Color blindness: do we all see the same color?

Dr. Gonzalez Costea is a renowned specialist in Ophthalmology in Murcia. He is an expert in the treatment of pathologies that affect vision. In this article the doctor explains what color blindness consists of, a pathology that affects men to a greater extent and has no treatment.

The diagnosis of color blindness or color blindness, although relatively easy to detect, often goes unnoticed for many years and only becomes apparent with the performance of a test or analysis.

What is color blindness

It is not really possible to know how each person sees, a clear example is the case of the famous dress that spread on networks some time ago. Some users perceived it as white and gold, while others saw it as blue and black. What can be known are the defects in vision in certain people or those who do not see a certain color, who suffer from color blindness or color blindness.

The justification for color blindness is the genetic alteration of the receptors that affects about 8 or 10% of men. And in women about 0.5%. It is known to be a genetic defect associated with the X chromosome. Males have the XY chromosome, so they are more predisposed to develop color blindness on the X chromosome. Women, on the other hand, have the XX chromosome, so if they do not develop color blindness on one, they cannot develop it on the other.

Color blindness has no treatment

It is a genetic pathology that comes from birth, it cannot be acquired over the years. Although there may be alterations in vision in adulthood, but they are usually caused by drugs or pathologies affecting the retina, but it is not considered color blindness.

The most common color blindness is red-green, which is associated with the X chromosome. But there is also one for blue-yellow, which affects males and females equally and is found on chromosome 7.

Treatment for color blindness

This pathology has no treatment. There are various degrees of color blindness, some mild and others more severe, such as chromatopsia, in which patients with color blindness do not have any of the three receptors that a person with normal vision usually has: red, green and blue.

When all three receptors are affected, these people see in gray color and there is no type of glasses or treatment that allows them to see any color. There are a series of alterations in which the three receptors are fine but some of them do not work with full acuity, so that these people with the use of a filter can get to shade the colors, but they will never see correctly.
