A lens for a vehicle rearview mirror includes a light-transmissible glass substrate, which has a first surface and a second surface opposite to the first surface, a first coating layer, which has a reflectivity of 10-20% and is coated on the first surface of the glass substrate and defines with the first surface of the glass substrate a first transmission zone, a second coating layer, which has a reflectivity of 40-55% and is coated on the whole area of the second surface of the glass substrate, and a back layer, which is covered on the second coating layer and defines with the second coating layer a second transmission zone corresponding to the first transmission zone.
