Abstract

Abstract An image control mirror, especially for trucks, commercial vehicles and the like, includes a housing, a transparent lens and a mirror-image providing surface on a member arranged within the housing. The surface can be located so as to extend to an angle in a range of about 2.25 or 2.3 to 3.9 times the distance in inches of transverse viewing width to the lens for safety to prevent glare and second and third images. Preferably, the angle is 3.4° per inch of width of the mirror or 20.5° in a six inch wide mirror that is sixteen inches high.
