Red-green color blindness is a common visual impairment that affects the ability to distinguish between red and green hues. It occurs when the cones in the retina, which are responsible for color vision, do not function properly. This condition can make it difficult for individuals to identify certain colors, leading to confusion in everyday situations, such as interpreting traffic lights or choosing ripe fruits. There are two main types of red-green color blindness: protanopia, which affects red sensitivity, and deuteranopia, which affects green sensitivity. Both types are inherited and are more prevalent in males than females. While there is no cure, many people adapt by using color-coded systems or special glasses to help differentiate colors.
