what is an analogy for the retina
Retina Anatomy. A basic overview of retina anatomy will help you better understand why and how this eye disease affects oneâs vision. The best analogy for understanding how the eye works is to compare the eye to a camera. It is the back of the eyeball, the retina, that acts like film in a camera.The retina is a very thin layer of tissue lining the inside of the eye.he macula is a small spot, about the size of a pencil eraser, located in the center of the retina. This part of the retina is responsible for detailed, sharp, clear vision. A healthy macula is what gives a person 20/20 vision.
