The retina is the receiver of visual images at the back of the eye. Light passes through the frontal lens, then through the clear gel-like vitreous in the inner eyeball, to the retina at the back of the eye, which then sends electrical signals down the optic nerve to the brain.
Retina: The light-sensitive layers of nerve tissue at the back of the eye that receive images and sends them as electric signals through the optic nerve to the brain.

Retina : innermost of the three tunics of the eyeball, the retina is a ten layered nervous tissue membrane; it is continuous with the optic nerve and receives images of external objects and transmits visual impulses to the brain; its outer surface is in contact with the choroid and the inner surface with the vitreous body; the outermost layer is pigmented, whereas the inner nine layers are transparent.
The retina is a paper-thin tissue that lines the back of the eye and sends visual signals to the brain. In the middle of the retina is a tiny area called the macula. The macula is made up of millions of light-sensing cells that help to produce central vision. (Source: excerpt from Are You at Risk for Age-Related Macular Degeneration: NEI)
The retina is a light-sensitive tissue at the back of the eye. When light enters the eye, the retina changes the light into nerve signals. The retina then sends these signals along the optic nerve to the brain. Without a retina, the eye cannot communicate with the brain, making vision impossible.

Retina: The retina is a specialized structure of the eye. The retina is the innermost layer of the eyeball and lines most of the posterior region of the eye. The retina contains the visual receptors, the rods and the cones, which absorb light and transform it into electrical impulses that can be transmitted through the optic nerve of the nervous system.
Light flows through the cornea and the pupil onto the lens before it is projected onto the retina. Conditions that can afflict the retina include detached retina, diabetic retinopathy, trauma, and macular degeneration.
Retina: The retina is the lining at the back of the eye. The retina's job is to sense light coming into the eye. (Source: excerpt from Keep your eyes healthy: NIDDK)
