"Your eyes are a window to your soul."
That phrase is more than just a cliché. Research has proven that your eyes really do give away a lot about what's going on inside your mind.
Research has also shown that, through iridology, your entire physical state can be observed with great accuracy.
It should come as no surprise, then, that your eyes also reveal a lot about your personality. Scientists at the Orebro University in Sweden supported this in a study involving 428 subjects.
It all has to do with genetics. The same genes that affect eye shape and size affect personality traits like confidence and outlook.
