The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision. In a dim room, however, we use mainly our rods, but we are ” color blind.” Rods are more numerous than cones in the periphery of the retina.
