Think of your pupils (the black spot in the middle of your eyeballs) as a window shade. When you are in normal light they shrink to let in only as much light as needed so your cornea doesn't get damaged. when you are in the dark your pupil opens fully. It takes about a minute either way for your eyes to adjust.

When you enter a cinema hall you cannot see properly for a short time This is because?
When we enter the cinema hall we are unable to see what is present inside as soon as we enter the cinema hall, but gradually our vision develops . And why is it so? It is because we have two types of cells in our eye, rods and cones. These rods contain pigment called rhodopsin (the visual purple) and the cones contain pigment called iodopsin (visual violet). Rods respond to light of low intensity and they help us to see in darkness but in the bright light the rhodopsin pigment in the rods degenerate so that we get adopted to the day(more light). But when we suddenly enter the cinema hall, which is dark, it takes time for the regeneration of the rhodopsin pigment and the pupils dilate allowing more light to enter. And this is the reason why we are unable to see clearly as soon as we enter the cinema hall.
