Explanation: 

Detailed explanation-1: -The vitreous humor is a transparent, colorless, gel-like substance located in the posterior chamber of the eye. It helps maintain the round shape of the eye and can also help with vision clarity and shock absorbance. With aging, the vitreous humor undergoes vitreous degeneration, acquiring a thinner liquid consistency.

Detailed explanation-2: -Produced by cells in the non-pigmented portion of the ciliary body, the vitreous humour is derived from embryonic mesenchyme cells, which degenerate after birth. The nature and composition of the vitreous humour changes over the course of life.

Detailed explanation-3: -The vitreous is the gel-like fluid that fills your eye. It’s full of tiny fibers that attach to your retina (the light-sensitive layer of tissue at the back of the eye). As you get older, the fibers of your vitreous pull away from the retina. This is called vitreous detachment.
