The human eye forms the image of an object at its retina. The retina acts as a screen for forming the image. The retina is the layer of nerve cells lining the back wall inside the eye. This layer senses light and sends signals to the brain so you can see.
It is a light-sensitive layer that comprises numerous nerve cells. It transforms images formed by the lens into electrical impulses. These electrical impulses are then transmitted to the brain through optic nerves.
