WebIn 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".

WebCone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes including the human eye. They respond differently to light of different wavelengths, and the combination of their responses is responsible for color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which ...

WebA luminous efficiency function or luminosity function represents the average spectral sensitivity of human visual perception of light.It is based on subjective judgements of which of a pair of different-colored lights is brighter, to describe relative sensitivity to light of different wavelengths.It is not an absolute reference to any particular individual, but is a … WebThe human visual system manages to provide a usable signal over a broad range of light intensities. However, some eyes are better adapted optically to dealing with light or dark conditions. For example, the superposition eyes of nocturnal moths may be as much as a thousand times more sensitive than the apposition eyes of diurnal butterflies. Within …

WebAbout the diagram In this context the term ‘sensitivity of the eye’ refers to the varying response of the rods and cones in the human eye to different wavelengths of light. The diagram illustrates the varying response of the eye to wavelengths between approximately 380 and 700 nanometres (nm). WebThe eye, after about 30 minutes in the dark, may become about 10,000 times more sensitive to light. Vision under these conditions is, moreover, characteristically different from what it is under ordinary daylight conditions.
