What Are The Types Of Photoreceptors And Their Functions. The visual pigment consists of a protein called opsin and a chromophore derived from vitamin A known as retinal. Cone photoreceptors are morphologically and functionally distinct from rods and express several types of visual pigments or opsins whose spectral sensitivity varies based on the cones subtype. The central fovea is populated exclusively by cones. These properties reflect the fact that the rod and cone systems the receptors and their connections within the retina are specialized for.
