Nothing in the visual field allows you to infer that it is seen by an eye.

We can see nothing face to face; our utmost seeing is but a fumbling of blind finger-ends in an overcrowded pocket.

Perhaps there had never been anything at all to see.

Faith is the eye that sees nothing and rejoices in it.

The window has a wonderful view of a lake, but the view doesn't view itself. It exists in this world colorless, shapeless, soundless, odorless, and painless.

It is a terrible thing to see and have no vision.

Darkness is only in the mortal eye, that thinks it sees, but sees not.

Eyes that are blind have no way to tell the loveliness of faces and features; eyes with no pupils have no way to tell the beauty of colored and embroidered silks.

Nonononono…! You don't see anything…

Don't worry. I am like most people. I can keep my eyes and still see nothing.

They do not see what they look at, hence they know not what they do.

Where there is no vision, there is no hope.

Thou hast seen nothing yet.

Blind eyes cannot read.
