Sensitivity of human eye
WebThe human visual system manages to provide a usable signal over a broad range of light intensities. However, some eyes are better adapted optically to dealing with light or dark conditions. For example, the superposition eyes of nocturnal moths may be as much as a thousand times more sensitive than the apposition eyes of diurnal butterflies. Within … WebCone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes including the human eye. They respond differently to light of different wavelengths, and the combination of their responses is responsible for color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which ...
