  • Publication number: 20190391411
    Abstract: A product includes a progressive power spectacle lens or a representation, stored on a data storage medium, of the progressive power spectacle lens. The progressive power spectacle lens has a front surface and a back surface and a spatially varying refractive index, wherein the front surface and/or the back surface is embodied as a progressive surface. The front surface is formed as a free-form surface in such a way that the maximum of the absolute value of the mean curvature of the front surface lies in the intermediate corridor and/or the back surface is formed as a free-form surface in such a way that the minimum of the absolute value of the mean curvature of the back surface lies in the intermediate corridor. Further, a computer-implemented method for planning a progressive power spectacle lens with a spatially varying refractive index and a progressive surface is disclosed.

  • Patent number: 9995938
    Abstract: A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens can be constructed with several shells including an outer shell and an inner shell which is joined to the outer shell, wherein a curved channel shell, which includes a curved first reflecting surface and a curved second reflecting surface, is arranged between the outer and inner shell. The light guiding channel includes at least one section of the channel shell and the two reflecting surfaces on which the light bundles are reflected for guiding from the coupling-in section to the coupling-out section.

    Abstract: The invention relates to an arrangement with a spectacle lens having a changeable optical effect and with an effect-setting apparatus for setting the optical effect of the spectacle lens on the basis of intended-setting data. A memory apparatus stores first intended-setting data for setting a first predetermined optical intended effect, which was established from a first refraction measurement on an eye of a spectacles wearer for whom the spectacle lens is destined, and for storing second intended-setting data for setting a second predetermined optical intended effect, which was established from a second refraction measurement on the eye, and also a supply apparatus for supplying the first intended-setting data or the second intended-setting data to the effect-setting apparatus.
