An old saying goes, "The eyes are the windows to the soul." This means that your eyes can show what you are thinking or feeling. However, according to some cultures, your eyes can also tell you what you will be in the future, and this is commonly called "Sanpaku Eyes." "Three whites" is what the Japanese words "Sanpaku" and "Sanpaku gan" mean. This phrase refers to people whose eyes are white at the top or bottom of the iris, even when they are looking straight ahead.
