Scotopic vision refers to the type of vision that occurs in low light conditions, primarily using rod cells in the retina, which are more sensitive to light but do not detect color or detail as effectively as cone cells, which are responsible for photopic vision in well-lit conditions. This type of vision is essential for night vision and allows for the perception of shapes and movement in dim environments, but it results in reduced visual acuity and detail.

In contrast, peripheral vision and photopic vision occur in brighter conditions, where more light is present, allowing for higher detail and color perception. Mesopic vision represents an intermediate state between photopic and scotopic vision, where both rod and cone cells function, typically during twilight. Therefore, scotopic vision is correctly identified for its primary role in low light scenarios, accurately explaining the reduced detail and acuity associated with it.
