SCENE + HEARD: Daily Post Love Is in the Air, and it Seems, Love Is in the Eyes By Staff Friday, February 8, 2019 1:22 PM Valentine’s Day is right around the corner and who knew there was a scientific connection between love and your eyes. We have all heard the term “Love is in the Air,” but can love really be in the eyes? Actually, science has proven it so. Certain chemicals (or endorphins) that produce the emotion of love can be emitted through emotions expressed in the eyes. Romeo and Juliet and Antony and Cleopatra all can prove that love is in the eyes of the beholder. There are physiological changes in the eyes that occur when love is expressed between two individuals. Two people in love, love shown toward a family member, child, or pet all cause the same response: the pupil (black part in the center of the eye) dilates. The size of the pupil can be an indication of emotional responses and messages. According to Scientific American, the autonomic nervous system (our fight or flight response), causes the pupil to have a quick dilating response. This bounce in size is an automated response that gives scientists indication of mood or interest (or love) shown to a person or pet.
