Etymology
From Latin vitreus (made of glass), from vitrum (glass)

The vitreous humor, or vitreous, is the glassy clear sticky material within the eye. Its actual function is still unknown. When the vitreous gel separates from the retina, one can get "floaters and flashes". During some types of retinal surgery, the vitreous is removed (a vitrectomy) and replaced with saline solution, with seemingly no ill effect in most cases. "Vitreous" also means "glassy" in a non-medical sense, from which we get vitrine, vitriol, vitriolic, and vitrescent.
