Do your puples get larger

Answer 1

Your pupils enlarge in dark light so more light comes in. They constrict in bright light to reduce the amount of light. They are affected by drugs. Many abused/illegal drugs causes the pupils to constrict. This is a neat exercise. Rub the short hairs on the back of your neck below your hairline. Your pupils will constrict and enlarge. It is not known why this occurs. There is a theory that when people lie, their pupils dilate.
