Answer:
The eye has many parts that must work together to produce clear vision:
1.The sclera, or white part of the eye, protects the eyeball.
2.The pupil, or black dot at the centre of the eye, is an opening through which light can enter the eye.
3.The iris, or coloured part of the eye, surrounds the pupil. It controls how much light enters the eye by changing the size of the pupil.
4.The cornea, a clear window at the front of the eye, covers the iris and the pupil.
5.A clear lens, located behind the pupil, acts like a camera lens by focusing light onto the retina at the back of the eye.
6.The retina is a light-sensitive inner lining at the back of the eye. Ten different layers of cells work together in the retina to detect light and turn it into electrical impulses.
