Claim:
A vehicle mirror assembly comprising: a base member; and a convex teardrop-shaped lens member mounted to said base member; said convex lens member having a first circular-shaped portion and a second elliptical-shaped portion; said first circular-shaped portion comprising a half circular planar edge portion having a first constant radius and a half spherical convex portion having a second constant radius; said second elliptical-shaped portion having a half elliptical planar edge portion and a half oval convex ellipsoidal portion; said second elliptical-shaped portion having a major radius of curvature along the major axis and a minor radius of curvature along the minor axis different from said major radius of curvature; said minor radius of curvature being the same as the second constant radius of said half spherical convex portion; whereby said first circular-shaped portion and said second elliptical-shaped portion merge smoothly together forming a convex teardrop-shaped lens member.
