eyes are a very important part of the Face. Your eyes will tell people your real feelings. When a person smiles,check his or her eyes for smile lines and a warm expression. The lips can lie in a smile but the eyes cannot lie. when you look at the light,they get smaller and when you look at the dark they get bigger. your pupils also get bigger when you look at something you like and they get smaller when you look at something you do not like. So light-colored eyes are easier to read and dark eyes are a mystery.
