DICHROMATIC VISION Meaning and
Definition
-
Dichromatic vision refers to a visual system present in certain organisms, including humans, that is characterized by the ability to perceive and distinguish between two primary colors or hues. This type of vision is commonly found in species that possess two types of color-sensitive photoreceptor cells, known as cones, in their eyes. The cones are responsible for detecting and transmitting information about different wavelengths of light, enabling the perception of colors.
In dichromatic vision, the two types of cones are sensitive to different regions of the light spectrum, typically corresponding to blue and green wavelengths. As a result, individuals with dichromatic vision are limited in their ability to discriminate between colors and perceive certain shades that can be distinguished by individuals with trichromatic (normal) vision.
An example of dichromatism in humans is red-green color blindness, a condition where there is a deficiency or absence of one type of cone, resulting in an inability to differentiate between certain shades of reds and greens. Dichromatic vision can also be observed in some animals, such as dogs, which have a limited color perception compared to humans.
Overall, dichromatic vision denotes a visual system that relies on the detection of only two primary colors, as opposed to trichromatic vision, which incorporates three primary colors to enable a wider range of color discrimination and perception.

Etymology of DICHROMATIC VISION
The word "dichromatic" is derived from the Greek words "di", meaning two, and "chroma", meaning color. It refers to the ability to perceive only two primary colors, usually blue and yellow, instead of the typical three primary colors, which includes red, green, and blue.
The word "vision" comes from the Latin word "visio", which means sight or the act of seeing. It involves the ability to detect and interpret visual stimuli through the eyes.
Therefore, "dichromatic vision" combines these two terms to describe the visual perception of the world using only two primary colors, indicating a specific type of color blindness.
