An exterior mirror reflective element includes a glass substrate having a first surface and a second surface. The mirror reflective element has a principal reflector portion and an auxiliary reflector portion, with the auxiliary reflector portion having a curved recess established at the second surface of the glass substrate. The curved recess has a cross-dimension size that may be less than about 80 millimeters and a radius of curvature that may be less than about 1,000 millimeters and a maximum recess depth that may be in the range from about 0.11 millimeters to about 2.26 millimeters. A metallic reflector is established at the curved recess and a principal mirror reflector is established at the principal reflector portion. The mirror reflective element may be an electrochromic mirror reflective element, or may be a fixed reflectance non-electro-optic mirror reflective element.
