WebRods are sensitive to vision in low light and do not sense the color of light, whereas cones are sensitive to brighter light and allow us to perceive color in normal lighting. Figure 36.17 (a) The human eye is shown in cross section. (b) A blowup shows the layers of the retina. 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.
