T1: Did you know your pupil changes in size? It is common for your pupil to adjust itself throughout the day.

T2: There is an important relationship between the environment and pupil size, your pupils increase or decrease in size depending on the amount of light around you.

T3: When there is less light around you, your pupils dilate(or enlarge) to let light into your eye. On the contrary, brightness constricts the pupils making them appear smaller, this allows less light to enter the eye.

T4: The muscle that controls your pupil size is the iris sphincter muscle, this muscle is located in the iris, the colored part of the eye.

T5: Certain emotions also dictate pupil size, usually pupils dilate when feeling attraction or fear. On the other hand, pupil constriction can be caused by overwhelming excitement.

T6: Next time you notice your pupil is a different size, remember that it is normal and part of its function.
