Rods are used for low-light contrasts, unlike cones which detect colour. They are photoreceptive cells found in the retina. Rods function in less intense light than cones, and are involved in peripheral vision.

Rods detect low levels of light, specifically dim light and movement in our peripheral vision. They are responsible for our night vision and are highly sensitive to light, allowing us to see in low-light conditions.
Rod cells do not detect color. They are responsible for detecting low levels of light and are more sensitive to brightness and contrast rather than color. Cone cells, on the other hand, are responsible for detecting color.
The retinal receptors responsible for detecting black, white, and gray colors are the rods. Rods are highly sensitive to light and function well in low light conditions, making them crucial for night vision. They do not contribute much to color vision but are essential for detecting differences in light intensity.
The cells in the retina of the eye that detect light are called photoreceptors. There are two types of photoreceptors: rods, which are responsible for vision in low light conditions, and cones, which are responsible for color vision and visual acuity in bright light.
The nerves that transmit messages from the rods and cones are called optic nerves. Rods and cones are specialized cells in the retina of the eye that detect light and convert it into electrical signals. These signals are then transmitted through the optic nerves to the brain, where they are processed and interpreted as visual information.
Both rods and cones are light receptors. Rods are connected many to onr neuron, and are good for detecting low-light and movement, but not color. Cones are one to a neuron and detect color. Both are present in most if not all mammals and avians.
