Deuteranopia is a type of color blindness that affects the perception of green light. Individuals with this condition have difficulty distinguishing between green and red hues, as their eyes lack functioning cones that are sensitive to green wavelengths. This can lead to challenges in identifying colors in everyday situations, such as traffic lights or colored clothing. Deuteranopia is caused by a genetic mutation and is more common in males than females. It is one of several types of color vision deficiencies, which also include protanopia and tritanopia. While there is no cure, many people adapt by using color-coded systems or labels to help differentiate colors.
