What is the function of the vitreous humor in the eye?

The vitreous humor is a clear gel-like substance that fills the space between the lens and the retina of the eye. Its primary function is to provide structure and shape to the eyeball. This gel maintains the spherical shape necessary for proper optical functioning and supports the retina by holding it in place against the choroid layer, which is important for visual stability.

The vitreous humor also acts as a cushion, protecting the retina from mechanical shocks and assisting in keeping the eye's internal environment stable. While it plays a role in light transmission, its key purpose is not to absorb or transport light, which is where other structures and fluids in the eye come into play.

The other functions mentioned, such as transporting nutrients and facilitating vision, are performed by other parts of the eye, such as the aqueous humor and the lens. Therefore, the focus on providing structure and shape highlights the essential role of the vitreous humor in maintaining the integrity and functionality of the eye.
