Wikipedia
Scotopic vision
In the study of human visual perception, scotopic vision (or scotopia) is the vision of the eye under low-light conditions. The term comes from Greek skotos, meaning "darkness", and -opia, meaning "a condition of sight". In the human eye, cone cells are nonfunctional in low visible light. Scotopic vision is produced exclusively through rod cells, which are most sensitive to wavelengths of around 498 nm (blue-green) and are insensitive to wavelengths longer than about 640 nm (red-orange). This condition is called the Purkinje effect.

scotopic vision
Scotopic vision is a type of vision that is sensitive to low light conditions and is primarily provided by rod cells in the eyes which are sensitive to low light but not color variations. It's often referred to as night vision or twilight vision. This form of vision is most effective in dim light or at night.

Scotopic vision
Scotopic vision is the vision of the eye under low light conditions. The term comes from Greek skotos meaning darkness and -opia meaning a condition of sight. In the human eye cone cells are nonfunctional in low light – scotopic vision is produced exclusively through rod cells which are most sensitive to wavelengths of light around 498 nm and are insensitive to wavelengths longer than about 640 nm. Scotopic vision occurs at luminance levels of 10−2 to 10−6 cd/m². Other species are not universally color blind in low-light conditions. The Elephant Hawk-moth displays advanced color discrimination even in dim starlight. Mesopic vision occurs in intermediate lighting conditions and is effectively a combination of scotopic and photopic vision. This however gives inaccurate visual acuity and color discrimination. In normal light, the vision of cone cells dominates and is photopic vision. There is good visual acuity and color discrimination. In scientific literature, one occasionally encounters the term scotopic lux which corresponds to photopic lux, but uses instead the scotopic visibility weighting function.
