Answer :

We cannot see our seats first when we enter a darkened cinema hall from bright light but gradually they become visible. This is due to the reason because in bright sunshine the pupil of our eye is small and when we just enter the darkened room very little light enters our eye due to which we cannot see properly. After a while, when the pupil of our eye expands, more light enters our eye and we can see clearly.
