What is the role of the aqueous humor?

The role of the aqueous humor is primarily to provide nutrients and maintain intraocular pressure within the eye. This clear fluid is produced by the ciliary body and fills the anterior and posterior chambers of the eye, which are the spaces between the cornea and the lens. By providing nutrients to the avascular structures of the eye, such as the cornea and lens, the aqueous humor plays a crucial role in maintaining the health of these tissues.

Additionally, the aqueous humor is essential for maintaining a stable intraocular pressure, which is key to preserving the shape of the eye and ensuring that it functions properly. Proper intraocular pressure is necessary for the eye to maintain its structural integrity and to ensure that the optical components align properly for effective vision.

The other options listed have different functions; for example, while the cornea does play a role in refracting light, it does so independently of the aqueous humor. Color perception involves more complex biochemical pathways in the retina and is not directly related to the role of the aqueous humor. Strengthening the eye primarily involves structural components, such as the sclera and cornea, rather than the fluid within the chambers. Thus, the choice that encompasses the nutritional and pressure-maintaining functions of the aqueous humor is indeed the correct
