A computer-implemented method for calculating a digital twin of a spectacle lens is provided to use the digital twin for a manufacture of the spectacle lens. The digital twin has a predefined power distribution and contains a layer stack with a plurality of individual layers, each layer having a non-uniform layer thickness with a spatial variation and a uniform refractive index. The method includes determining the spatial variation of the layer thicknesses of the individual layers to achieve the predefined power distribution by a spatial control of optical path lengths.

A spectacle lens for a display device which can be placed on the head of a user and generate an image has a front and a rear, an injection section and a deflection section spaced from the injection section, an exit section in the rear and a light-guiding channel which guides light beams of pixels of the generated image, which are injected into the spectacle lens via the injection section, in the spectacle lens to the deflection section, by which they are deflected towards the exit section and then coupled out of the spectacle lens through the exit section. The spectacle lens is in the form of a progressive lens having a distance vision region and a near vision region, and the exit section, as viewed from above onto the rear of the spectacle lens, lies outside the distance vision region and outside the near vision region.

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.

A projection optical unit for microlithography includes a plurality of mirrors and has a numerical aperture having a value larger than 0.5. The plurality of mirrors includes at least three grazing incidence mirrors, which deflect a chief ray of a central object field point with an angle of incidence of greater than 45&#xb0;. Different polarized light beams passing the projection optical unit are rotated in their polarization direction by different angles of rotation. The projection optical unit includes first and second groups of mirrors. The second group of mirrors includes the final two mirrors of the plurality of mirrors at the image side. A linear portion in the pupil dependence of the total geometrical polarization rotation of the projection optical unit is less than 20% of a linear portion in the pupil dependence of the geometrical polarization rotation of the second group of mirrors.

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.
