Human eyes have over two million working parts.

Per the Canadian Association of Optometrists, your eyes have two million working (or moving) parts. On top of that, they also have seven million cones, which are what allow you to see both color and detail. As for your ability to see in the dark, that's made possible with the help of a whopping 100 million cells, or rods.
