Explaining, light enters the eye.
Cornea - It is at the front of the eye. It is tough, transparent and convex.
Pupil - Dark hole in the middle of your eye.
Iris - The coloured part of your eye.
Lens - The lens is Bi-convex transparent disc.
Retina - Retina is layer of cells at the back of your eye that is sensitive to light.
Optic nerve - A bundle of nerve cells that connects the eye to the brain.
Light enters the eye through the see-through cornea. The Iris controls how much light entering the pupil. When it travels through the lens, the light is focused onto the retina lining in the back of the eye. The retina transforms the image into an optic impulse which travels along the optic nerve to the brain.
