What type of vision is primarily associated with rods in the human eye?

Scotopic vision is primarily associated with rods in the human eye. Rods are photoreceptor cells that are highly sensitive to light and enable vision in low-light conditions. They do not provide color discrimination but are essential for night vision and for seeing in dimly lit environments. Scotopic vision allows individuals to perceive brightness and movement under these low-light conditions, primarily due to the function of rods, which are abundant in the peripheral regions of the retina.

Photopic vision, on the other hand, is associated with cones in the human eye, which function best in bright light and are responsible for color vision. Thus, the role of rods aligns closely with scotopic vision rather than the others, which pertain to different aspects of vision and light.
