Abstract
The invention is directed to an apparatus for demonstrating the visual impression for a wearer of spectacles having polarizing spectacle lenses. The apparatus includes a memory for providing a first image having a motif and a first polarization direction corresponding thereto and a second image having the same motif and a second polarization direction corresponding thereto, which is different from the first polarization direction. The apparatus also includes a display device for displaying the first image with light polarized in the first polarization direction and the second image with light polarized in the second polarization direction in a superposed representation, such that the motif of the first image and the motif of the second image coincide dimensionally identically. The invention is also directed to a method for demonstrating the visual impression for a wearer of spectacles having polarizing spectacle lenses.
