Abstract of the Disclosure Rearview mirrors are disclosed having a convex curvature defined by mathematical and geometrical relation- ships between the position of the observer, the viewed objects, and the mirror. The mathematical relationships are designed to minimize bi-ocular distortions while producing the desired field of view. The mathematical relationships when expressed in incremental field angular relationships which correspond to constant vision angle increments may follow the formula .DELTA..delta.n = .DELTA..delta.(n-1)[1 + X]: where (n) defines a point along a generally horizontal line of the mirror surface, beginning at the optical design axis or at the edge of a primary viewing surface; .delta.n defines the angle from the axis to point (n); .DELTA..delta.n defines the incremental field angle between (n) and (n-1) and X is a constant factor chosen to produce a desired total field of view across the surface at a constant rate of horizontal optical distortion; or may follow the formula .DELTA..delta.n = .DELTA..delta.(n-1)[1 + (n/N) (2X)]; or may follow theformula .DELTA..delta.n = .DELTA..delta.(n-1)[1 + h + (n/N) (2X - 2h) where h isa value between 0 and X.
