Why is it difficult to find objects in dim light?
Why do you take time to find object when you enter in dim lighted room from outside in the sun?

When in sun, the iris of the eye is narrow and thus the pupil is constricted so that it allows less light to enter. As soon as we enter a dim light room directly after the sun, the iris still being narrow, allows little light to pass through it. However, within a few minutes the iris dilates the pupil allowing sufficient amount of light to pass through it. Thus we take some time to regain the original view.
