Your eyes are most definitely the window to your soul. You've heard it a million times. People can really tell a lot about you from just looking into your eyes. That statement really seems to hold true when it comes to judging your willingness to tell the truth, your sincerity, and the depth of your heart if you follow the romantics.
There have even been scientific studies that show personalities are linked to the irises of a subject's eyes, and that your eye color may even indicate your pain tolerance.
That's all on a deep and personal level. But the skin around your eyes can tell a story all its own, too, indicating how much sleep you've received, how stressed you are, and whether you've done a good job protecting yourself from the sun. Your eyes really do reveal so much about you.
