Abstract: A method for tinting a spectacle lens substrate includes providing a spectacle lens substrate made from a polymeric lens material, providing a composition having a polymeric carrier material, applying a pattern of the composition on a surface of the spectacle lens substrate, and heating the spectacle lens substrate to allow for diffusion of a dye substance between the carrier material and the lens material. Moreover, a composition for in-substrate tinting of a polymeric spectacle lens substrate and a spectacle lens substrate having a polymeric lens material which exhibits a pattern of a composition having a polymeric carrier material applied on a surface of the spectacle lens substrate are presented.

Abstract: A testing device for detecting defects of transparent test specimens, in particular of ophthalmological lenses, has an illumination device for transilluminating test specimens to be examined and with an image acquisition device for imaging the test specimen transilluminated by the illumination device. The illumination device includes a plurality of linearly adjustable light sources for generating a stripe pattern. To capture the stripe pattern, the acquisition duration of the image acquisition device can be adjusted in such a way that the light emitted by each of the light sources is detected as a light stripe. Further, the disclosure relates to a testing method for detecting a defect of a transparent specimen.

Abstract: The present invention relates to a pharmaceutical composition for stimulating angiogenesis and/or the treatment or prevention of hypovascularity and/or the prevention and/or treatment of an angiogenic disorder/disease, whereby the composition comprises specific compounds which may be obtained from Leontopodium alpinum Cass, (Edelweiss). These compounds relate to lignan compounds as shown in herein disclosed formula I. A preferred compound in this context is leologin—IUPAC name [(2S,3R,4R)-4-(3,4-dimethoxybenzyl)-2-(3,4-dimethoxyphenyl)tetxahydrofuran-3-yl]methyl (2Z)-2-methylbut-2-enoat], and even more particularly 5-methoxy-leoligin (IUPAC name: [(25,3R,4R)-4-(3,4-dimethoxybenzyl)-2-(3,4,5-trimethoxyphenyl)tetrahydrofuran-3-yl]methyl-(2Z)-2-methylbut-2-enoat) and derivatives thereof. Corresponding means and methods in respect of medical uses of these compounds are described.
