WebThere are two types of photoreceptors in the human retina, rods and cones. Rods 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. WebHighly sensitive rods allow us to see at very low light levels – but in shades of gray.
