Color Blindness Test Result

Tritanomaly/Tritanopia

Tritan-type color blindness is characterized by a loss of color discrimination for shades of blue and yellow. This can be caused by age-related factors, genetic factors, as well as exposure to certain toxins such as mercury. A complete diagnosis of color vision deficiency is not possible using online testing–consult an eye care professional for more information.

EnChroma glasses are usually effective for red-green color blindness and are unlikely to help for tritanomaly or tritanopia (blue-yellow color blindness). However, if you would like to try EnChroma glasses, you can return them if they don’t work for you. All EnChroma products are satisfaction-guaranteed within 60 days of purchase.

Symptoms of Tritanomaly/Tritanopia

  • Color-Name Confusion

    Shades of blue, gray and green may appear confusingly similar. This could make “naming” the color difficult.  Blue and purple can also be confused.

  • Impaired Color Perception

    A human with normal color vision can see about 1 million distinct shades of color. For someone with color blindness, the appearance of certain color hues are reduced: on average they see between 5-10% of the color gamut. For persons with tritan-type deficiency, the loss mainly affects the “blue-yellow” axis of color space while leaving the “red-green” axis intact.

  • Age and Environmental Factors

    Tritan-type color vision deficiency can be an indicator of a yellowing of the lens.  Yellowing is correlated with the accumulated lifetime of sun exposure to your eyes.  Doctors recommend wearing good quality sunglasses as often as possible when outside.
