Retina: Light receiver inside and at the back of the eye
Retina: The retina is the lining at the back of the eye. The retina's job is to sense light coming into the eye. 1
Introduction: 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.
Introduction: 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.2

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.3
