Ishihara test: used to identify color blindness

What is - definition

Color blindness is most often a change of genetic origin where the individual is unable to identify colors. A very common feature of this disorder is the great difficulty that its carriers have in differentiating green from red.

Information and characteristics of color blindness

Name origin

John Dalton was the first scientist to study this disorder, since he himself was the carrier of this visual alteration. In honor of this chemist, this difficulty in color perception has come to be called color blindness.

More common in men

Directly related to the X chromosome, this "visual dysfunction" is far more common in men than in women. It is believed that 8% of the population has this disorder, within this percentage, only 1% includes women, the remaining 7% include males.

Advantages over non-colorblind people

The genetic mutation that causes color blindness gives the color-blind some advantages such as a much sharper night vision in relation to those who do not have it, and also a greater ability to recognize semi-cultic elements that would go unnoticed for non-color-blind people.

No treatments yet

There are currently no treatments for this disorder; however, being aware of their visual limitations, a person with color blindness can adjust to them and lead a normal life.
