WebCone cells, or cones, are of three types of photoreceptor cells in the retina of mammalian eyes (e.g. the human eye). They are responsible for color vision and function best in relatively bright light, as opposed to rod cells, which work better in dim light. Suggest Corrections. 12. WebFeb 4, 2024 · Cones are cone shaped structures and are required for bright light (day light) vision. Rods are rod like structures located through the retina except for the fovea, and are required for dim light (twilight/night) vision.
