The main function of rods and cones in the visual system is to convert light into electrochemical impulses that are sent to the brain through the optic nerve. This process is known as phototransduction and allows us to perceive visual information about the world around us. Rods are responsible for our ability to see in low light conditions and provide us with black-and-white vision, while cones allow us to see color and operate best in brighter light.
