In bright light, the iris contracts the pupil of an eye to allow less light to enter the eye. When, we enter a dim-lit room, the iris takes time to expand the pupil of the eye to allow more light to enter it. Thus, for a short time one is unable to see in a dim-lit room.

Answer:

when we are in bright sunlight the aperture of the pupil would be small to regulate the amount of light entering the eye preventing glare, discomfort and damage to eyes. As we enter a dark room less amount of light would enter our eyes due to small size of pupil,and we won't be able to see objects clearly. It takes some time to regulate the size of the pupil through iris. Hence,it requires some time to see things.
