The Bible does not speak of the eye being a window to the soul, yet it does represent the eye as being a lamp of the body. 

Matthew 6:22
''The eye is the lamp of the body; so then if your eye is clear, your whole body will be full of light.

Luke 11:34
''The eye is the lamp of your body; when your eye is clear, your whole body also is full of light; but when it is bad, your body also is full of darkness.
