Among the blind, the squinter rules.

Blind is the bookless man.

A nod is as good as a wink to a blind man.

There are none so blind as those, that will not see.

Men in the game are blind to what men looking on see clearly.

In the kingdom of the blind men, those who are blessed with one eye are kings.

If the eye does not want to see, neither light nor glasses will help.
