when we are in bright sunlight, the iris of our eyes adjust the pupil in such a way that less light enter our eyes (Pupil shrinks).
in a dark room iris expands to enter maximum light. When we suddenly enter a dark room from bright sunlight iris need some time for expansion and to adjust with the less light condition.
