The luminosity of the human eye is not a fixed value, as it varies based on lighting conditions and individual sensitivity. However, the eye is most responsive to light intensities ranging from about 10^-6 to 10^3 lux. In terms of brightness perception, the human eye can detect light levels as low as 1 photon under optimal conditions. Overall, the eye's ability to perceive light is highly adaptable, allowing humans to see in a wide range of environments.
