There are many people who have a story of sensory experience to share. This is true for each and every one. For some, this may be related to the deficiency in color vision. This only means that the color of perception is really different from what others see. This is said to be a severe form of deficiency and there are so many color blindness facts that a lot of people have to learn. Usually, individuals with color blindness are not aware of the difference among these colors. They do not realize this right ahead. But then, identifying it is going to happen because of the individuals around. To confirm, having the eyes tested on a laboratory or clinic is the answer.
Usually, color blindness may be inherited. This is brought by abnormal photopigments. The mentioned would have to be the molecules that function to detect the color everywhere. This is always in cone-shaped cell which is situated within the retina. There are instances when this is referred to as the cone cells. As for most humans, the genes are required so that the body would be creating photopigments. The defects in this way are the genes which are the ones that trigger the color blindness all the time.
As what has always been claimed, there are three main kinds of color blindness. These would always be based on the defects of photopigment. These would always respond to red light, blue and green. Most of the time, red-green color blindness is a common one. This is followed by that of blue-yellow color blindness. The complete absence of color vision is considered to be the total color blindness. This is rare. However, it may still be a problem.
There are instances when color blindness is brought by chemical or physical damage. This is directed towards the optic nerve and on other parts of the brain. These are all responsible in processing the color information. Usually, color vision also declines as age gets older. This transpired because of cataract. This is a yellow and clouding factor that sets on the eyes.
Who suffers color blindness?
With this, no one is exempted. Everyone may suffer from it and that is the truth. For men, it is almost 8 percent. As for women, it is 0.5 percent. This is listed most especially from those who come with their innate Northern European ancestry. This is the answer to the common form of color blindness which is always of red-green.
Men are the ones who are prone to color blindness because women do not have the same genes. This is usually linked with the presence of the X chromosome. Males have an X chromosome. For females though, there are two. When it comes to females, the only functional gene is said to be one. This is just enough so that the loss of the other may be compensated. This is a sort of inheritance which is patterned with the X-linked. This would always affect males.
