Värivärejä

Värivärejä is a Finnish term that translates to "color disorders" or "color vision deficiencies." It refers to conditions where a person's ability to perceive color is impaired. The most common type is red-green color blindness, which makes it difficult to distinguish between shades of red and green. Less common is blue-yellow color blindness, affecting the perception of blue and yellow hues. Complete achromatopsia, or total color blindness, where an individual sees only in shades of gray, is extremely rare.

These conditions are typically inherited, with most forms being X-linked recessive, meaning they are more prevalent in males. Occasionally, color vision deficiencies can be acquired later in life due to medical conditions such as glaucoma, diabetes, or certain medications. Diagnosis is usually made through standardized color vision tests like the Ishihara plates. While inherited color blindness cannot be cured, various aids and strategies can help individuals manage their condition and adapt to their environment.
