tritanomaly
Tritanomaly describes a partial deficiency in the blue-cone photoreceptors, meaning the individual can still perceive blue light but with reduced sensitivity. This differs from tritanopia, which is a total absence of blue-cone function. Because it is a clinical condition, the term is primarily used in medical, optometric, and scientific registers.
As a medical diagnosis referring to a specific physiological state, the term is treated as an uncountable noun. It describes a condition rather than a discrete object that can be counted.
Meanings

The patient was diagnosed with tritanomaly, which made it difficult for him to perceive certain shades of blue.
