A plastic injection molded lens for a left and a right rear-view mirror of an automobile is injection formed into shape in a mold. The lens is formed integrally with a major mirror surface zone and a minor mirror surface zone that are different from each other in radian of curved surface. By so designing, the visual field of the rear-view mirror is much wider and produces no dead angles of vision; therefore, the rear-view mirror of this invention is needless to be adjusted for keeping away from the dead angles of eyesight. |
