What is at the back of the eye called?
The Back of the Eye. The vitreous cavity lies between the lens and the back of the eye. A jellylike substance called vitreous humor fills the cavity. Light that is focused into the eye by the cornea and lens passes through the vitreous onto the retina — the light-sensitive tissue lining the back of the eye.
What is behind the pupil of the eye?
Behind the anterior chamber is the eye’s iris (the colored part of the eye) and the dark hole in the middle called the pupil. Muscles in the iris dilate (widen) or constrict (narrow) the pupil to control the amount of light reaching the back of the eye. Directly behind the pupil sits the lens.
