Abstract
Description
Bifokallinse vom bivisuellen Typ Bifocal lens of the bivisual type
Die Erfindung betrifft eine Bifokallinse vom bivisuellen Typ mit konzentrisch zueinander angeordnetem Nah- und Fernteil.The invention relates to a bifocal lens of the bivisual type with concentric near and far part arranged to one another.
Bei konzentrischen Bifokallinsen nach dem simultanen bzw.With concentric bifocal lenses after the simultaneous or
bivisuellen Prinzip liegt beispielsweise in der Linsenmitte der Fernteil und konzentrisch um diesen der Nahteil, welche gleichzeitig vor der Pupille liegen. Die Bifokallinse nach dem simultanen bzw. bivisuellen Typ bildet simultan die Ferne und Nähe auf der Netzhaut ab. Im zentralen Nervensystem wird dasjenige Bild ausgewählt, auf das sich der Kontaktlinsenträger konzentriert. Bei raschem Hell-Dunkel-Wechsel öffnet sich die Pupille rasch und das Flächenverhältnis der davor liegenden Nah- und Fernzone ändert sich entsprechend.The bivisual principle lies in the middle of the lens, for example, in the distant part and concentrically around this the near part, which at the same time lie in front of the pupil. The bifocal lens of the simultaneous or bivisual type simultaneously forms the distance and sew down on the retina. In the central nervous system, that image is selected on which the contact lens wearer focuses. With rapid light-dark change the pupil opens quickly and the area ratio of the near- and far zone changes accordingly.
Dies kann zu vörubergehender Visusminderung führen. Insbesondere bei Tunneldurchfahrten oder bei Einfahrten in Tiefgaragen ergibt sich aufgrund der Pupillenerweiterung die genannte Beeinträchtigung beim Sehen.This can lead to temporary loss of vision. Especially with Passing through tunnels or entering underground garages results from the dilated pupil the said impairment in vision.
Aufgabe der Erfindung ist es daher, eine Bifokallinse der eingangs genannten Art zu schaffen, bei der bei raschem Hell-Dunkel-Wecksel das Sehvermögen nicht beeinträchtigt wird.The object of the invention is therefore to provide a bifocal lens of the initially mentioned to create the type mentioned, in the case of rapid light-dark wake up the eyesight is not affected.
Diese Aufbage wird erfindungsgemäß dadurch gelöst, daß der Nah- und Fernteil in mehrere konzentrische Kreisringflächen aufgeteilt ist, die in radialer Richtung alternierend angeordnet sind.This Aufbage is solved according to the invention in that the near and Fernteil is divided into several concentric circular ring surfaces, which are in radial Direction are arranged alternately.
In bevorzugter Weise kan das Flächenverhältnis (Fläche des bzw. der kreisringförmigen Nahteile/Fläche des bzw. der kreisringförmigen Fernteile) ausgehend von der Linsenmitte in radialer Wichtung zuin Linsenrand hin jeweils konstant bzw. annähernd konstant gehalten werden.The area ratio (area of the circular near parts / area of the circular ring-shaped distant part (s) from the center of the lens in radial weighting towards the edge of the lens constant or be kept approximately constant.
Bei der Erfindung wird beim Öffnen der Pupillc die davor lieende Kontaktlinsenfläche zwar größer, jedoch bleibt das Verhältnis der relevanten Flachen (Fläche des Nahteil/Fläche des Fernteils), die für das Nah- und Fernsehen verantwortlich sind, zumindest annähernd konstant. Auf diese Weise wird bei raschem Hell-Dunkel-Wechsel die beibekannten konzentrischen Bifokallinsen vom bivisuellen Typ vorübergehend auftretende Visusminderung vermieden.In the invention, when the pupil is opened, the contact lens surface in front of it becomes although larger, the ratio of the relevant areas (area of the near part / area of the distant part), which are responsible for the local and television, at least approximately constant. In this way, when there is a rapid light-dark change, the one known Concentric bifocal lenses of the bivisual type temporarily occurring visual impairment avoided.
In der beiliegenden Figur ist schematisch ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment is shown schematically in the accompanying figure of the invention shown.
Die in der Figur schematisch dargestellte Linse besitzt in der Linsnmitte einen Fernteil mit der Fläche F1, der konzentrisch umgeben ist von einem Nahteil mit Kreisringfläche N1. Konzentrisch um diese schließen sich, in radialer Richtung zum Linsenrand hin gesehen, weitere Fernteile mit den Flächen F und F sowie Nahteile mit den Flächen 2 3 N und N an.The lens shown schematically in the figure has the lens center a distance part with the area F1, which is concentrically surrounded by a near part with circular ring area N1. Concentrically around these close in a radial direction Looking towards the edge of the lens, further distant parts with areas F and F as well as near parts with the areas 2 3 N and N.
2 3 Fr den Fall, daß F /N = F + F /N + N = F + F + F / 1 1 1 2 1 2 1 2 3 # + N + N = 1 ist, 1 2 3 sind alle Kreisringflächen gleich groß, d. h. die Radien der Kreise sind tl s In der folgenden Tabelle 1 sind in mm mit B1 der Durchmesser des in der Linsenmitte liegenden Fernteils und mit B2 bis B6 die Breiten der konzentrisch dazu liegenden sich abwechselnden kreisringförmigen Nah- und Fernteile angegeben.2 3 For the case that F / N = F + F / N + N = F + F + F / 1 1 1 2 1 2 1 2 3 # + N + N = 1, 1 2 3 all annulus areas are the same large, i.e. the radii of the circles are tl s In the following table 1 the diameter of the distant part lying in the center of the lens is indicated in mm with B1 and with B2 to B6 the widths of the concentric, alternating circular near and distant parts.
In der nachfolgenden Tabelle 2 sind mit r der Radius der Kreisflächen des in der Linsenmitte liegenden Kernteils und mit r2 bis r6 die Radien der Zonenübergänge zwischen den konzentrischen kreisringförmigen Nah- und Fernteilen in mn angegeben.In Table 2 below, r is the radius of the circular areas of the core part lying in the middle of the lens and with r2 to r6 the radii of the zone transitions between the concentric circular near and far parts given in mn.
