Vorrichtung zur Betrachtung einer optischen Information im. Bereich eines Brillenglases.Device for viewing optical information in the area of a spectacle lens.

BeschreibungDescription

jj Da eine Brille sich näher vor dem Auge befindet als der Nahpunkt desjj Since glasses are closer to the eye than the near point of the

s' Auges, werden Einzelheiten, wie ein Strich suf dem Brillenglas oder s ' eye, details such as a line on the lens or

Ü die Brillenfassung nur unscharf wahrgenommen.Ü the glasses frame is only perceived blurry.

Zweck der Erfindung ist, auf der Vorderfläche oder Hinterfläche des I The purpose of the invention is to provide on the front or rear surface of the I

Brillenglases einen Maßstab, Zahlen oder Buchstaben dem Träger der Brille scharf zur Ansicht zu bringen.to bring a scale, numbers or letters into sharp view for the wearer of the glasses.

Diese Aufgabe wird in der Erfindung auf folgende Weise gelöst:This object is achieved in the invention in the following way:

rline starke Lupe wird auf der augenseitigen Fläche eines Brillenglases s angebracht. Diese Lupe ist so stark, daß durch sie ein Gegenstand,rline strong magnifying glass is attached to the eye-side surface of a lens. This magnifying glass is so strong that an object,

der auf der Brillenglasvorder- oder rückfläche angebracht oder in das Brillenglas eingeschmolzen ist, mit dem Auge scharf gesehen werden kann.which is attached to the front or back surface of the lens or is fused into the lens, allows the eye to see clearly.

Ist dabei der Abstand zum Gegenstand kleiner als die einfache Brennweite, so ist das Bild virtuell aufrecht und vergrößert. Liegt der Abstand zum Gegenstand zwischen der einfachen und der doppelten Brennweite, so ist das Bild reell umgekehrt und vergrößert.If the distance to the object is smaller than the single focal length, the image is virtually upright and enlarged. If the distance to the object is between the single and double focal length, the image is actually inverted and enlarged.

Die Lupe auf der Innenseite des Brillenglases kann oberhalb des normalen Durchblickfeldes angebracht werden, so daß sie beim üblichen Gebrauch der brille nicht stört.The magnifying glass on the inside of the lens can be placed above the normal field of view so that it does not interfere with normal use of the glasses.

Informationen, die durch die Lupe sichtbar gemacht werden, können direkt verwendet v/erden oder -zum Beispiel als Maßstab- dem Bild des anderen Auges überlagert werden.Information made visible by the magnifying glass can be used directly or - for example as a scale - superimposed on the image of the other eye.

Striche können durch Zylinderlinsen anstelle der Lupe zur Ansicht gebracht werden.Lines can be viewed using cylindrical lenses instead of a magnifying glass.
