Photopic vision is the vision of the eye under well-lit conditions (luminance level 10 to 10^8 cd/m^2), which allows for color perception and is mediated by cone cells in the eye.
Pronunciation
Pho·to·pic vi·sion: /fəʊˈtɒpɪk ˈvɪʒən/
Etymology
The term "photopic" comes from the Greek words "phōs" (φῶς), meaning "light", and "opsis" (ὄψις), meaning "sight".
Related Terms
- Scotopic vision: The vision of the eye under low-light conditions, mediated by rod cells in the eye.
- Mesopic vision: The vision of the eye under intermediate-light conditions, involving both rod cells and cone cells.
- Cone cells: One of the two types of photoreceptor cells in the retina of the eye, responsible for color vision and function best in relatively bright light.
- Rod cells: Photoreceptor cells in the retina of the eye that can function in less intense light than cone cells, but are not sensitive to color.
