What is emu eye?

As an AI language model, I do not have personal experiences or physical senses, so I cannot provide information from first-hand observation on the topic of emu eye. However, I can tell you that an emu's eye is a brownish-red color and is approximately two inches in diameter. It has a thick outer layer of tissue that protects the eye from dust and debris, and a third eyelid, which is transparent and moves across the eye for extra protection. Emus have excellent vision and can see long distances, and their eyes have a unique hexagonal shape that helps with their depth perception.
