Best Answer

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.

The retina, a 5 square centimeter area in the back of the eye, is where all light detection takes place. The retina is a network of nerves connected to over 100 million photosensitive rods and cones. The signals created by these rods and cones are then sent via the optic nerve to the brain.

The top layer of the retina surprisingly does not interpret the light that strikes it. This layer, called the Plexiform layer, is a web of optical nerves. These nerves carry the signals of rods and cones to the optic nerve. This web is located between the photosensitive cells and the vitreous humor so that the web's cells can be nourished. Fortunately, these cells are nearly transparent so only minimally interfere with light striking the photosensitive cells.

The bottom layer of the retina is called the choroid. The choroid serves a double purpose: nourishment and absorption. The choroid carries blood to the retina and the humors, providing nourishment to the eye. In addition, the choroid absorbs any light that strikes it. This is extremely important, because light that passes through the rods and cones does not reflect back. If the light did reflect, the photo-sensitive cells would receive the light message twice, and would think that there was twice as much light as there really was.

Human retina contains two type of cells known as rod cells and cone cells ,which helps in night and bright vision respectively.

The retina also has photoreceptors for color.

The retina is comprised mainly of tissue supplied with many small blood vessels.
