Eyes are organs that detect light and help us to see. They do so by converting the light into electro-chemical impulses into neurons. So light basically bounces of the object we wish to see and sends the image back to our brain. Even though our eyes look pretty simple.. there are a lot of components that go together to make them up and they're all very intricate and complicated. Perhaps one of the most interesting facts, the human eye can distinguish around 10 million different colours.
