No. Your eyes are just adapting to the darkness.
Our eyes are highly adaptive to different lighting conditions. You may know that the pupil (the black part in the centre of your eye that lets light in) expands in dim light to let more light in, but this is not the end of the story by any means.
Our eye detects light by a chemical process, involving the protein molecule rhodopsin, which exists in the rod and cone cells which line the retina at the back of the eye. When exposed to light, rhodopsin does two things:
On the other hand, in dim light, most of the rhodopsin molecules have time to relax back into their active state before more photons arrive, so that now most of the rhodopsin in your eye is in the active state, awaiting more photons to detect. In other words, your eyes become more sensitive to light when the light is dimmer. Which is exactly what you want.
This process of the amount of rhodopsin molecules in an active light-receiving state in your eye being controlled by the amount of incoming light is known as adaptation. And because the rhodopsin takes a few minutes to return to the active state, this produces the familiar time lag of a few minutes when you go from a brightly lit area to a dark one, in which your eyes are "adjusting" to the dark.
Biochemistry is cool.
