Understanding What Is Color Blindness

Color blindness may be the difficulty faced by lots of people in identifying and recognizing different shades and colors. Usually in healthy people who have normal color vision (trichromats), you can find photoreceptors, referred to as cones which are concentrated at the heart of the retina, that have 3 various kinds of photosensitive pigments -- blue, green and red -- that allow differentiation and identification between different colors and shades. However, in a few individuals, the cones become dysfunctional because of the deficiency (anomalous trichromats) or complete absence (dichromat) of 1 or more of the photosensitive pigments. As a total result, the average person develops difficulty in differentiating between colors or recognizing them.

The extent of color blindness can vary greatly from mild to severe with partial color blindness allowing identification and differentiation between different colors such as for example blue and yellow. Those experiencing severe color blindness cannot differentiate between red, blue and green shades. But, those experiencing complete color blindness cannot identify any colors except shades of gray, black, and white. However, this kind of blindness connected with color is fairly rare and folks, that are completely color blind, are also suffering from other serious eye related problems invariably.

The outward symptoms of color blindness can vary greatly from individual to individual. Sometimes, the symptoms aren't very pronounced and the colour vision problem isn't so severe that the average person gets to find out about his disorder. Often, such those who are partially color blind might not realize that they're experiencing color blindness or they are seeing things differently from what seems to other folks with normal color vision. The worst part concerning this disorder is that there is absolutely no treatment or cure plan for it till date.
