Description

Durch die Einführung der Augenhaftgläser ist, man dem Ideal der unsichtbaren Brille um ein beträchtliches Stück näher gekommen. Störend wirkt lediglich für den Betrachter der gläserne Glanz der Haftgläser.By introducing the eye-catching glasses, one is the ideal of the invisible Glasses come a good deal closer. Disturbing only works for the Viewers of the glass shine of the adhesive glasses.

Die vorliegende Erfindung bezweckt, diesen Glanz so weit abzuschwächen, daß er sich von dem natürlichen Glanz der Augen praktisch nicht mehr unterscheidet. Dies wird durch Verwendung mindestens einer reflexändernden Oberflächenschicht auf dem Haftglas ereicht. Im Gegensatz zu reflexvermindernden Schichten auf Glas-Luft-Flächen haben diese jedoch die Bedingung zu erfüllen, daß der Brechungsindex, falls es sich um eine einfache reflexvermindernde Schicht handelt, zwischen dem Brechungsindex des Haftglases und dem der Tränenflüssigkeit liegt. Diese Bedingung ist durch verschiedene Arten von Einfachschichten zu verwirklichen, von denen offensichtlich nur solche im Sinne der vorliegenden Erfindung Verwendung finden können, welche gleichzeitig mechanisch genügend fest und in der Tränenflüssigkeit völlig unlöslich sind. Als besonders gut geeignet erweisen sich die subtraktiven Oberflächenschichten, bei denen die Änderung der Brechzahl durch Entfernung gewisser Glasbestandteile auf chemischem oder elektrischem Wege erfolgt. Bei additiven Schichten ist es unter Umständen schwierig, die Forderung einer zwischen den Brechzahlen von Haftglas und Tränenflüssigkeit liegenden Brechzahl gleichzeitig mit der der chemischen Unangreifbarkeit zu erfüllen; in diesem Falle kann es daher zweckmäßig sein, statt einer einfachen Schicht zwei oder mehrere Schichten aufzubringen, deren Brechzahlen und Dicken dann nach bekannten rechnerischen Verfahren festzulegen sind und für sich allein die obenerwähnte Bedingung nicht mehr zu erfüllen brauchen, aber durch ihr Zusammenwirken die gestellte Bedingung erfüllen.The present invention aims to weaken this gloss so far that that it practically no longer differs from the natural gloss of the eyes. This is done by using at least one reflection-changing surface layer reached the adhesive glass. In contrast to reflection-reducing layers on glass-air surfaces However, these have to meet the condition that the refractive index, if it is is a simple reflection-reducing layer, between the refractive index of the adhesive glass and that of the tear fluid. This condition is due to various To realize kinds of single layers, of which obviously only such in the context of the present invention can be used which simultaneously mechanically strong enough and completely insoluble in the tear fluid. as The subtractive surface layers prove to be particularly suitable which change the refractive index by removing certain glass components takes place chemically or electrically. In the case of additive layers, it is under Difficult circumstances, the requirement of a between the refractive indices of adhesive glass and Tear fluid lying at the same time as the refractive index of chemical invulnerability to meet; in this case it may be useful instead of a simple one Layer to apply two or more layers, then their refractive indices and thicknesses are to be determined according to known arithmetic methods and for themselves the No longer need to meet the above-mentioned condition, but through their interaction meet the specified condition.

Zu erwähnen ist noch, daß die Oberflächenschichten auch durch Aufdampfen bzw. Zerstäuben entsprechender Stoffe erzeugt «-erden können.It should also be mentioned that the surface layers are also made by vapor deposition or the atomization of corresponding substances.

In der Abbildung ist ein Ausführungsbeispiel des neuen Augenhaftglases i mit einer reflexvermindernden Schicht 2 schematisch im Querschnitt dargestellt. Die Schicht 2 ist übertrieben dick wiedergegeben.The illustration shows an exemplary embodiment of the new adhesive eye glass i shown schematically in cross section with a reflection-reducing layer 2. Layer 2 is shown exaggeratedly thick.
