The white of the eye nourishes the cornea and so has many blood vessels.  It produces tears and another fluid which helps keep the eyes moist by flushing salt water over them.  This is done when we blink, which we do about 30,000 times a day.  Blinking also helps remove foreign particles that might damage this sensitive organ.

Everything about the eye is automatic—we can see stars trillions of miles away, and yet with no thought we can focus on a tiny object just a few inches away.

When watching an exciting activity, the eye will send millions of electrical impulses instantly to the brain, which immediately takes over to put the information to use.  The picture received by the eye is always upside down, but the brain turns it right side up.

The eye is actually one of the great masterpieces of the Lord God, the divine Creator.  Our eyes are not just for this life, but we will see in eternity as well.  Job said, “ ... my Redeemer liveth ... .  Whom I shall see for myself, and mine eyes shall behold ... ” (Job 19:25, 27).  The Lord said, “Father, I will that they also, Whom Thou hast given Me ... may (see) My glory ... ” (John 17:24).
