Which type of vision do rods primarily provide?

Rods are photoreceptor cells located in the retina that are highly sensitive to light, making them crucial for night vision and vision in dimly lit environments. They do not detect color and are not involved in high-resolution vision; instead, they are responsible for peripheral and twilight vision. This sensitivity allows rods to contribute effectively to our ability to see in low-light conditions, such as at dusk or in dark rooms. Their main role is to enable vision when levels of light are too low for cone cells, which are responsible for high-resolution and color vision, to function optimally. Consequently, the correct answer reflects the primary function of rods in enabling vision under low-light conditions.
