Types of Color Vision Deficiency

The various types of color vision deficiency, including protan, deutan, and tritan defects, play a crucial role in impacting an individual's perception of specific colors. These deficiencies stem from abnormalities in the cone cells of the retina, affecting the ability to distinguish certain hues.

  1. Protan (Red-Blindness): Individuals with protan defects have difficulty seeing red colors due to the lack of sensitivity in the red cone cells. This deficiency can lead to challenges in distinguishing red hues from green ones.
  2. Deutan (Green-Blindness): Deutan defects affect the perception of green colors, making it hard for individuals to differentiate between green and red shades. This deficiency is a result of anomalies in the green cone cells in the retina.
  3. Tritan (Blue-Yellow Color Blindness): Tritan defects impact the ability to differentiate blue and yellow hues. This deficiency is rare compared to protan and deutan deficiencies and is caused by anomalies in the blue cone cells of the retina.
