Tritan Color Blindness

What is a Tritan color blindness? Reduced color discrimination of shades of blue and yellow is called Tritanomaly, or Tritanopia. Tritanomaly, causing reduced blue sensitivity and Tritanopia, resulting in no blue sensitivity, can be inherited or acquired; the inherited form is a rare autosomal recessive condition. More commonly, Tritanomaly is acquired later in life due to age-related or environmental factors. Cataracts, glaucoma and age related macular degeneration could cause someone to test as a Tritan. People with tritanomaly have reduced sensitivity in their blue “S” cone cells, which can cause confusion between blue versus green and red from purple. If you believe you have Tritanomaly, we recommend you consult with an eye care professional for a complete vision assessment.

Tritanomaly and Tritanopia color blindness is not a type of what is commonly referred to as red-green color blindness, but is also a form of color vision deficiency. EnChroma glasses are designed to address forms of red-green color blindness and are not intended to assist the vision of people with Tritan-type deficiency.
