Abstract
A mirror system, comprising a spectrally selective liquid crystal reflective assembly, designed and constructed to substantially absorb or transmit light at wavelengths corresponding to mesopic conditions, while reflecting light at other wavelengths. In one embodiment, the reflectance level of the mirror system is altered in response to a voltage applied across the selective liquid crystal reflective assembly.
