Abstract

L'invention concerne un procédé et un appareil permettant d'atténuer le niveau de fatigue oculaire. Ledit appareil se compose d'un boîtier extérieur, d'un tube de visualisation, d'un appareil de formation d'image au niveau du fond de l'oeil, d'un appareil d'activation du fond de l'oeil, d'une source d'alimentation, d'un contrôleur et d'un générateur de son. L'invention utilise une pluralité de spectres visuels différents sensibles aux cellules de la rétine chez l'humain de manière à produire des images en deux dimensions ainsi que des images de convergence. Pour être visualisées ces images nécessitent une adaptation visuelle qui permet au patient d'exercer sa vue par le biais du système de réception visuelle. Il est donc possible, grâce à cette invention, de récupérer une vision normale, d'améliorer le traitement et de maintenir une bonne acuité visuelle. De plus, l'utilisation de la micro-informatique permet d'assurer un traitement visuel automatique de même qu'un fonctionnement automatique de l'appareil faisant l'objet de cette invention, ce qui en facilite la manipulation.
