Claim:
1. Eyeglasses for viewing stereoscopic images or a perspective sub-image of a stereoscopic image, the eyeglasses comprising: an interference filter for a right eye and an interference filter for a left eye, each interference filter formed of at least one photosensitive polymer film, and including separate filter regions, wherein, in each interference filter, at least two of the separate filter regions are arranged stacked along at least one normal line that is substantially perpendicular to a first outside surface between a first point, where the at least one normal line pierces the first outside surface, and a second point, where the at least one normal line pierces a second outside surface, wherein the separate filter regions have a residual transmission of less than 10%, such that the separate filter regions are nearly opaque, along the at least one normal line for a given predefined wavelength interval of the electromagnetic spectrum, and wherein the at least two of the separate filter regions stacked along the at least one normal line are arranged within a single photosensitive polymer film of the at least one photosensitive polymer film, wherein, in each interference filter, at least two of the separate filter regions are arranged stacked along a second normal line that is laterally offset from the at least one normal line, wherein at least one of the at least two of the separate filter regions stacked along the second normal line is different from at least one of the at least two of the separate filter regions stacked along the at least one normal line.
