Why do we widen and narrow our eyes when we feel different emotions?
Eye widening vs. Eye narrowing
Eye widening - Fear and Surprise - The eye widening increases light
and sensitivity, expands our field of vision and we see more of what we like or what is
threatening.
Eye narrowing - Anger and Disgust - The eye narrowing squint
reduces light and sharpens our focus on the source of our displeasure.
