The tissues of the eye are prone to dry out very quickly, and require fluidity to function. For example, the aqueous humor in the eye maintains the right pressure inside the eye and transports nutrients. That's why the eye has ducts that constantly secrete fluids into it.

The liquid inside the eye is called the vitreous. Vitreous is a clear, gelatinous, and avascular substance, filling the space bound by the lens, retina, and optic disc. A layer of cells, termed the internal limiting membrane, coats the inner surface of the retina, separating it from the vitreous. The liquid help provide the shape and form for the eye.
Vitreous body comprises four fifths of the globe, averaging 4 mL in an adult. Vitreous is 99% water, with collagen and hyaluronic acid comprising the remaining 1%.

The aqueous humor, anterior to (in front of) the lens, and the vitreous humor, described above are vital to the proper refraction of the light that strikes the retina, causing chemical reaction in the rods and cones, allowing you to "see".
