Question

Quizplus · Accepted Answer

The threshold for vision refers to the minimum amount of stimulation required for a sensation to be detected. Adaptation is the process by which our sensitivity to stimuli decreases over time as we become accustomed to them. In the case of vision, adaptation means that after being exposed to bright sunlight for a period of time, our threshold for vision is higher, meaning it takes more light to stimulate our visual receptors. Conversely, in a dark moonless night, our eyes adapt to the low light levels, and our threshold for vision is lower, meaning we can detect even very faint sources of light.
