This anaolgy is brought to past for a few reasons.
1. If your looking into their eyes and your looking back.. You can tell if they like you
2. Lies.. If someone lies you can tell usually by looking them in the eyes
3. The term "eyes are the windows/gateways to the soul" has to do with how the eyes look and are shaped.. If you have ever tried to draw manga you learn that eyes change the persons atitude simply by changing there shapes
4. Some people belive that the eyes have memorey ingrams.. So looking into there eyes you can litterally see there life..
5. Check out a TV show called "lie to me" it might inlighten you
As to if I belive.. Yes..
