Scotopic vision is a term used to describe the low-light conditions where the human eye can perceive only limited color and detail. There are several synonyms for scotopic vision, including "night vision", "rod vision", and "mesopic vision". The term "night vision" is commonly used in military applications, whereas "rod vision" refers to the sensitivity of the retina's rod cells that allow for visual perception in low light conditions. "Mesopic vision" is a term that describes the transition between the scotopic and photopic vision; it is the range where both rod and cone cells are activated. Overall, these synonyms for scotopic vision highlight the visual perception under low light and various contexts in which they occur.
