Abstract

The original device is a scale used in centring, which is adhered to framed or frameless spectacles. It has a measurement scale printed on the front and is made of stamped-out polyvinyl chloride sheet. On the rear, there is double-sided adhesive tape. This is detachable and the device can be reused many times. The scale is like a rectangle with open base. Its side limbs are flexible and can be applied without distortion. The horizontal upper section (3) has a horizontal groove (4) about which it can be folded through about 90 deg . The folded section has a notch (5) dividing it into two sections (7). Just below the notch is a line (6). The folded sections (7) lie precisely on the upper edge of the frame. The notch allows the device to adapt to the curvature of the central section of the spectacles. The notch and line (6) assist in centring.

Diesen Druckschriften liegen Vorrichtungen zugrunde, die auf die Brillen­ fassung gehängt oder an ihr festgeschraubt werden. Da die beweglichen Lei­ sten oder Meßplatten, die Bestandteil dieser Vorrichtungen sind in unmittel­ barem Abstand vor den Probanden-Augen sitzen, ist eine Irritation, bedingt durch die unbewußte Nah-Akkomodation nicht auszuschließen. Zudem wird die Messung bei Probanden-Blickrichtung geradeaus nicht zuletzt durch das hohe Gewicht der Vorrichtungen verfälscht.These documents are based on devices on the glasses frame can be hung or screwed onto it. Because the moving lei Most or measuring plates that are part of these devices in immediate Sitting at a clear distance in front of the test person's eyes is an irritation cannot be ruled out due to the unconscious close accommodation. In addition, the measurement is straightforward not least when the subject is looking straight ahead falsified by the high weight of the devices.

Durch die Erfindung wird die Aufgabe gelöst, eine auf eine Brillenfassung auf bringbare Schablone bereitzustellen, die eine einfache und genaue Ermittlung der für die Brillenglaszentrierung notwendige Daten ermöglicht.The object is achieved by the invention, based on a spectacle frame Provide feasible template that is simple and accurate which enables the data necessary for lens centering.

Die federleichte Brillenglas-Anpaß-Schablone, deren seitliche Schenkel an den äußeren Enden der Brillenfassung haften, führt zu keinerlei Einschränkung des Gesichtsfelds. Eine unbewußte Nah-Akkomodation entfällt.The feather-light lens fitting template, the side legs on the stick to the outer ends of the spectacle frame leads to no restriction of the visual field. An unconscious close accommodation is no longer necessary.

Das Probandengesicht mit Brillenfassung und aufgebrachter Schablone wird mittels einer Videokamera in den Speicher eines Computers eingefroren. Nach Aufruf des Speicherbildes erfolgt die Anzeige am Monitor.The subject's face with glasses and a template applied frozen in the memory of a computer by means of a video camera. After calling up the memory image, it is displayed on the monitor.

Durch eine auf dem Rechner installierte Software Anwendung, kann die Brillenglaszentrierung nun durchgeführt und festgehalten werden.With a software application installed on the computer, the Glasses are now centered and held.
