What is Dark adaptation?Dark adaptation, thus, refers to the process by which, after exposure to strong light, the eye regains its sensitivity in the dark. Aubert was the first to calculate the threshold stimulation of the eye in the dark in 1865 by calculating the electrical current required to just barely make the glow on a platinum wire visible.
After being exposed to light, a process known as dark adaptation causes our eyes to adjust to darkness. When going from a bright, sunny environment outside to a rather dark interior setting, for example, it can be difficult to see at first. But as time goes on, our eyes recover and get more sensitive to the dim interior light.
Thus, option B is correct.
