point within the permissible limit deviations in accordance with EN ISO 8980-2:2004, (2) a monotonically steady increase in the dioptric power between the distance reference point and near reference point along a principal line of vision and (3) a progression channel. The progressive spectacle lens according to the invention is characterized in that the free-form surface geometry of the front face and/or rear face of the progressive spectacle lens and the regional variation of the refractive index are matched such that a comparative progressive spectacle lens of the same geometry but based on a substrate of a material having a refractive index that does not vary regionally fails to comply with at least one of the optical requirements (1) to (3).
