A photoreceptor cell which is capable of phototransduction, it is a specialized type of neuron found in the retina which converts light into signals which is capable of stimulating biological process. At present there are three types of photoreceptor cells in mammalian eyes: rods, cones, and photosensitive retinal ganglion cells. The information used by the visual system is contributed by the two classic photoreceptor cells called rods and cones to form a representation of the visual world, sight.
