A visual aid for directing incident light rays received from an object source onto remaining optically responsive portions of an eye comprises a first light reflecting optical element (4) resistively pivotally attached to a frame (8), such that the pivot axis (10) is in a generally horizontal plane; and, a second light reflecting optical element (22) resistively pivotally attached to the frame (8), such that the pivot axis (10) is in a generally horizontal plane. The second light reflecting optical element (22) is laterally spaced from the first light reflecting optical element (4) such that the first and second light reflecting optical elements (4), (22) cooperate to direct the incident light onto the remaining optically responsive portions of the eye (32). In a different embodiment of the present invention, at least one corrective lens (36) is positioned between the object source (34) and the optically responsive portion of the eye (32). The present invention also includes the method of using two laterally spaced resistively pivotal light reflecting optical elements cooperating together to redirect incident light onto an optically responsive portion of an eye, as well as the visual aid produced by such method.

Un accessoire visuel destiné à diriger des rayons de lumière incidente reçus d'une source d'objet sur les parties optiquement réactives restantes d'un oeil comprend un premier élément optique photoréfléchissant (4) fixé pivotant de manière résistive à un cadre (8), de telle manière que l'axe pivot (10) se trouve dans un plan d'une manière générale horizontal, et, un second élément optique photoréfléchissant (22) fixé pivotant de manière résistive au cadre (8), de telle manière que l'axe pivot (10) se trouve dans un plan d'une manière générale horizontal. Le second élément optique photoréfléchissant (22) est espacé latéralement du premier élément optique photoréfléchissant (4) de telle manière que les premier et second éléments optiques photoréfléchissants (4), (22) coopèrent pour diriger la lumière incidente sur les parties optiquement réactives (32). Dans un mode de réalisation différent de la présente invention, au moins une lentille correctrice (36) est positionnée entre la source d'objet (34) et la partie optiquement réactive de l'oeil (32). La présente invention concerne également le procédé d'utilisation de deux éléments optiques photoréfléchissants espacés latéralement et pivotant de manière résistive coopérant ensemble pour rediriger la lumière incidente sur une partie optiquement réactive d'un oeil, de même que l'accessoire visuel produit par ce procédé.
