High definition vehicular mirror
View Patent ↗A vehicle mirror assembly having a housing or base member, a mirror lens and a bezel member. The mirror lens is provided in the shape of a portion of an end of an ellipsoid and has a varying radius of curvature. The center portion of the lens has a smaller radius of curvature than the outer portions along the major axis of the lens creating an improved field of view of the reflected image. The bezel is positioned over the intersection of the housing and mirror lens.
