Quizplus · Accepted Answer

The periphery of the retina has fewer cones, which are responsible for color vision, compared to the central part of the retina. This is because the periphery is mainly composed of rod cells, which are responsible for black and white vision and low-light vision. As a result, color vision is poor or absent in the periphery of the retina.
