An unseen world part 1 

The human eye is a wonderful organ.

Our eyes tell us more about the world around us than any of our other sense organ do. 

The size and shape of things their color their distance from us and whether one object is 

in front or in back above or our eyes. We can see things which are all 

things we learn by using

our eyes. We can see things

that are only a few inches  in

front of our eyes and we can look out 

the window and instantly see things

more than a mile away.
