The human eye is one of the largest machines on Earth

The human eye is one of the most powerful machines on the planet.It's like a 500 megapixel camera that can run in bright light,in near darkness,and even under water, though not real well.It communicates to our brains so much about the world.Our eyes are how we find partners,how we understand the people around us,how we read,and how we watch game shows on TV where people get knocked into cold water by padded wrecking balls.Yup, the human eye is pretty neat,and we're lucky enough to have two of them.
