Rods and cones are the two types of photoreceptor cells in the retina, each serving specific functions in vision.
Rods and cones are the two types of photoreceptor cells in the retina. Rods are highly sensitive to light and are responsible for peripheral and nighttime vision, while cones are weakly photosensitive and play a role in daytime and color vision.
Rods are more numerous than cones and are essential for vision in low-light conditions, motion detection, and peripheral vision. On the other hand, cones are concentrated in the central region of the retina and provide color information and vision in bright light.
Both rods and cones work in coordination with other cells in the retina such as bipolar cells, ganglion cells, horizontal cells, and amacrine cells to process visual information and transmit signals to the brain through the optic nerve.
