Question

A person walking in a dark corridor enters into a brightly lit room: 

 State the effect on the pupil of the eye. 

Solution

 A person can feel glare in the eyes when entering a brightly lit room from a dark corridor. This is because the pupil of the eyes are large when the person is walking in a dark corridor, and as the person enters a brightly lit room, a large amount of light enters the eyes; hence, he or she feels glare in the eyes. It takes some time for the pupil to get adjusted to the intensity of the surrounding light, and gradually, they contract.

  Is there an error in this question or solution?
