Eye Anatomy – The Retina

Cross Section of the Eye

The retina is the delicate lining at the back of the eye that functions much like the film in a camera. It receives light through the lens in your eye, forms that light into images, and sends those images to the brain, enabling you to see.

The retina is composed of several layers of cells, including nerve cells, that do many things. Unlike the lens in the front of your eye, which can be replaced if it becomes cloudy (cataracts), these cells cannot be replaced by current medical technology.

Q: Description of the vitreous.

A: The vitreous is the clear, gel-like mass that fills the space between the lens and the retina.
