What are the different types of color blindness?
Color blindness or lack of color vision is a condition of eye in which the affected person does not see the difference between colors. It does not necessarily refer only to an individual who is completely blind, which is someone who only sees in black and white. In humans, different types of color blindness can be found. Along with the overall color blindness, there are two other types of red and green blindness and blue and yellow color blindness. An individual with certain types of colored blindness can have either partial or overall blindness to this color.
To understand different types of color blindness, it is probably best to first realize what allows color vision. Simply put, retina, part of the eye that allows people to see, has rods and cones. Rods allow night vision and cones allow color vision. Each cone has a pigment sensitive to light that reacts to red, green or blue colors. Color blindness is caused by any shortcoming pigments.
An individual with a regular vision, also called trichromacy, has no pigment deficiencies and is therefore able to see red, green and blue. Someone with an incorrectly aligned pigment has unusual trichomacy, which means that it can see all three colors, but one of the colors looks weaker than it would be for a person with a regular vision. Dichromacy is when an individual can only see two of the three colors, usually due to the missing or serious problem with the associated pigment. In the end, it is said that a person who sees only one color has monochromacy.
As part of anomalous trichromacy, dichromacy and monochromacy, there are names for every lack of colors. The inability to see red, green or blue at full depth and brightness is called protanomias, deuteromomals and tritanomali. In the same spirit, it is not seen at all red, green or blue is called Protanopia, deuteranopia and tritanopia. For monochromacy is not called no colors is called tYpical monochromacy, while we see a very small color, is called atypical monochromacy.
Red, blue and green colors can be mixed to form new colors such as purple color. Because this is the case, it is not possible to see the real range of color or color at all, it affects the way the individual sees the world. For example, a person with a counterpart would see a weakened version of the red inside the purple object, so this object would seem blue than purple. Of the different types of color blindness, the most common blindness is red and green colors. Blue and yellow color blindness is rare and the overall blindness is even more rare.
Although a person with color blindness is generally capable of living a normal life, having this condition can hold it back in some areas, for example in obtaining certain jobs. Usually, color blindness is hereditary, and therefore the affected person does not know that the world is no difference. Sometimes the condition can be caused by other things such as illness and aging. Color blindness jE usually diagnosed using the ishihara color test.
