<p>The arrangement has two mirrors (1,2) which abut or adjoin each other and form an acute angle wherein the reflective surfaces (4) face the inner angled area. The viewer can now get a good side view without having to turn his head relative to the mirror. The mirror is of special importance to people choosing spectacles who are short-sighted and would hitherto not be able to see the side view if standing further away as with hairdressers mirrors. The angle between the mirrors is pref. between 40 and 76 deg. If two further sectors are required between the two sectors which make up the side view to form a front view the angle is pref. 51.4 deg.</p> |
