photopic vision
Photopic vision is the vision of the eye under well-lit conditions, which allows for color perception and sharp details. It primarily involves the retina's cone cells and is responsible for our daytime vision. Photopic vision operates at luminance levels where the cones become highly active and, in humans, it is generally considered to be active at luminance levels over about 3 candela per square meter.

Photopic vision
Photopic vision is the vision of the eye under well-lit conditions. In humans and many other animals, photopic vision allows color perception, mediated by cone cells, and a significantly higher visual acuity and temporal resolution than available with scotopic vision. The human eye uses three types of cones to sense light in three bands of color. The biological pigments of the cones have maximum absorption values at wavelengths of about 420 nm, 534 nm, resp. 564 nm. Their sensitivity ranges overlap to provide vision throughout the visible spectrum. The maximum efficacy is 683 lm/W at a wavelength of 555 nm. The wavelengths for when you are in photopic vary with the intensity of light. For the blue-green region, 50% of the light reaches the image point of the retina. Adaptation is much faster under photopic vision. Adaptation can occur in 5 minutes for photopic vision but it can take 30 minutes to transition from photopic to scotopic. Most older adults lose photopic spatial contrast sensitivity. Older adults in their 70s require about three times for more contrast to detect high spatial frequencies than young adults in their 20s.
