Abstract
A dazzle-free reflection mirror, which may be used as an inner mirror or an outer mirror of a vehicle, has an electro-optical element of which transparency is changed by applying an electric field thereto in order to effectuate a dazzle-free operation. The dazzle-free reflection mirror comprises a dazzle-free portion to effectuate the dazzle-free operation at a lower part of the mirror surface and a non-dazzle-free portion not to effectuate the dazzle-free operation at the rest part of the mirror surface. The dazzle-free portion shields light from following-vehicle headlights at night so that the driver feels no glaring. The non-dazzle-free portion clearly images a rear view so that the driver can see an appearance of the following vehicle.
