Scotopic vision is
WebCones subserve daylight or photopic vision, when pho-tons are abundant. Together with specially evolved neural circuitry, they are responsible for the percep-tion of fine temporal and spatial detail, and for colour vision. In contrast, rods mediate starlight–twilight or scotopic vision, when photons are few. Their design is Web18 Aug 2024 · 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". [1] In the human eye, cone cells are nonfunctional in low visible light. Scotopic vision is produced exclusively through rod ...

WebThese cells contain the light-sensitive proteins called the photopigments. The daylight (photopic) vision and color vision are functions of cones and. the twilight (scotopic) vision is the function of the rods. Hence Rods and cones cells helping in the vision under light and dark conditions. So, the correct answer is 'Rods and cones'.
