WebRods deal with low light level and do not mediate color vision. Cones, on the other hand, can code the color of an image through comparison of the outputs of the three different types of cones. Each cone type responds … 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.

WebRods are responsible for vision at low light levels ( scotopic vision ). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels ( photopic vision ), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones. WebThe main function of the horizontal cells is to vary the extent of coupling between photoreceptors and between photoreceptors and bipolar cells. This provides a control system that keeps the activity of the bipolar cells …
