Abstract
An optical device includes variable optical material that alters at least one of: incident ambient light, spectral content of incident ambient light or direction of incident ambient light through the optical device in response to a stimulus provided by the device. The device can sense intensity and/or spectral characteristics of ambient light and provide appropriate stimulus to various portions of the optical device to activate the variable optical material and alter at least one of: incident ambient light, spectral content of incident ambient light or direction of incident ambient light.
