<p>A vision field expansion device for a vehicle. The vision field expansion device for a vehicle is made of a transparent material. One side of the device is a flat surface or a curved surface, and the other side is of a concave and/or convex multiple faceted structure formed by grooves. None or any part of the facet surface forming the protruding angles on the multiple faceted structure is perpendicular to the flat surface or the curved surface. The vision field expansion device for a vehicle is integrated into or directly applied onto the windshield glass or window glass to expand the vision field of the driver, such that the driver can clearly see the situation in front of and at the back of the vehicle during vehicle reversing and starting. The device better eliminates blind spots, and is low in cost, easy to manufacture, and convenient to install.</p> |
