värinäköhäiriön
Värinäköhäiriö, commonly known as color blindness, is a condition characterized by the reduced ability to distinguish certain colors. It is most often hereditary, passed down through genes, and affects men more frequently than women. The most common form is red-green color blindness, where individuals have difficulty differentiating between red and green hues. Other types include blue-yellow color blindness and complete achromatopsia, a rare condition where individuals see only in shades of gray.

Diagnosis is usually made through various color vision tests, such as the Ishihara plates or the Farnsworth-Munsell
