WebRods are extremely sensitive to light and are responsible for vision in dim light. This is called Scotopic vision. The role of cones in visual perception: Cones also contain visual pigments made up of retinene, which is combined with a protein opsin (photopsin). Three pigments each responding to different wavelength are found in man. WebNervous tissue that contains photoreceptors lies on this basement layer. The photoreceptors are called rod and cone cells because of their shape. Rods are sensitive to dim light, whereas cones respond to high-intensity light and are involved in colour perception.
