Description
Schutzgläser für Brillen und optische Instrumente. Bisher sind als Schutzgläser gefärbte oder über die ganze Fläche gedunkelte Gläser verwandt worden oder Blenden, die ein im Bedarfsfall erweiterbares Sehloch hatten.Protective glasses for glasses and optical instruments. So far as Protective glasses colored or darkened over the entire surface have been used or diaphragms that had a viewing hole that could be expanded if necessary.
Die Verfärbung hat den Nachteil, daß der gesehene Gegenstand anders erscheint, als er tatsächlich gefärbt ist. Wendet man jedoch eine Lochschutzblende an, so wird das Gesichtsfeld mit der Verkleinerung des Sehloches und der Entfernung der Blende vom Auge verringert.The discoloration has the disadvantage that the object seen is different appears as it is actually colored. However, if you turn a hole protection cover the field of view increases with the decrease in the size of the eye hole and the distance the aperture of the eye is reduced.
Gemäß der vorliegenden Erfindung wird der Schutz des Auges dadurch erreicht, daß auf dein ungefärbten Schutzglas wenig oder gar kein Licht durchlassende Striche aufgetragen oder eingeätzt sind, die vom Schutzglasrande radial nach dem Sehloch verlaufen, so daß zwischen diesen Strichen Licht durchlassende Zwischenräume entstehen. # Die frei bleibenden Zwischenräume ermöglichen eine volle Ausnutzung des Gesichtsfeldes; die Striche schützen das Auge gegen zu starke einfallende Lichtstrahlen.According to the present invention, the protection of the eye is thereby achieved achieves that little or no light transmitting on your uncolored protective glass Lines are applied or etched in from the protective glass edge radially after Eye holes run so that light-permeable spaces between these lines develop. # The remaining free spaces enable full utilization of the field of view; the lines protect the eye against too strong incident light rays.
Abb. i der Zeichnung stellt ein Schutzglas mit dein Rande a dar, das ein Sehloch s besitzt. Die Schutzstriche b verlaufen bis zu dem Sehloch s, die Schutzstriche c und d sind verkürzt.Fig. I of the drawing shows a protective glass with the edge a, which has a viewing hole s . The protective lines b run up to the viewing hole s, the protective lines c and d are shortened.
Abb. 2 veranschaulicht ein Strichschutzglas mit einem nach oben und der Seite verschobenem Sehloch.Fig. 2 illustrates a line protection glass with an upward and the side shifted eye hole.
Die Strichschutzgläser sind bei Schutzbrillen anzuwenden für Eisenbahnbeamte, Seeleute, Autofahrer, Hochtouristen, Skiläufer, Aviatiker und für Augenkranke, deren Iris der Einwirkung der Lichtstrahlen nicht genügend folgt (bei Iritis, Iridektomie und in ähnlichen Fällen).The line protection glasses are to be used with protective goggles for railway officials, Seafarers, motorists, high tourists, skiers, aviators and for those with eye diseases, theirs The iris does not sufficiently follow the action of the light rays (in iritis, iridectomy and in similar cases).
Bei optischen Instrumenten *kommen die Strichschutzgläser besonders für die Beobachtung von Schmelzfarben und stark leuchtenden Himmelskörpern in Betracht.The line protection glasses are particularly useful for optical instruments * for the observation of enamel colors and strongly luminous celestial bodies.
Der Vorteil der Strichschutzgläser gegen die bisherigen Schutzgläser liegt darin, daß die Gegenstände durch sie in unveränderter Farbe und Färbung gesehen werden, und daß durch sie das Gesichtsfeld nicht verringert wird.The advantage of line protection glasses over the previous protection glasses lies in the fact that the objects seen through them in unchanged color and coloring and that they do not reduce the field of vision.
