Recently, we learnt the visual system in the sensation and perception chapter. One concept I found very interesting is the dilation of the pupil when we were learning the structures of the eye. We see sclera, iris, and pupil when we look someone in the eye. The sclera is the white of the eye, the iris is the color part of the eye, and the pupil is the circular hole. Light enters our eyes through pupils so that they will close or dilate as a reflex response to light and other things.
The dilation of the pupil can make one person more attractive due to psychological causes. You may find your girlfriend prettier when you are walking out of the movie theater because our eyes respond with papillary reflex from a darker place to a brighter place and pupils dilate. Moreover, in the Lilienfeld text, researches show that men and women tend to find the faces of each other with larger pupils more attractive. That explains why there is always a trend of large pupils. Models in magazine and ads are so appealing because photographers enlarge their pupils. Today, we can even make our pupil dilate by wearing cosmetic contact lenses or Circle contact lens. A Cosmetic contact lens is designed to change the appearance of the eye. We usually see actors wearing them in horror film and zombie movies. They enlarge pupils but in kind of scary ways. A Circle contact lens enlarges the pupil and the iris that makes eyes attractive but looks more natural.
