Is the lens in the posterior chamber?
Posterior chamber: The posterior chamber is between the iris and lens. The lens is behind the iris and is normally clear. Light passes through the pupil to the lens. The lens is held in place by small tissue strands or fibres (zonules) extending from the inner wall of the eye.

How does light travel through the eye?
Light enters the cornea, the clear “window” of the eye. The cornea bends the light so it passes through the pupil. The iris makes the pupil bigger or smaller, which determines how much light gets to the lens. The lens angles the light through the clear vitreous to focus it on the retina.
What is the first layer of your eye called?
The clear front of your eye is called the cornea. This transparent disc sits over the pupil and iris, protecting them and letting in light. It is highly sensitive. The cornea also forms the first part of the process of focusing what you look at into an image on the back of your eye (see below).
What liquid is in the eye?
Fluid fills most of the inside of the eye. The chambers in front of the lens (both the anterior and posterior chambers) are filled with a clear, watery fluid called aqueous humour. The large space behind the lens (the vitreous chamber) contains a thick, gel-like fluid called vitreous humour or vitreous gel.
