rod photoreceptor

Rod photoreceptors are specialized cells in the retina of the eye that enable us to see in low light conditions. They are more sensitive to light than cone cells, which detect color. Rods don’t provide color vision, but they help us see shapes and movements in dim lighting, making them essential for night vision. Each eye contains about 120 million rod cells, primarily located around the edges of the retina. They work by converting light into electrical signals that are sent to the brain, allowing us to perceive our surroundings in various lighting conditions.
