The device (6) makes it possible for a person with eyes directed forwards to see an object placed beneath the eyes and employs first (1) and second (2) mirrors arranged so that they provide an optical path extending from the object to a reflective surface in the first mirror and then to a reflective surface in the second mirror (2), from which the path extends to the eyes. The device incorporates a body (10,12,13,17,18) which is so formed so that when the body and the mirrors are placed in front of and at a space from the body of a person with an upright upper body, with the hands of the person held in front of the upper body and the person looking directly forward, the person can see his or her hands. |
