scotopic
This is a technical term used almost exclusively in scientific, medical, and academic contexts, specifically within ophthalmology and visual science. It is not used in casual conversation; a layperson would simply say "night vision" or "seeing in the dark."
In a professional context, it is used to describe the specific physiological process where the rod cells of the retina are active, which occurs in very low-light environments. Because rod cells do not perceive color, scotopic vision is inherently monochromatic.
It is most frequently contrasted with photopic vision (vision in bright light using cone cells) and mesopic vision (the intermediate state where both rods and cones are active). Using "scotopic" in a non-scientific setting would be perceived as overly formal or pedantic.
