Abstract

Color Blindness is the decreased ability to see colors or differences in color and may make some educational activities more difficult. However, problems are generally minor, and most color-blind people adapt. People with total color blindness (Achromatopsia) may also be uncomfortable in bright environments and have decreased visual acuity. Color Blindness is typically an inherited genetic disorder most commonly X-linked recessive inheritance. This means that a woman who cares this gene has 50% possibility to transmit to his son and, if she has the illness, 100% possibility to transmit. In almost all cases people retain blueyellow discrimination, and most color-blind individuals are anomalous trichromats rather than complete dichromats (they often confuse red and green items).
