What function do rods serve in the eye?

Rods serve a crucial role in our vision, particularly in low-light conditions. They are photoreceptor cells located in the retina and are highly sensitive to light, which allows them to function effectively in dim environments. Their primary function is to provide peripheral vision and to detect movement, but they do not detect color, as this is the role of cone cells, which are responsible for color vision and function well under brighter light conditions.

In summary, the primary function of rods is to enhance our ability to see in low-light environments while contributing to peripheral vision. This makes them vital for night vision, as they allow us to detect shapes and movements in less illuminated surroundings, which is especially important for survival in nature.
