Why Compensating Color Vision Deficiency (CVD) is Important?
Vision is the most important human sensor: 90% of all information received is via vision, 5% via hearing, 2% touching, 2% tasting, 1% smelling. The loss of information due to inadequate color decoding prevents or slows down comprehension, increases reaction time and generally lowers the quality of life. Normal color vision individuals are able to distinguish more than a million different shades of colors. Meanwhile an average color vision deficient person only a couple of thousands and a more serious patient only a few hundreds. This may result that a CVD person does not realize if his partner blushes or gets pale during a conversation, cannot notice if a child has fever just by his face color, cannot distinguish between ripe and unripe fruits etc. notices disadvantages in almost all areas of life compared to people with normal vision.
