What is the retina?
the innermost light-sensitive membrane covering the back wall of
the eyeball; it is continuous with the optic nerve
6 layers of cells that line the back of the eyeball.
One layer is sensitive to light and is the first step in turning
light into vision.
These cells are a part of your brain.
The retina is the layer of cells in the back of the eyes
responsible for detecting light, which in turn allows you to see.
The specific cells responsible for detecting light are the
photoreceptors, more commonly referred to as rods and cones.
