Red-green color blindness is a common vision deficiency that affects the ability to distinguish between red and green hues. This condition occurs when the cones in the retina, responsible for detecting these colors, do not function properly. It is often inherited and more prevalent in males than females. People with red-green color blindness may confuse colors like red and brown or green and beige. This can impact daily activities, such as reading traffic lights or choosing clothing. While there is no cure, many individuals adapt by using color-coded systems or special glasses to help differentiate colors more effectively.
