SeeKey
Proposal for SeeKey, an invention for the colour-blind to distinguish the colours red and green. The Seekey consists of two coloured filters with specially selected colours. As you look at something through one of the filters, the impression of the colour will change in a specific way. Assisted by the instructions for use provided with each Seekey, you will easily learn to interpret the change of colour, and, in this way tell what colour it is.
Navigational aid
As many as 8% of all men and 0.5% of all women, ie. 350,000 Swedes are red-green color blind. They have difficulty detecting beacons in the distance, distinguishing between the red and green markings and determining the color of lanterns, buoys and lighthouse sectors. They also have difficulty finding and distinguishing lines and symbols in the charts.
