We just learned about the Macula in the back of the eye.
Another part of the human eye is the Vitreous Body.
Inside the eye, most of it is filled up with a kind of clear gooey gel.
It's clear like water, but is thicker almost like jelly.
This is called the vitreous body, or sometimes the vitreous humor.
It helps the eye keep its shape, and it helps keep the vision clear between the lens and the retina.
