What are some interesting facts about eyes?

The human eye is an incredibly complex and intricate organ, capable of interpreting millions of visual stimuli per second. Some interesting facts about eyes include that they are the only part of the body that can see the outside world, that the pupils dilate when we are looking at someone we find attractive or when we are trying to solve a difficult problem, and that blue-eyed people share a single ancestor who lived between 6,000 and 10,000 years ago. Additionally, the eye contains over two million working parts and can process images that are upside down and reversed, thanks to the brain's ability to interpret the signals sent by the retina.
