Eye (Earth-2356)

Eyes are the primary visual organ of many sentient and animal species. Most species possess a single pair of eyes located on their head, although some species, such as Abyssin, have only one eye, and others, like the Harch, possess several pairs. Yet other species, like the Melitto from Li-Toran, have no eyes at all, relying on other organs to navigate. The droid equivalent to an eye is a photoreceptor. Force techniques that used or require the use of the eyes are known as dojei.
