What are the causes of Color Blindness?
Every day we can go out and see how the day will be or enjoy a beautiful landscape, however, there are people who have difficulties to be able to enjoy things as simple as that, because they have a distortion of colors.
People with color blindness have the difficulty described in the previous paragraph. Color blindness is a condition that makes it difficult to recognize some colors correctly. Its name comes from John Dalton, who was the first person known to suffer from this problem.
The human being is made up of 23 pairs of chromosomes of which is one only has the altered gene, then the man will suffer from this disorder. For a woman to be color-blind, she must inherit 2 affected X chromosomes. Because of this, the chances of a woman developing color blindness are very low but not impossible.
At present, 3 types of color blindness can be distinguished:
Dichromatism: In the eye there are cells called cones that are responsible for recognizing the different waves of blue, red and yellow. In people who have this type of color blindness, they only have 2 of the 3 existing types of cones, therefore they have problems recognizing the green color, in the event that the cone in charge of the red waves is missing, and vice versa.
In the event that the missing cone is the recognizer of the blue color, these people will have difficulties to recognize the yellow color and bluish tones.
Achromatopsia: This is the worst type of color blindness and the person who suffers from it can only recognize the gray scale.
Anomalous trichomatism: This type is the mildest since the individual has all three types of cones, only that they have some abnormalities that lead to their not working properly in their entirety.
Color blindness is a very serious issue that often leads to depression in the individual. It requires medical help and in some cases psychological assistance to be able to overcome the emotional problems that take place in the affected person.
