The optic system provides the view to the world and the incredible range of colours, shapes and objects. Light enters the eyes through the cornea (lens) which focuses and passes light through the pupil. This regulates the amount of light within the iris, the coloured part of the eye.
Muscles within the eye (ciliary muscles) cause the lens to bulge or flatten and transfer light to the retina. Within the retina, millions of light receptors called cones (for colour) and rods (for black and white) build an image which is then transferred to the brain for final evaluation, via the optic nerve.
