Abstract
A system and method to polarize a reflective layer on a vehicle mirror to reveal a convex mirror to view objects in a vehicle blindspot includes a primary mirror having first and second surfaces, an electrically polarizable reflective coating on at least a portion of the first surface reflective in a depolarized state and clear when polarized by an applied electric current, a blind zone viewing convex mirror adjacent to the second surface and proximal to the polarizable coating of the first surface; and a blind spot detection system electrically connected to the primary mirror and a power source to automatically apply current to the first surface when an object is detected in a blind spot and change the reflectivity polarizable coating on the first surface and expose the concave mirror and discontinuing current to the reflective coating once an object has passed out of the blind spot.
