What type of vision is associated with rods and used in low light?

The type of vision associated with rods and used in low light is scotopic vision. Rods are photoreceptor cells in the retina that are highly sensitive to light and enable vision in dim environments. They do not provide color discrimination, which is why scotopic vision is typically experienced in grayscale. This function is essential for seeing in low-light conditions, such as at nighttime or in dark rooms.

In contrast, central vision primarily relates to the use of cone cells, which are responsible for high acuity and color vision in well-lit conditions. Mesopic vision occurs in intermediate levels of light, where both rods and cones are active, and hence, it does not specifically emphasize the low light capability that rods provide. Photopic vision involves the functioning of cone cells and is associated with well-lit conditions where colors are distinguishable. Thus, scotopic vision accurately captures the essence of how rods facilitate sight in low-light scenarios.
