retinas
Inner eye screens
Retinas is the plural of retina, the light-sensitive layer of tissue at the back of the eye that receives images and transmits them to the brain via the optic nerve.
The word appears in medical contexts The doctor examined both retinas for signs of damage and in technology referring to high-resolution displays retina screens.
