"The mechanism that makes the eye Your eyes are at work from the moment you wake up, to the time you close them and go to sleep. They assimilate information about the world around you. Eyes perceive shapes, sense colors and distinguish movements. Little do we realise that all these functions that our eyes perform, are stitched together by a complex mechanism that works in coordination with our brain to complete the process of visual perception and processing. Let us briefly look at the various components that make up our eyes: 1. The white part of the eyeball is called the sclera. The sclera is made up of a tough material and covers most of the eyeball. It also has visible red blood vessels that deliver blood to it. 2. The cornea is a transparent protruding dome in front of the coloured part of the eye. The cornea helps the eye focus as light makes its way through. 3. Immediately behind the cornea is the anterior chamber, a space filled with a transparent fluid that nourishes the eye and keeps it healthy. 4. After the anterior chamber is the iris that lends the eye its natural colour. The iris has muscles attached to it that changes its shape, and thus regulates the entry of light. 5. The pupil is the black circlular opening in the center of the iris, that allows and controls the amount of light that enters. The pupils become small when the light is bright and opens wider when the light is less. 6. After the light enters the pupil, it hits the lens. The lens is behind the iris and is clear and colourless. The lens' job is to focus the light rays to the back of the eyeball. "
