Why are your eyeballs filled with fluid?

[Moro]

To give the eyes their squishy shape, your eyeballs contain a lot of fluid. Without fluid, your eyeballs would collapse-almost like a beach ball without air. The fluid constantly circulates in and out of your eye and is filtered through a mesh-like covering, like a window screen. Behind your eyeball, there's a lot of fat; that's what pushes your eyes forward.

Aqueous humor is the clear, watery fluid that is continually produced inside the eye. It is different from your tears. Tears are produced by glands outside of the eye and moisten the outer surface of the eyeball.The aqueous humour is a transparent, gelatinous fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium, a structure supporting the lens.[1] It is located in the anterior and posterior chambers of the eye, the space between the lens and the cornea. It is not to be confused with vitreous humour, which is contained within the larger cavity of the eye behind the lens.

The fluid that is at the front of the eye, between the cornea and lens, is known as the aqueous humor. The function of the aqueous humor is to help the eye maintain it's internal pressure. Hope this helpful.
