Falling in love is one of the most beautiful feelings. Isn't it? According to a study,the eyes of the individual in love depict it all when he/she in love. The romantic depiction of the eyes as 'windows to the soul' is not just another poetic expression to inspire the ones in love; it is true, indeed. When you see the person you are in love with, your pupil dilate.
Our pupils naturally dilate throughout the day. The main reason for this is to control the amount of light that enters the lens; allowing us to focus on objects. The muscles in the iris (the colored part of the eye) control pupil size. Pupils get bigger and smaller depending on the amount of light around them.
Autonomous nervous system is responsible for the dilation and constriction of the pupils; the same system is responsible for goose bumps as well as heart rates. When you look at the sun, you are unable to bear its rays and hence you are never able to stare at it. However, that's not the only thing that your eyes react to, when we experience a physiological response to emotions such as fear or in this case attraction,it causes our pupils to dilate.
Dopamine,the happy hormone is a powerful neurotransmitters which is regulated within the nervous system and associated with feelings of pleasure. The chemical release of dopamine actually causes the pupils to dilate.
Dopamine levels peak when you are expecting something good. We're talking about when you are about tp eat your favorite slice of cake; when spend time with someone you love or, in some cases, during an addiction.
With the matters of the heart, the old belief that pupils enlarge when we look at someone we are physically attracted to, can indeed be backed up-which could be where the phrase - 'easy on the eye' derives from.
