Cones and rods

Cones and rods are specialized cells in the retina of your eye that help you see. Rods are highly sensitive to light, allowing you to see in low-light conditions, but they do not detect color. Cones function best in bright light and are responsible for color perception and sharp central vision. Together, these cells enable you to see clearly across different lighting environments and perceive a full range of colors. The balance between rods and cones varies across the retina, with cones concentrated in the central part (fovea) for detailed color vision, and rods more numerous on the periphery for vision in dim light.
