tritanopia
Quick Summary
Tritanopia is a form of color blindness where individuals are unable to distinguish between blue and yellow colors. This condition arises when the blue cones in the retina are absent or non-functional. As a result, people with tritanopia perceive only shades of red and green. This is distinct from red-green color blindness, which involves the absence or malfunction of red or green cones. Tritanopia is an autosomal dominant disorder, meaning it can be inherited from either parent. While often congenital, it can also be acquired due to certain diseases or medications.12
