Human Eyes: The eye muscles are the most active muscles in the whole body. Eyes are composed of more than two million working parts. The eye can process 36,000 bits of information every hour. Eyes can instantaneously set in motion hundreds of muscles and organs in your body. 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 be. The eye is the only part of the human body that can function at 100% ability at any moment, day or night
The cornea is approximately the size and thickness of a dime. A blink of an eye lasts about one tenth of a second. The average person blinks their eyes about 11,500 times per day or about 4.2 million times per year. There are only two tissues in your body that do not receive oxygen from your blood corneas and nails.

Animal Eyes!

An owl can see a mouse moving over 150 feet away with light no brighter than a candle! A cat's eyes glow in the dark because of special silvery "mirrors" that reflect light, making it much easier for them to see in the dark.
So-called "color-blindness," in which colors such as green and red are hard to distinguish, affects about 1 in 30 people and many times more men than women!
