As I am still not over with my yesterday's ruffling, I am extending my "eye" topic to Thursday 13.
Here are 13 cool eye facts for you!
Our EYES ---
- ...are the most complex organs you possess except for your brain.
- ...are composed of more than two million working parts.
- ...cornea is the only living tissue in the human body that does not contain any blood vessels.
- ...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 our total knowledge.
- ...utilize 65% of all the pathways to the brain.
- ...can instantaneously set in motion hundreds of muscles and organs in the body.
- ...in a normal life-span, will bring us almost 24 million images of the world around us.
- ...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.
- ...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!
- ...eyes are your most precious sense... care for them properly!
Happy Thursday everyone!
TWO MILLION working parts? Oh my...
