The lens divides the eyeball into which two cavities?

The lens of the eye is a transparent structure that plays a critical role in focusing light onto the retina. It divides the interior of the eyeball into two primary cavities: the anterior cavity and the posterior cavity.

The anterior cavity is located in front of the lens and is filled with a clear fluid known as aqueous humor, which helps maintain intraocular pressure and provides nutrients to the avascular structures of the eye. This cavity further divides into the anterior chamber, situated between the cornea and the iris, and the posterior chamber, located between the iris and the lens.

The posterior cavity, on the other hand, is much larger and contains the vitreous humor, a gel-like substance that helps maintain the shape of the eyeball and provides support to the retina. This cavity extends from the back of the lens to the retina at the back of the eye.

This anatomical division is essential for understanding the eye's overall structure and the functions of different segments, particularly in relation to how they interact with light and visual processing. The other choices do not accurately describe the functional anatomical divisions of the eye created by the lens.
