Our eyes work like a camera. Just like a camera lens focuses our cornea focuses light on the membrane called the retina. The cornea is transparent. It's found in the front of the eye and it helps focus light. Behind the pupil is a colorless, see threw structure called the crystalline lens. A clear fluid called the aqueous humor fills between the cornea and iris. The cornea focuses most of the light and then it goes through the lens. Behind the cornea is a colored, ring shaped membrane called the iris. The iris has an adjustable opening called the pupil which controls the amount of light to the eye.
Ciliary muscles surround the lens. The muscles keep the lens in place. When the muscles relax they pull and flatten the lens. Then the eye
