Why is it that when there is sudden darkness the sight is not clear?
your eyes are trying to adjust to the amount of light . when there is lots of light, your pupils get smaller and when there is not enough light, your pupils get larger. therefore, when a bright light turns off and leaves you in sudden darkness., your pupils are widening to adjust to the amount of light it needs to let in. TRY IT YOUSELF: -make the room dark -stand in front of a mirror with a flashlight -shine the light in your eye and watch your pupil close up -then shine the light into the mirror (away from your eye but still so you can see it) and -watch your pupil get larger

Do you have to think about it when you want the size of your pupil to change?
No; the change in the size of your pupil is an involuntary action, meaning that it happens without you thinking about it. The size of your pupils adjust to stimuli, such as bright light. If a bright light was shined in your eyes, your pupils would get smaller in order to let as little light in as possible. Reversely, if you're in a dark room, your pupils will get bigger to let in as much light as possible.
Why can't you see after the lights go out?
It takes a few seconds for your pupils to adjust. In the dark your pupils open very wide to catch all the available light and they contract in high light levels (like sunlight) This adjustment takes up to a few seconds.
