Rod cells are highly light-sensitive and function best in low light conditions, allowing us to see in dimly lit environments. They are responsible for black and white vision and do not provide high-acuity color vision. Rod cells are more numerous than cone cells in the human retina and are not evenly distributed, being more concentrated in the peripheral retina.
