Retina Coloring Page

Our eyes are at work when reading text in books, writing calculations in your notebook, or even when throwing or kicking a ball. What does the inside of the eye look like? At the back of the eye, there is a tissue called the retina, which is lined with many types of cells that receive the light entering the eye and convert them into signals sent to the brain.
