Take this interactive tour of the eye to discover how it works. Begin by hovering over each part of the eye to learn its name and function. Next, investigate how changing the level of brightness affects the size of the pupil, and how the cornea bends the light rays as they enter the eye. Follow that by playing with a focus tool to see the lens adjust its shape, and the inverted image appear at the back of the eye. Finally, see how the image is transmitted as light impulses to the optic nerve and then to the brain, which converts them back into an image.
