They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels ( photopic vision ), are capable of color vision and are responsible for high spatial acuity. WebRods, found in greater numbers than cones, are located across the entire retinal surface. There is a higher concentration of rods around the periphery (edges) of the retina, which allows you to see what is above, below and to the sides of the object you are directly viewing.
