1. An antiglare mirror, comprising:
- a first electrode layer;
a second electrode layer that is optically transparent;
a dichroic material sandwiched between the first and second electrodes layers and exhibiting a high optical absorption when the first and second electrode layers are biased at a first electrical bias state and a low optical absorption when the first and second electrode layers are biased at a second, different electrical bias state, wherein the dichroic material switches between the high optical absorption and the low optical absorption in less than 0.1 second; and
a control circuit coupled to the first and second electrode layers and operable to control electrical bias between the first and second electrode layers and thus optical absorption of the dichroic material.

Abstract
Devices that include a dichroic material sandwiched between first and second electrodes layers and exhibiting a high optical absorption when the first and second electrode layers are biased at a first electrical bias state and a low optical absorption when the first and second electrode layers are biased at a second, different electrical bias state. Such devices may be used to construct optically reflective devices such as anti-glare mirrors and optically transmissive devices such as eye glasses. The dichroic material may be selected to be operable to switch between the high optical absorption and the low optical absorption in less than 0.1 second.
