The function of rods and cones is primarily associated with vision because these are the two types of photoreceptor cells located in the retina of the eye. Rods are responsible for vision in low-light conditions and enable us to see in dim lighting, while cones are responsible for color vision and visual acuity in brighter light. If rods and cones did not function properly, it would severely impact a person’s ability to see, distinguishing them as integral to our visual system. Other senses such as hearing, touch, and smell do not involve these photoreceptors, as they rely on entirely different sensory receptors and neural pathways dedicated to processing stimuli for those specific senses.
