RotGrünFarbsehstörung

RotGrünFarbsehstörung, commonly known as red-green color blindness, is the most prevalent form of inherited color vision deficiency. It affects a person's ability to distinguish between shades of red and green. This condition is significantly more common in males than in females, a pattern linked to the genetics of color vision, which is tied to the X chromosome. There are several subtypes of red-green color blindness, including deuteranopia (a defect in green cones), protanopia (a defect in red cones), and their less severe forms, deuteranomaly and protanomaly, where the cones are present but function abnormally. Individuals with these conditions may perceive red and green as similar colors, often appearing as muted brown or gray. The severity can vary, with some experiencing only minor difficulty distinguishing certain shades, while others have a more pronounced deficiency. This condition is usually congenital, meaning it is present from birth, and is not typically acquired later in life. Diagnosis is often made through standardized color vision tests, such as the Ishihara plates. While there is no cure for inherited red-green color blindness, specialized lenses can sometimes help improve color discrimination in certain situations, though they do not restore normal color vision.
