What is the fluid found between the cornea and the lens?

• A. Retina
• B. Lens muscles
• C. Aqueous humor
• D. Iris

Answer: (C)

Aqueous humor. This clear fluid fills the anterior and posterior chambers of the eye, produced by the ciliary processes, and flows from the posterior chamber through the pupil into the anterior chamber. It nourishes the avascular structures like the cornea and lens, helps maintain intraocular pressure, and supports the eye’s optical properties. The retina lies at the back of the eye, the muscles controlling the lens are solid tissue (ciliary muscles), and the iris is a tissue structure between the cornea and lens—not a fluid.
