What's the Retina?

Article Translations: (Spanish)

Retina

Say: RET-ih-nuh

The retina is at the back of your eye and it has light-sensitive cells called rods and cones. When you look at something, light hits the retina, then the rods and cones send electrical signals to the brain along the optic nerve. The brain uses these signals to interpret what you are seeing.
