Right vitreous body

Looks like

A clear jelly filling the large space behind the lens, about two thirds of the eye's volume.

What it does

Keeps the eyeball's shape and lets light pass to the retina.

Keeping it well

It liquefies and pulls away with age, causing floaters. A shower of new floaters, flashes or a curtain over vision needs same-day care.
