Eye Anatomy Introduction

Even though the eye is small, only about 1 inch in diameter, it serves a very important function - your sense of sight. Vision is arguably the most used of the 5 senses and is one of the primary means that we use to gather information from our surroundings.
 
The eye is often compared to a camera. Each gathers light and then transforms that light into a “picture.” Both also have lenses to focus the incoming light. A camera uses the film to create a picture, whereas the eye uses a specialized layer of cells, called the retina, to produce an image.
