What is the vitreous humor?

The vitreous humor is a clear, gel-like material that occupies the space between the lens and the retina in the back of the eye. Its main function is to help maintain the round shape of the eyeball, providing structural support. This jelly-like substance also plays a role in the optical properties of the eye, allowing light to pass through and reach the retina without distortion. The consistency and volume of the vitreous humor are essential for maintaining the integrity and proper functioning of the eye.

Other options describe different components or substances of the eye. The front of the eye is filled with the aqueous humor, which is a watery fluid that provides nourishment and maintains intraocular pressure. The colored part of the eye refers to the iris, which controls the amount of light entering through the pupil. Understanding the unique roles and characteristics of these components is vital for comprehending overall eye anatomy and function.
