The present disclosure refers to a rearview device, in particular a rearview mirror device (1000, 4000, 5000) for a motor vehicle, comprising: a rearview element (1100, 3100, 4100, 5100) including a first layer and a second layer; a housing (1200, 3200, 4200, 5200) supporting at least a portion of the rearview element (1100, 3100, 4100, 5100); a light transmitting region (1140, 3140, 4240, 5140) formed to penetrate the second layer of the rearview element (1100, 3100, 4100, 5100); a light emitter (1321, 2321, 3321, 3371, 4321, 5321) for emitting a first light (l1) including a first wavelength (w1) in a first direction through the light transmitting region (1140, 2140, 3140, 4240, 5140); and a light receiver (1323, 2323, 3323, 3373, 4323) for detecting a second light (l2) entering a second direction through the light transmitting region (1140, 2140, 3140, 4240, 5140), the second light (l2) entering the second direction including a second wavelength (w2) corresponding to the first wavelength (w1), wherein a first function of the rearview device or an electrically operating configuration connected with the rearview device is executed when the second light (l2) including the second wavelength (w2) corresponding to the first wavelength (w1) is detected by the light receiver (1323, 2323, 3323, 3373, 4323) by a predetermined amount or more during a predetermined period (pth), and wherein a transmittance of the first layer is larger than a transmittance of the second layer, or wherein a function of the rearview device or an electrically operating configuration connected with the rearview device is executed when an object is located within a certain distance from light transmitting region (1140, 2140, 3140, 4240, 5140), and wherein a transmittance of the first layer is larger than a transmittance of the second layer.
