INSTALLATION FOR IMPROVING THE BINOCULAR VISUAL FIELD

摘要

An installation (50) for improving the binocular visual field in the presence of a structural element (52) located at a distance from the observer equal to or greater than the observer's interpupillary distance, characterised in that said structural element (52) is provided with at least one through aperture (54) in which an optical system (56) is applied com prising two convergent lenses (58, 62), between which a divergent lens (60) is centrally interposed, the distance between each of said convergent lenses (58, 62) and said central divergent lens (60) being such as to render said optical system (56) of neutral afocal type.
