Photopic vision is the vision of the eye under well-lit conditions (luminance levels from 10 to 108 cd/m2). In humans and many other animals, photopic...

luminous efficiency function generally refers to the photopic luminous efficiency function. The CIE photopic luminous efficiency function y(λ) or V(λ) is a...

Higher visual perception occurs under scotopic vision as it does under photopic vision. Of the two types of photoreceptor cells in the retina, rods dominate...

transition zone in dim conditions, between photopic and scotopic, where both cones and rods are active.) Photopic luminous efficacy of radiation has a maximum...

Mesopic vision, sometimes also called twilight vision, is a combination of photopic and scotopic vision under low-light (but not necessarily dark) conditions...

and that of the opsins in the longer-wavelength cones that dominate in photopic vision, about 555 nanometres (2.19×10−5 in) (green). In visual astronomy...

different wavelengths within the spectrum. When adapted for bright conditions (photopic vision), the eye is most sensitive to yellow-green light at 555 nm. Light...

conditions, is most sensitive near this frequency. Under these conditions, photopic vision dominates the visual perception of our eyes over the scotopic vision...

human brightness sensitivity. Typically, this weighting function is the photopic sensitivity function, although the scotopic function or other functions...

there is a separate function for each of two visual systems, one for photopic vision, used in daylight, which is mediated by cone cells, and one for...

dim-light scotopic vision and cones are primarily responsible for day-light photopic vision. For all known vertebrates, scotopic vision is monochromatic, since...

scotopic visual system, which is active in dim light. The cones enable the photopic visual system, which is active in bright light. While one is active, the...

performed perimetry test uses white stimuli on a bright white background (photopic white-on-white testing). This tests isolated L- and M-cone function and...

color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which work better in dim light, or the...

troland typically refers to the ordinary or photopic troland, which is defined in terms of the photopic luminance: T = L × p {\displaystyle \mathrm {T}...

lens. Their retinas generally have both rods and cones (for scotopic and photopic vision); many species have colour vision, often with three types of cone...

perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision),...
