Abstract
A vehicle mirror, and a mold for making same, each includes a portion of the viewing surface wherein the field angle increases at an increasing rate as the observer's eye travels outward across the mirror, and another portion wherein the field angle increases at a decreasing rate as the observer's eye travels across the mirror surface. In one embodiment, the mirror includes a primary viewing area (16) nearest to the observer (14) having a spherical convex surface, a secondary viewing area (18) somewhat farther from the observer, having an aspherical convex surface wherein the field angle increases at an increasing rate, and a tertiary viewing area (20) still farther outward, having an aspherical convex curvature wherein the field angle increases at a decreasing rate.
