High definition vehicular mirror
View Patent ↗A vehicle mirror assembly having a housing or base member, a mirror lens and a connecting gasket member. The mirror lens is provided in the shape of a portion of an end of an ellipsoid. The lens has a varying radius of curvature. The center portion of the tens 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.

13. A mirror assembly comprising:
a mirror lens member comprising a dome lens generally configured to conform to a geometric shape formed using an ellipse, said mirror lens member comprising a first base portion and a second base portion comprising an intersection of an axis of said ellipse, said intersection being non-perpendicular to said axis.
14. A mirror assembly as described in claim 13 , wherein said axis of said ellipse comprises a major axis.
15. A mirror assembly comprising:
a mirror lens member comprising first base periphery, a second base periphery, and a dome lens having a varying dome lens radius of curvature, said varying dome lens radius of curvature configured to generate a first proportion image view located between said first base periphery and said second base periphery, said varying dome lens radius of curvature configured to generate at least one second proportion image view along said first base periphery and said second base periphery, said varying dome lens radius of curvature being greater at said first base periphery than at said second base periphery;
