Cone cells

Cone cells are specialized photoreceptor cells in the retina of the eye that enable color vision and function best in bright light. There are three types of cone cells, each sensitive to different wavelengths of light (red, green, and blue). When light hits these cells, it triggers a chemical reaction that sends signals to the brain, allowing us to perceive colors and fine details. Cone cells are essential for activities such as reading and recognizing colors, differentiating them from rod cells, which help us see in low-light conditions but do not detect color.
