DICHROMASY Meaning and
Definition
-
Dichromasy, also known as dichromatism, is a term used in the field of color vision to describe a specific type of color deficiency in which an individual's ability to perceive colors is limited to only two primary colors. It is a form of color blindness that results from a deficiency or absence of one of the three types of cones in the retina of the eye.
In the standard trichromatic color vision system, the three types of cones are responsible for perceiving and distinguishing between different wavelengths of light, which are perceived as various colors. However, in individuals with dichromasy, there is a defect or absence of one of the three types of cones, typically either the red or green-sensitive cones. Consequently, their ability to perceive the full range of colors is reduced, and they can only differentiate between two primary colors effectively.
The two primary types of dichromasy are protanopia, where the red-sensitive cones are lacking or defective, and deuteranopia, where the green-sensitive cones are affected. These conditions can result in difficulties distinguishing between red and green colors, as well as perceiving certain shades and hues.
Dichromasy is a relatively common color vision deficiency, affecting a significant portion of the population, particularly males. It can impact various aspects of daily life, such as recognizing traffic lights, distinguishing between color-coded information, and appreciating the full range of colors in art. However, despite the limitation, individuals with dichromasy can still lead normal lives and adapt to living in a world primarily designed for trichromatic color vision.
