A color blind person does not see only in black and white, did you know? If the answer is no and you want to know more about this vision disorder, this article will help you … Definition, causes, treatments, let’s enter the world of color blindness.

 

What is color blindness?

 

Color blindness is a color vision disorder that is in fact hereditary. Indeed, there are several forms of color blindness including:

 

  • Those who have trouble distinguishing between red and green are the most popular form of color blindness.
  • Blue color blindness or monochromatism (where the person distinguishes only black, white and gray) are much rarer forms.
  • There is also semi-color blindness which is not as disturbing as color blindness.

 

Note that people of Asian or African descent are much less likely to suffer from color blindness. On the other hand, men are more likely to develop color blindness. The latter have only an X chromosome, and if the latter is damaged, color blindness can occur. As for women, they have two X chromosomes. Therefore, even if one of its chromosomes is damaged, the other can compensate for the functioning of the other. Also be aware that a woman who has a colorblind chromosome can actually pass it on to her child at birth.

 

Color blindness, what is the cause?

 

The retina of the eye has 3 cones that are sensitive to light. These cones are divided into 3 categories, including a cone that distinguishes red, another green and the last blue. If a cone does not work properly, this is where the problem arises, that is, the person will not perceive the color of the cone which does not work.

 

Color blindness is hereditary in most cases. However, in some cases, color blindness can be the result of an illness, such as that of the retina, an injury or a side effect due to taking medication.

 

Symptoms and complications

 

Color blindness can vary and be moderate to very strong. As a result, a color blind person will not realize his illness so quickly, unless his entourage notices. If you wear socks of different colors but you do not notice this difference, you can imagine, you should consult!

 

Be aware that a person with severe color blindness in green, for example, will not differentiate between red, brown, green, orange, and light red. If he has red color blindness, all the shades of red will appear very dull.

 

On the other hand, blue color blindness is either hereditary or is due to taking drugs which had a severe impact, thus damaging the retina or the optic nerve.

 

 

In conclusion, if the vision disorder is hereditary, there is unfortunately no treatment. However, if this disorder is the cause of an injury or illness, your doctor can effectively treat it. In all cases, it is best to consult a specialist. Do you want to know more about this wonderful organ that is the eyes? You only have to consult our blog to know everything!
