We have been doing eyes at school and we have discovered that every ones eyes are just about the same.  they have a pupil (which is actually a hole that opens wider when it is dark and shrinks when you go into bright light) an Iris (which is the coloured bit of your eye ) and a cornea (which is the gloppy clear stuff covering your eye). next we venture into the eye and what we see is a lens ( which is a hard thing that helps you to see things if your lens is too skinny or to fat you may have seeing proplems ) then we see the retina ( which is a clear liquid inside your eye which captures the images you see and processes them to the brain lickety split in less than a millisecond !)  at the back we have a little dent which is called the fovea ( which is where the images bounce off into the nerve which takes them to the brain.)
