RotGrünStörungen

RotGrünStörungen, often translated as red-green color blindness, is a condition affecting an individual's ability to distinguish between shades of red and green. It is the most common type of inherited color vision deficiency, with its prevalence significantly higher in males than females. This genetic condition is X-linked, meaning the gene responsible for it is located on the X chromosome.

The root cause of RotGrünStörungen lies in a malfunction of the cone cells in the retina, specifically those responsible for detecting red and green light. There are three types of cone cells, each sensitive to different wavelengths of light: red, green, and blue. When one of these sets of cone cells is absent or not functioning correctly, it leads to a deficiency in color perception. In the case of red-green color blindness, either the red-sensitive cones (protanopia/protanomaly) or the green-sensitive cones (deuteranopia/deuteranomaly) are affected.

Individuals with this condition may see reds and greens as muted, brownish, or grayish. The severity can vary greatly, from a mild difficulty in distinguishing certain shades to a near absence of red-green perception. Diagnosis is typically made through various color vision tests, such as the Ishihara plates, which use patterns of colored dots. While there is no cure for inherited color blindness, specialized lenses and apps can sometimes assist in improving color discrimination.
