Rod cells, or rods, are photoreceptor cells in the retina of the eye that can function in less intense light than can the other type of photoreceptor, cone cells. Because they are more light sensitive, rods are responsible for night vision.What is the main function of the rods in the eye?
Rod, one of two types of photoreceptive cells in the retina of the eye in vertebrate animals. Rod cells function as specialized neurons that convert visual stimuli in the form of photons (particles of light) into chemical and electrical stimuli that can be processed by the central nervous system.How many rods does a human eye have?
There are approximately 120 million rods and 6 million cones in the eye. Rods are active for vision at night and cones are for daylight and colour reception.
