Our pupils dilate when we are seeing something stimulating or we are in low light. If we are aroused our pupils dilate in order to take in more of our pleasing surroundings. Often during courtship pupils stay dilated. You can tell when someone is aroused by looking closely at their pupils in constant surrounding light.
The pupils look like round, black dots in the center of the eyes, but they are actually openings that allow light to enter the eyes. The size of the opening is controlled by the iris, the colored portion of the eye surrounding the pupil. The pupils constantly change size in response to light, to the eyeâs focusing distance, and to emotions. Normally, the pupils dilate (enlarge) in darker conditions to allow more light to enter the eye. The medical term for dilated pupils is mydriasis. Medications or other drugs can also cause the pupil to dilate, either intentionally or as a side effect. For example, eye care professionals often use eye drops that dilate the pupils in order to examine structures at the back of eye, such as the retina.
