ABSTRACT:
A rearview device for a headpiece comprises an optical system which is mountable on the headpiece and includes an objective lens which is directed rearwardly of the wearer of the headpiece for receiving light from an object to the rear of the wearer and forming an image of the object. An eyepiece lens enables the wearer of the headpiece to view the image. Laterally and vertically inverting reflectors in the path of light rays passing through the objective lens and the eyepiece lens ensure that the image of the object that is viewed by the wearer is erect and without inversion. A deflecting member is disposed in the path of light rays passing from the objective lens to the eyepiece lens for deflecting the light rays to follow a convexly angled path without affecting the orientation of the image.
