Dyschromatopsia, commonly known as color vision deficiency, is a condition characterized by the inability to perceive colors in a normal way. It results from a malfunction in the cone cells of the retina, which are responsible for color detection. Different types exist, impacting the perception of red, green, or blue hues. The severity varies from mild color confusion to complete absence of color vision (achromatopsia). While often inherited, it can also arise from eye diseases, injuries, or certain medications, affecting everyday activities like choosing ripe produce or interpreting traffic signals. This condition highlights the complexity of human vision and its susceptibility to biological variations.
