ABSTRACT:
Provided is an improved rear view or rear vision mirror for passenger automobiles, vans and like vehicles, exclusive of buses or trucks larger than pick-up trucks, which mirror affords a wide-angle view well beyond the statutory requirement that outside mirrors give a view of the side of the vehicle through a 10.degree. angle beyond such side of the vehicle to the extent that the image covers the so-called "blind spot" beyond the 10.degree. view path. The improved mirror avoids the use of spherical reflective surfaces and consists essentially of a single substantially planar reflective surface and a single contoured reflective surface that is a generally convex cylindrically contoured surface having a radius of curvature within a critical range of values.
