What type of light are rods primarily sensitive to?

Rods are specialized photoreceptor cells in the retina that are highly sensitive to light, particularly in low light conditions. Their primary role is to enable vision at dusk or in dimly lit environments, allowing us to detect shapes and movements. Rods contain a pigment called rhodopsin, which is particularly effective in low light, making them crucial for night vision.

Unlike cones, which are responsible for color vision and function best in bright light, rods do not require bright conditions to operate effectively. This sensitivity to low light enables us to perceive images even when light is scarce, demonstrating the vital role rods play in both peripheral and night vision.
