The vehicle mirror and method of making same includes a portion of the viewing surface wherein the field angle increases at a constant or an increasing rate as the observer's eye travels outward across the mirror, and another portion wherein the field angle increases at a constant or 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 a constant or increasing rate, and a tertiary viewing area (20) still farther outward, having an aspherical convex curvature wherein the field angle increases at a constant or decreasing rate. A computer system for developing the mirror surface and mold surface is also disclosed.
