Question

Quizplus · Accepted Answer

Joe has a color weakness, also known as red-green color blindness. This means that his eyes have difficulty distinguishing between red and green hues. He may see these colors differently or confuse them with other colors. This condition is fairly common and affects about 8% of men and 0.5% of women of Northern European descent. Option A is incorrect because Joe would not see reds and greens as gray, but rather as different shades of other colors. Option C is incorrect because red-green color blindness is actually the most common form of color blindness. Option D is incorrect because rods are responsible for vision in low light conditions, while cones are responsible for color vision.
