How many rods and cones are in the eye? Despite the fact that perception in typical daytime light levels is dominated by cone-mediated vision, the total number of rods in the human retina (91 million) far exceeds the number of cones (roughly 4.5 million). As a result, the density of rods is much greater than cones throughout most of the retina.
How many rods are in the human eye? They do not perceive colour and fine detail, tasks performed by the other major type of light-sensitive cell, the cone. Rod cells are much more sensitive to light than cones and are also much more numerous. The human eye contains about 130 million rods and about 7 million cones.
