Do you know that:

* … almost half of our brain is dealing with processing vision? Humans are to a very high extent visually-sensing creatures.

* … under the right conditions the eye can differentiate  the light of a candle positioned at a distance of 23 kilometers?

* … the eye can suddenly cause the motion of hundreds of muscles and organs in your body?

* … at its normal lifespan your eye will process nearly 24 million images of the world around you?

* … the external muscles that move the eye are the strongest in the human body compared to their assigned duty. They are 100 times stronger than is needed.

* … the human eye is the only part of our body that could function at 100% at any given time, day or night, without a break.
