Title
(EN) PRISM SECTION LENS SPECTACLES
(FR) LUNETTES A VERRES PRISMATIQUES
Abstract
(EN)
Spectacle lenses have upper (33) and lower (34) viewing sections, the upper section (33) comprising a combined pair of prisms which refract light rays to angularly modify a line of sight from a viewer therethrough to an intermediate and elevated object, e.g., and item on a video display screen (11) so that the item is perceived at a lower, laterally outward, and more distant position.
(FR)
Verres de lunettes ayant des zones de vision supérieures (33) et inférieures (34). La zone supérieure (33) comprend une paire combinée de prismes qui dévient par réfraction les rayons lumineux, afin de modifier l'angle d'une ligne de vue tracée entre l'observateur, en passant par ledit verre, et un objet intermédiaire élevé, par exemple un objet affiché sur un écran vidéo (11), de façon à ce que l'objet soit perçu en une position extérieure latérale, plus basse et plus éloignée.
