Modern science introduces us to the very intriguing field of Genetics. This study enables us to understand what significance our physical appearances and family histories have. It can also help us to predict the illnesses and characteristics of living things from the future.
Let’s look into one of its most exciting applications which deal with the change in the color of our eyes, as a response to our emotions.
For a long time, people have struggled to find co-relations between the eye color and certain characteristics. For example people with green eyes were believed to be wicked.
However, your character has nothing to do with your eye color, whereas the eye color might experience a shift in spectrum depending upon your emotions.
Only the iris portion of your eyes is colored and when observed carefully, you may notice that the color does not remain consistent with throughout no matter how homogenous your eye appears from a distance.
The effect of your emotions is such that there is only a slight shift in spectrum of the eye color and not the entire tone changes. Three gene pairs contribute in determining the eye color instead of one.
The sympathetic nervous system is associated with our emotions. The pupil of our eyes dilates or constricts as a response to the external stimuli. So, external conditions or situations which lead us to be angry or stressed about something have a direct impact on the state of the pupil. It tends to dilate when we experience any such emotion.
Similar sentiments such as shock, sorrow, equanimity, etc also cause the pupil to either dilate or constrict.
Since the color of the eyes is not consistent throughout, by the virtue of this phenomenon wherein the pupil of our eyes changes its state as a response to change in our feelings in accordance with our sympathetic nervous system, the color of the eye changes by a slight spectrum shift.
When the pupil dilates, the colors take a shift towards right in the spectrum and when it constricts, it shifts towards left.
