IPA: //fəʊˈtɒpɪk//
KK: /fōˈtäpik/
Relating to vision that occurs in bright light, particularly when the eyes are adapted to such conditions, and primarily involves the cone cells in the retina.
The photopic vision allows us to see colors clearly during the day.
Photopic → It is formed from "photo-" (from Greek "phōs", meaning light) and "-pic" (from Greek "opsis", meaning vision or sight). The word "photopic" refers to vision in well-lit conditions, emphasizing the role of light in sight.
Think of 'light' ('photo-') being essential for 'vision' ('-pic') — that's why photopic relates to seeing in bright light.
