Abstract
Partially transparent devices and methods that reduce actual and/or perceived glare by incorporating absorbing materials are described. Actual and/or perceived glare can be reduced by multi-path absorption in the device. Perceived glare is further reduced by accounting for the psychophysics of human visual perception as a function of wavelength, orientation, and field illuminance.
