Apparatus for reducing fatigue and/or strain in the eyes of a person viewing an object at relatively close range. The apparatus includes means (10) for automatically repositioning the object relative to the eyes at least periodically whereby causing a shift in the focus of the eyes and a corresponding shift in tension of muscles associated with the eyes. In a preferred embodiment the object is repositioned such that the shift in tension of the eye muscles is substantially constant.

Ledit appareil comporte un organe (10) permettant de repositionner automatiquement l'objet par rapport aux yeux au moins périodiquement, ce qui provoque un décalage du foyer oculaire et un changement correspondant dans la tension des muscles associés aux yeux. Selon une réalisation préférée, l'objet est repositionné de telle sorte que le changement de tension des muscles oculaires est sensiblement constant.
