Patent number: 6965385Abstract: 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.Type: GrantFiled: February 13, 2002Date of Patent: November 15, 2005Assignee: Rodenstock GmbHInventors: Andrea Welk, Helmut Altheimer, Peter Baumbach, Gregor Esser, Walter Haimerl

Publication number: 20040095553Abstract: A spectacle lens having in a first see-through region a power suitable for distant viewing in a wearing position, and in a second see-through region a power suitable for medium-distance viewing, i.e. for distances of about 1 meter and more, in a wearing position, and in which the power continuously increases from the first see-through region along a plane or winding principal line to the second see-through region. The spectacle lens has the following features: the power increases not only from the first see-through region to the second see-through region, but also continuously to beyond the second see-through region to a lower edge of the spectacle lens; and a region of clear vision, i.e. a region in which a residual astigmatism of a system spectacle-lens/eye does not exceed 0.5 dpt, narrows below the first see-through region towards the lower edge of the spectacle lens to have a funnel-shaped configuration, i.e. without any constriction.Type: ApplicationFiled: November 26, 2003Publication date: May 20, 2004Inventors: Rainer Dorsch, Walter Haimerl
