Abstract
(DE)
Binokulares Einblickgerät zum objektiven und subjektiven Prüfen der Augen einer Person, und Verfahren zum direkten, entfernten und automatisierten Betreiben eines solchen Einblickgeräts, mit einem Gehäuse, mit zwei am Gehäuse vorgesehenen Einblicköffnungen zum Einblicken in das Gehäuse entlang jeweils einer Einblickachse, wobei im Gehäuse für jedes Auge eine Messeinheit mit einem Bildschirm zur Erzeugung von Sehzeichen vorgesehen ist, dadurch gekennzeichnet, dass die Messeinheit für jedes Auge eine verstellbare Sehschärfelinsenanordnung zur Bestimmung der Refraktion des jeweiligen Auges umfasst,dass im Gehäuse für jedes Auge eine entlang einer X-Achse und/oder einer Y-Achse verfahrbare Ausrichteinheit zum Ausrichten des vom jeweiligen Bildschirm erzeugten Lichtpfads hin in das jeweilige Auge vorgesehen ist, dass eine sich durch ein Verfahren der jeweiligen Ausrichteinheit sich ergebenden Distanzänderung des Lichtpfads zwischen dem Bildschirm und dem Augenhintergrund ausgeglichen wird.
(EN)
A binocular sight testing device for objective and subjective testing of the eyes of a person, and method for direct, remote and automated operation of such a sight testing device, comprising a housing, comprising two viewing openings, provided on the housing, for gazing into the housing along a respective viewing axis, wherein a measuring unit with a screen for producing optotypes is provided in the housing for each eye, characterized in that the measuring unit comprises, for each eye, an adjustable visual acuity lens arrangement for determining the refraction of the respective eye, in that provided in the housing for each eye there is an alignment unit, displaceable along an X-axis and/or a Y-axis, for aligning the light path produced by the respective screen into the respective eye, and in that there is compensation of a change in distance of the light path between the screen and the eye fundus, which arises from a displacement of the respective alignment unit.
(FR)
La présente invention concerne un testeur de vue binoculaire pour examiner de manière objective et subjective les yeux d'une personne, et procédé pour faire fonctionner directement, à distance et automatiquement un tel testeur de vue, comprenant un boîtier, deux ouvertures de visionnage prévues dans le boîtier pour regarder dans le boîtier respectivement le long d'un axe de visionnage, une unité de mesure, comprenant un écran de visualisation pour produire des optotypes, étant prévue dans le boîtier pour chaque œil. L'invention est caractérisée en ce que l'unité de mesure pour chaque œil comprend un dispositif de lentille d'acuité visuelle réglable pour déterminer la réfraction de chaque œil, de manière à ce que dans le boîtier pour chaque œil, une unité d'alignement réglable le long d'un axe X et/ou d'un axe Y soit prévue pour aligner le trajet lumineux, produit par l'écran de visualisation, dans l’œil respectif, de manière à compenser un changement de distance du trajet lumineux se produisant avec le procédé de chaque unité d'alignement respective entre l'écran de visualisation et le fond d’œil.
