Eyes :::::::: Are the most complex organs you possess except for your brain.
Are composed of more than two million working parts.
Can process 36,000 bits of information every hour.
Under the right conditions, can discern the light of a candle at a distance of 14 miles.
Contribute towards 85% of your total knowledge.
Utilize 65% of all the pathways to the brain.
Can instantaneously set in motion hundreds of muscles and organs in your body.
In a normal life-span, will bring you almost 24 million images of the world around you.
The external muscles that move the eyes are the strongest muscles in the human body for the job that they have to do. They are 100 times more powerful than they need to be.
The adult eyeball measures about 1 inch (2.5 cm) in diameter. Of its total surface area only one-sixth is exposed -- the front portion.
The eye is the only part of the human body that can function at 100% ability at any moment, day or night, without rest. Your eyelids need rest, the external muscles of your eyes need rest, the lubrication of your eyes requires replenishment, but your eyes themselves "never" need rest. But please rest them!
