Abstract
A method of reducing glare may include sensing a first light source with a second vehicle, and sensing a second light source with a first vehicle and oscillating a first light source ICF between a substantially opaque state and a substantially clear state on a first schedule. A second windscreen ICF may be oscillating between the substantially opaque state and the substantially clear state on a second schedule different from the first schedule. A position of the light source may be sensed and an eye position of the occupant estimated. An intersecting region of the selectively-darkenable ICF, which is located substantially along a line from the position of the light source to the eye position, is calculated. The intersecting region of the ICF is darkened, such that a reduced amount of light from the light source passes through the intersecting region.
