### part of speech

noun (a retina, retinas)

### meaning for a pupil

The retina is the thin layer at the back of the inside of the eye that senses light and sends messages to the brain. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/R/retina/#m1)

### sense in the lessons

In science, light enters through the pupil, the lens focuses it on the retina, and the optic nerve takes the signal to the brain. The image on the retina is upside down; the brain turns it round. Rods see in dim light; cones see colour.

### examples
