Abstract

The invention refers to a device for use by persons with limited colour vision, consisting of at least two colour filters 1 and 2 made of a transparent material enabling such persons to distinguish between colours and to detect objects. The device is designed so that the edge lines of the said filters are partly adjoined 3 partly separated by a colourless part or a space 4.
