Solution

When we are in the bright sun, the pupil of the eye contracts and lets in minimum light. However, when we enter a darkened cinema hall, the pupil does not immediately dilate and we are unable to see in the low-light conditions. But, after some time, the pupil opens to allow more light into the eye and we are able to see clearly.
