In the human eye, the distribution of rods and cones varies. The concentration of rods increases as you move from the center to the periphery of the retina. On the other hand, the concentration of cones increases as you move from the periphery to the center where the macula lutea and fovea centralis are located. If you compare the functions of rods and cones, how do you account for the different distribution patterns of these cells?

Madhur L.
Which of the following is true about the difference between the rods and the cones? The rods are packed in an area called the fovea, and the cones are found more in the peripheral retina. The only difference between the rods and the cones is physical shape. There are about 120 million rods in the human eye and about 6 million cones. The rods control vision in high illumination conditions, and the cones control vision in low illumination conditions.
