shows dilated pupils or "bedroom eyes."
The human pupil will dilate when a person is aroused or excited. The resulting "darkening" of the eye has been shown by scientists to be more attractive to people. "Bedroom eyes" are eyes in which the pupil has grown to cover a larger portion of the iris. Mood lighting or candlelight can help to accelerate the biologic response of a growing pupil. And just as an aside, dilate is the process of widening or expanding. I've read many descriptions where dilate implies either a shrinking or an enlarging of the pupil. Shrinking of the pupils is the pupil constricting, not dilating. And in romance writing, constricting is bad...in more ways than one.
Why does this happen? Well, in an article in The Scientist entitled The Meaning of Pupil Dilation, the author explains:
"For more than a century, scientists have known that our pupils respond to more than changes in light. They also betray mental and emotional commotion within. In fact, pupil dilation correlates with arousal so consistently that researchers use pupil size, or pupillometry, to investigate a wide range of psychological phenomena. And they do this without knowing exactly why our eyes behave this way. “Nobody really knows for sure what these changes do,” said Stuart Steinhauer, who directs the Biometrics Research Lab at the University of Pittsburgh School of Medicine.
While the visual cortex in the back of the brain assembles the images we see, a different, older part of our nervous system manages the continuous tuning of our pupil size, alongside other functions—like heart rate and perspiration—that operate mostly outside our conscious control. This autonomic nervous system dictates the movement of the iris, like the lens of a camera, to regulate the amount of light that enters the pupil."

The point is that eyes will not necessarily change color, but they will lighten or darken according to the situation. Alcohol will cause the pupils to constrict...something that happens to another body part when it gets wet. Pain will cause the pupils to dilate. I came across this description in the PSYBlog:
"Chapman et al. (1999) fired small electric shocks into people's fingertips and measured how much their pupils dilated. At maximum intensity the pupils dilated by about 0.2mm.
But that was only to a relatively tame current. Imagine what you could do to my pupils if you plugged me into the mains."
This is great news for me because my details about the abilities of the jinn often include small and large electric shocks being fired at someone.The science of the eyes is a fascinating topic. In fiction, such information is invaluable. When you're writing in the perspective of one character but you need to let your reader know what the other character is thinking, describe their eyes. Someone may very well be thinking romantic thoughts if that pupil keeps getting bigger and bigger and bigger.
