Dynamic mirror assemblies are disclosed that can vary the amount of light reflected, that include a mirror and a switching material. The switching material is placed between the mirror and a viewer, and has a dark state and a light state, and switches state in at least one direction due to a photochromic reaction, and switches in the other direction due to one or more of a photochromic reaction or an electrochromic reaction or a thermal reversion above a threshold temperature.
