The fault is not the universe.

There must be a defect in some people's eye balls Or maybe all humans.  A reason for vigilance or paranoia.  Pure speculation.  The eye is not the mind, therefore this 20/20 that glasses are all set on?  Is this correct to do exactly?  Must everyone have 20/20 vision?  And why stare so much in work and in free time?  Just questions that have psychological health concerns.
