摘要： The description relates to optical glasses with a refractive index varying as a function of at least one co-ordinate, produced using a basic material with a constant refractive index by ion exchange. Greater index gradients than those obtainable in the present state of the art are obtained by means of special compositions and appropriate ion exchange baths. In addition, the stability of the glasses is increased.

摘要： The description relates to a set of progressive spectacle lenses in which the individual lenses in the set have a different surface power in the distance vision section and/or a different increase in the surface power from the distance to the close vision sections (Addition Add), each of which has a frontal surface with a continuously varying surface power which increases from the value BK (dpt) suitable for distance vision at the point having coordinates x = 0 mm, y = 8 mm in the lower part of the distance vision section along a bowed line (main line), which coincides with the main line of sight when the regard is lowered, to a value suitable for close vision in the upper region of the close vision section which is higher than the surface power BK in the lower region of the distance vision section by the value Add (dpt) of the addition, and the surface on the side towards the eye may be spherical or aspherical. The invention is distinguished in that, for the height y of the line at which the surface astigmatism is 0.5 dpt and which forms the lower border of the region of the distance vision section suitable for clear vision, y = f(Add,BK) = b(BK) + a/Add, b(BK) = a0 + a1*BK + a2*BK2 applies on both sides at a distance of 25 mm from the main line and, for the coefficients on the nasal and temporal side of the main line, (I) is applicable.

摘要： A process is disclosed for producing a photosensitive object that consists of a polymer and contains at least one spirooxazin compound. The process has the following steps: an acrylate monomer or a methacrylate monomer or a mixture of several such monomers is used as polymerisable monomer; the photosensitive dyestuffs and a polymerisation initiator are mixed with the polymerisable monomer; the thus obtained mixture is introduced into a casting mould, polymerised and hardened. The invention is characterised in that several photosensitive dyestuffs, of which at least one is not a spirooxazin, are added in order to obtain a polymerisable mixture having a neutral grey, neutral brown or green photosensitive coloration; in that the concentration of spirooxazin compounds does not exceed 0.045 % by weight, in relation to the mass of the monomer used; and in that the polymerisation initiators amount to more than 1 % by weight, in relation to the mass of the monomer used.

摘要： A progressive spectacle lens has a convex front surface and a concave inner surface. At least one of these surfaces provides an increase in effect from an area suitable for long-sight, via a progression area up to an area suitable for near-sight, along a plane or sinuous main meridian along which the total astigmatism is 0.5 dpt. To form additional seeing channels, the effect-increasing surface(s) has at least one additional line that does not intersect the main meridian extending from the long-sight area to the lower edge of the spectacle lens and along which the surface astigmatism has a local minimum value. Better viewing possibilities are thus provided, especially when several vertical areas have to be successively observed without moving the head.

摘要： Beschrieben wird eine photochrome Verbindung, die in an sich bekannter Weise ein Spirooxazin-Gerüst aufweist. Erfindungsgemäß sind an das Grundgerüst konjungierte Diazol-naphtoxazin bzw. Oxazol-, Thiazol-, Benzooxazol-oder Benzthiazol-Systeme angelagert. Hierdurch ergibt sich eine verbesserte Absorption im Wellenlängenbereich > als 350nm sowie verbesserte Migrationseigenschaften.

摘要： A holder for optical elements such as lenses etc., in which an elastic material is applied on the peripheral edge of the optical elements. The optical elements have, on their cylindrical peripheral surfaces, preferably three highly elastic ribs, which are compressed in the container upon insertion of the optical element. In this way, the centering of the optical system, for example a lens, is significantly improved.

摘要： A multi-layered reflection-reducing coating for an optical element made of organic material with phototropic properties. The coating is characterized by the fact that the reflection of the coating transmitted in the spectral range between 330 nm and 380 nm is less than 4% and the reflection in the spectral range between 290 nm and 330 nm is greater than 15%. This reflection behaviour ensures that the excitation of the phototropic effect with unduly short-wave light does not reduce the duration of the phototropic effect. In addition, by appropriately selecting the reflection properties, it is possible to achieve a desired excitation of phototropic molecules incorporated in specific steric places, and thus an influence on the kinetics and colour of the phototropic effect.

摘要： Beschrieben wird ein Brillenglas mit einer vorderen und einer augenseitigen Begrenzungsfläche sowie mit einem sich ändernden Brechungsindex, der zur Korrektur der Abbildungsfehler beiträgt.
Das erfindungsgemäße Brillenglas zeichnet sich durch wenigstens eine Schar von Niveauflächen (n(x,y,z)=const.) mit konstantem Brechungsindex aus, die in Richtung ihrer Flächennormalen in allen Punkten jeweils gleichen Abstand haben (Parallelflächen), und die bzw. deren Verlängerung die Achse, die die Glasscheitel der Vorderfläche und der augenseitigen Fläche verbindet, schneiden.摘要翻译： 描述了一种具有前部和眼侧边界表面，以及与这有助于像差的校正的变化的折射率的眼科透镜。 根据本发明的眼镜镜片的特征是等电位面中的至少一个家族（N（X，Y，Z）=常数）具有恒定的折射率，在其表面的所有点处的正常各方向具有相同的距离（平行面），以及或它们的 延伸，其连接所述前表面和眼球侧表面相交的玻璃顶点轴线。
