Your pupils don't actually change size. When you or another person lies your eyes will naturally glance left. Because the left side of a person's brain has to do with creativity. The person lieing has no control over this it is sycological

∙ 14y agoYour pupils, small openings in the cornea of your eye (to allow light to pass through to the retina, which sends images to your brain) will increase and decrease in size depending on the amount of light you're in. The darker it is, the bigger your pupils will get in most cases. Some other factors can change your pupils' size, like fear/stress, but changes in light affect everyone's pupils.
