    摘要: A progressive spectacle lens includes a substrate which has a front face and a rear face and is made from 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 has a free-form surface geometry of the front face and/or rear face.

    摘要: Spectacles include a spectacles lens having a carrier lens with a carrier lens front surface and/or a carrier lens rear surface, and having a front surface lens segment arranged on the carrier lens front surface and/or a rear surface lens segment arranged on the carrier lens rear surface, which are moveably guided on the carrier lens front surface and/or the rear surface lens segment, respectively. Further, the spectacles include a front/rear surface lens segment drive for moving the front/rear surface lens segment on the carrier lens front/rear surface, respectively; an eye position detection device for detecting the position of an eye of a wearer wearing the spectacles; and a drive control device for controlling the front and/or rear surface lens segment drive in accordance with the position of the eye detected by the eye position detection device.

    摘要: A progressive addition lens contains a plurality of microlenses for providing simultaneous myopic defocus. The microlenses are superimposed on a power variation surface of the lens, which includes a designated distance portion in the upper section of the lens adapted for distance vision and a fitting cross; a designated near portion located in the lower section of the lens, the near portion including a near reference point having a near dioptric power adapted for near vision; and a designated intermediate corridor extending between the designated distance portion and near portions. Microlenses are excluded from all areas of the surface located below a notional line extending from nasal to temporal limits of the lens at a vertical coordinate above the near reference point where the vertical coordinate lies at a distance above the near reference point with the distance being in a range between 1.5 mm and 3 mm.

    摘要: A progressive spectacle lens has a front surface, a rear surface, and a spatially varying refractive index. The progressive spectacle lens can have: (a) a refractive index that changes only in a first and second spatial dimension and is constant in a third spatial dimension, and the distribution of the refractive index in the first spatial dimension and the second spatial dimension is neither punctually nor axially symmetric; (b) a refractive index that changes in a first, a second, and third spatial dimension, and the distribution of the refractive index in the first spatial dimension and the second spatial dimension is neither punctually nor axially symmetric on all planes perpendicular to the third spatial dimension; or (c) a refractive index that changes in a first, second, and third spatial dimension, and the distribution of the refractive index is not punctually or axially symmetric at all.

    摘要: A progressive spectacle lens has 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 is formed as a free-form surface and carries only functional coatings, if any. The refractive index varies (a) 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 being neither point-symmetrical nor axis symmetrical, or (b) in a first spatial dimension and in a second spatial dimension and in a third spatial dimension, a distribution of the refractive index being neither point-symmetrical nor axis symmetrical, or (c) 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.
