Human eyes are made up of over 2 million working parts

Apart from your brain, your eyes are the most complex organs in the human body. With over 2 million complex moving parts that all work in sync with one another, the eyes need to work in an incredibly precise way. They take in over 36,000 pieces of information every hour, so those moving parts are all put to good use. When your eye takes in an image, the image is actually upside down, but the brain quickly corrects this with a flip.
