12. Tritanopia is Blue/Yellow Color Blindness
Tritanopia is a medical term describing blue/yellow color blindness. However, individuals affected by this type of color blindness experience problems distinguishing between blue, yellow, and violet colors. Therefore, we think blue-green color blindness would be a better way of describing this condition. Defects in the Tritan affect your S-Cone “short-wavelength cone.” As a result, there are two ways this defect expresses itself in vision.
Tritanopia – Individuals affected by tritanopia are known as “dichromats.” These individuals are completely missing the S-cone, and they only have medium-wavelength cones.
Tritanomaly – With this form of the anomaly, the S-Cones have a mutation, and it’s very rare, affecting only one in 10,000 people. Unlike the traditional forms of red-green color blindness, Tritan defects come encoded on the 7-chromosome.
