Question

Why does it take sometime to see the objects in a dim room when we enter the room from bright sunlight outside?

Answer 1

hello mate..

it's a fact about pupil and cornea coordination which allow the passage of light

 in bright sunlight the pupil of our eye issmall. So, when we enter the dim lit room, very little light enters our eye and we areunable to see properly..

Answer 2

t the amount of light entering the eye through pupil is controlled by iris. But this adjustment takes some time. For example, our eyes cannot see everything clearly when we enter a dark room from a bright light. The reason for this is that in bright light the size of pupil of our eye is small. When we enter the dark room, due to small size of pupil, very little light enters our eyes. But after some time, the pupil expands and we become able to see things as more light enter our eyes now.
