Inverted

Summary: The image is inverted (upside down). However, your brain makes sense of it so that you see an image of the tree that is the right way up. The retina is a light-sensitive material. This means that it reacts quickly to light. This is because it contains Cells that respond to light. These cells are called photoreceptors. When light hits a photoreceptor, Chemical Reactions produce an electrical impulse. This electrical impulse travels up the optic nerve to your brain.
