Abstract:
A mirror lens for exteriorly mounting onto a vehicle, the mirror lens serving to broaden the field of view for a driver, the mirror lens comprising:a front surface, a rear reflective surface, a first edge, a second edge, a pair of side edges extending between the first edge and second edge, a first substantially horizontally oriented arc extending between a midpoint of each of the pair of side edges and having a constant radius of curvature, a second substantially vertically oriented arc extending between a midpoint of the first edge and a midpoint of the second edge such that the intersection of the first arc and the second arc defines the center of the lens, a first portion of the lens disposed on one side of the first arc and a second portion of the lens disposed on a side of the first arc opposite the first portion, and wherein the mirror has a first continuously varying radius of curvature from the first edge to the second edge such that the first radius of curvature of the first portion is always greater than the first radius of curvature of the second portion, and further wherein the mirror is substantially symmetric about the second arc, and further wherein the first portion is narrower than the second portion, the lens having a substantially trapezoidal configuration.
