WebRods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cone cells, or cones, are of three types of photoreceptor cells in the retina of mammalian eyes (e.g. the human eye). WebDark adaptation. Dark adaptation is essentially the reverse of light adaptation. It occurs when going from a well light area to a dark area. Initially blackness is seen because our cones cease functioning in low …
