Brightness adaptation is the process by which the human visual system adjusts to changes in light levels in the environment. This adjustment allows the eyes to remain sensitive to a wide range of illumination, enabling us to see clearly in both bright and dim conditions. It involves physiological changes in the retina, such as the regeneration of photopigments and alterations in the sensitivity of photoreceptors. This adaptation can take seconds to minutes, depending on the extent of the light change.
