retina
Rods and cones
The retina is the light-sensitive layer at the back of the eye.
It contains cells that detect light and color, converting visual information into nerve signals sent to the brain.
The ophthalmologist examined her retina for signs of damage.
Retinal scans use the eye's unique blood vessel patterns for identification.
