摘要： A method for optimizing an atoroidal surface of an optical lens, in particular a spectacle lens, having at least one plane of symmetry is characterized by a combination of the following features: dividing the atoroidal surface having at least one plane of symmetry into at least two regions separated by the at least one plane of symmetry; representing one of the separate regions (represented region) of this surface by a set of coefficients of B spline functions; computing sagittal heights of the represented region by B spline interpolation; computing sagittal heights in at least one other region by mirroring coefficients or coordinates at the at least one plane of symmetry; and optimizing the atoroidal surface only by varying the set of B spline coefficients of the represented region.

摘要： A method is provided for demonstrating an effect of a particular spectacle frame and of optical lenses fitted into this spectacle frame on the appearance of a spectacles wearer as it would be perceived by another person (virtual observer). An image of a face of the spectacles wearer is prepared in such manner that the image can be processes in a computer. An arrangement of the respective spectacle frame in front of the eyes is determined. The image of the face is projected onto a plane by a computation (ray-tracing) of principal rays passing through a center of rotation of an eye of the (virtual) observer to produce a planar image of the face in this plane. Taking into account an optical power of a region, through which a principal ray passes, of each spectacle lens (virtually) fitted in the respective lens rim, and it arrangement in front of the eye, the paths of prinipcal rays which lie within lens rims of the spectacle frame or edges of the spectacle lenses are computed so that an observer of the thus-produced planar image of the face with “worn” spectacles can assess a distortion of the eyes portion of the face by the spectacle lenses and therewith a quality of the spectacle lenses.

摘要： A method for computing a spectacle lens, which includes a region (distance portion) designed for viewing at large distances and in particular “to infinity”, a region (near portion) designed for viewing at short distances and in particular “reading distances,” and a progressive zone disposed between the distance portion and the near portion, in which the power of the spectacle lens increases, from a value at a distance reference point located in the distance portion to a value at the near reference point located in the near portion along a curve (principal line) veering towards the nose, by an amount designated as addition power. The method includes the steps of stipulating as initial parameters a course of a projection x0(y) of the principal line on an x,y plane, and also properties of the spectacle lens along the principal line whilst taking into account spherical, cylindrical, and possibly also prismatic prescription values and the addition power, as well as an interpupillary distance, and computing with these stipulations at least one strip of second order on a progressive surface of the spectacle lens, stipulating an object-distance function Al(y) which describes a change of object distance with a movement, in particular a lowering, of a glance, determining on each horizontal meridian of the progressive spectacle lens a point of penetration of a principal ray through the progressive surface, for which point a distance of a point of intersection of this principal ray with a plane which bisects the interpupillary distance is equal to the object distance given by the object-distance function Al(y), computing for the entirety of these points of penetration lying on the principal viewing line a course of the projection x′0(y) on the x,y plane, equating the course x0(y) to x′0(y) and checking the coincidence, subsequently iteratively repeating the steps a. to e. until the projection x0(y) of the principal line is equal (within given limits) to the course of the principal viewing line projection x′0(y) used for the computation of the respective surface.

摘要： A workplace screen lens, having a workplace screen lens optimized at the middle of the lens for the middle viewing distances of approximately 60 centimeters to approximately 90 centimeters, and the progressive channel at the middle of the lens is at least 4 millimeters wide. The effect increases from the middle of the lens toward the bottom with the vertical coordinate y equal to approximately 0, reaching a near vision zone with an essentially constant effect at y equal to approximately −12 millimeters. The progressive channel has a width of least 15 millimeters in the near vision zone, preferably at the near-reference point, the effect decreases from the middle of the lens up to y equal to approximately +10 millimeters to approximately +12 millimeters above the middle of the lens. The progressive length amounts to approximately 20 millimeters to approximately 25 millimeters, the main progressive length is between approximately 7 millimeters and approximately 12 millimeters, and the minimum width of the progressive channel amounts to at least 4 millimeters.

摘要： A spectacle lens comprises a region (distance portion) designed for viewing at large distances and in particular “to infinity”; a region (near portion) designed for viewing at short distances and in particular “reading distances”; and a progressive zone disposed between the distance portion and the near portion, in which the power of the spectacle lens increases from a value at a distance reference point located in the distance portion to a value at the near reference point located in the near portion along a curve (principal line) veering towards the nose. The invention is distinguished by a combination of the following features: a change of magnification with a direction of sight is small; the magnification increases radially, starting from the distance reference point; the difference between the magnifications at the distance and near reference points is small.
