Colour vision deficiency isn’t a type of visual deficiency or blindness, yet it is an insufficiency in the way you see color. With this vision problem, you have problems identifying and distinguishing colors from each other, for example between yellow and red or between green and blue.
Colour vision deficiency is an inherited condition that affects more males than females. Red-green color deficiency is the most widely recognized type of colour vision deficiency.
An individual may acquire a trait that lessens the ability to see blue and yellow colors. This blue-yellow deficiency more often influences men and women equally.
Colour vision deficiency happens when light-sensitive cells in the retina do not react suitably to varieties in wavelengths of light that make individuals to see colors.
