An optical rear view system for a vehicle comprises a reflector mounted to receive light from objects to the rear of the vehicle and to reflect it towards an observer, provided with at least one further optical component between the reflector and the observer effective to direct towards the observer, by refraction or reflection, a portion of the light which upon reflection at the reflector is not directed towards the observer, whereby to provide a wider field of view than that obtainable from the reflector alone. The reflector is positioned forwardly of the observer so as to be in his field of view and the surface of the system on which light from an object behind the vehicle is first incident lies at an acute angle to the longitudinal axis of the vehicle and is inclined such that a forward part of the incident surface is further from the vehicle axis than a rearward part. |
