Summary: | The device has a correction lens diminishing better perceived wavelengths by a suitable filter glass and increasingly passing-through weakly perceived wavelengths in relation to the better perceived wavelengths during the viewing of a person. The correction lens is formed by an eyeglass lens or a contact lens. The filter glass balances the individual colour falsification of a person with colour vision deficiency. An independent claim is also included for a method for correcting the colour vision deficiency of a person.
Die Erfindung betrifft eine Vorrichtung zur Korrektur von Farbsinnstörungen und ein Verfahren zu ihrer Anwendung. Die Vorrichtung weist eine Korrektionsoptik auf, mittels welcher durch geeignete Filter die Wellenlängen, die besser wahrgenommen werden, abgeschwächt und somit die Wellenlängen, die schwächer wahrgenommen werden, im Verhältnis dazu vermehrt durchgelassen und dem Auge farbstärker angeboten werden. Das Verfahren besteht darin, die individuelle Farbsinnstörung zu messen und durch geeignete Filtergläser die individuellen Farbverfälschungen auszugleichen. |
