WebMay 23, 2024 · Cone cells, or cones, are photoreceptor cells in the retina of the eye that are responsible forcolor vision; they function best in relatively bright light, as opposed to rod cells that work better in dim light. Cone cells are densely packed in the fovea, but gradually become sparser towards the periphery of the retina. WebRods and cones are two types of photoreceptors in the eye. Both are specialized nerves that convert light into neural impulses, but they differ in number, location, and function. Rods are more numerous, located in the periphery of the eye, and good for detecting light in general. Cones are concentrated near the fovea, responsible for color ...
