TL;DR: A variable-density vehicle glare shield has a mount which supports at least two transparent shields so that they can be individually swung to and from a position in front of the eyes of a driver of the vehicle as discussed by the authors.
Abstract: A variable-density vehicle glare shield has a mount which supports at least two transparent shields so that they can be individually swung to and from a position in front of the eyes of a driver of the vehicle. The shields are of different colors, e.g. one yellow and one blue. Either shield can be used by itself, or both shields can be used together, thereby obtaining not only a different color for the composite shield made up of two overlying individual shields, but also permitting the driver to vary the shield-color density in accordance with prevailing light conditions.
