Wondering how the human eye works? Read this article to learn all about the complete makeup of the eye, including the cornea, retina, macula and pupil.
The iris controls the size of the pupil by expanding and contracting, and the pupil lets light through to the lens and interior portions of the eye. The sclera is the white part of the eye, which gives it shape and contains blood vessels that supply oxygen. The conjunctiva is a ...

In a number of ways, the human eye works much like a digital camera: Light is focused primarily by the cornea – the clear front surface of the eye, which acts like a camera lens. Theiris(colored part) of the eye functions like the diaphragm of a camera, controlling the amount of lig...
If an imbalance occurs between fluid production and outflow, thus increasing the amount of aqueous fluid, the pressure in the eye inevitably increases. This is one of the contributing factors that cause glaucoma. Cornea (shown here as light blue area to the left of the iris) The cornea is...
Iris The choroid continues at the front of the eyeball to form the iris. The iris is a flat, thin, ring-shaped structure sticking into the anterior chamber. This is the part that identifies a person’s eye colour. The iris contains both circular muscles going around the pupil and radial ...
