Abstract: An eye shade is provided for vehicle drivers which separately but simultaneously shields the two eyes of the driver against the blinding glare of direct sunlight in the daytime or of approaching vehicle headlights at night, while leaving the space between and outside the shielded zones clear. The eye shade desirably consists primarily of a laterally extending series of contiguous substantially vertically disposed, electrically darkenable cells or zones such as liquid crystals, each of which cells or zones has the characteristic that it is transparent when no voltage is applied to it, but that it becomes progressively opaque with increase of applied voltage. The applied voltage is controlled by a laterally extending array of contiguous photosensitive sensor cells, each characterized by the fact that its electrical resistance increases as intensity of light exposure diminishes.
