This is the eye. The eye provides us with vision so we can see and process visual detail. I will be explaining how it works in this Storyboard.
This is the Cornea. Light enters the eye through here. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye.
This is the pupil. The pupil controls the amount of light entering the eye. It is surrounded by the iris, the coloured part of the eye.
The light travels through it bends creating an upside down image on the retina. The brain eventually turns the image the right way up. The retina turns light into signals about images that the brain can understand. It is full of Rods (night) and Cones (daylight)
Once the image is clearly focused on the retina, energy in the light that makes up that image creates an electrical signal. Nerve impulses can then carry information about that image to the brain through the optic nerve.
The optic nerve then sends signals to the brain which create an image which is what we see.
