Question 1

Why do your pupils dilate when you see someone you love?

Accepted Answer

Attraction activates the sympathetic nervous system, which releases norepinephrine and pulls the pupil open. This automatic response can widen the pupil by up to forty-five percent and cannot be consciously controlled or faked.

Question 2

Does pupil dilation always mean attraction?

Accepted Answer

No. Pupils dilate with any strong arousal, including fear, surprise, pain, and mental effort. The pupil signals intensity, not a specific emotion, so context determines whether wide eyes mean desire or danger.

Question 3

What is pupillometry?

Accepted Answer

Pupillometry is the measurement of pupil size as an index of emotional and mental states. Psychologist Eckhard Hess coined the term in 1960 after finding that pupils widen in response to images a person finds interesting or attractive.
