Abstract

A vehicle rear-view mirror has a light-transmitting filtering layer for filtering out interfering fractions of the light entering the filtering layer in the yellow spectral range. The mirror includes an interference reflector which has a plurality of thin layers for the reflection of the light impinging on the mirror. The degree of reflection of the interference reflector is less in the yellow spectral range than in the green and/or red wavelength range.
