. Cornea - the clear front window of the eye. The cornea transmits and focuses light into the eye |
. Optic Nerve - the nerve that connects the eye to the brain, which interprets them as images. |
| . Conjunctiva - part of the eye that produces the mucus layer of the tear film. |
. Pupil - the dark center in the middle of the iris. The pupil determines how much light is let into the eye. It changes size to accommodate for the amount of light that is available. |
| . Lacrimal Gland - gland that produces the middle watery layer of the tear film. |
. Retina - the nerve layer that lines the back of the eye. The retina senses light and creates impulses that are sent through the optic nerve to the brain. |
| . Macula - a small area in the retina that contains special light-sensitive cells. The macula allows you to see fine details clearly. |
. Tear Film - coating over the cornea that keeps the eye lubricated. The Tear Film consists of three layers, a mucus layer, a watery layer, and an oily-layer. |
. Meibomian Glands - glands in the eyelid that produce the oily layer of the tear film. |
. Vitreous - the clear, jelly-like substance that fills the middle part of the eye. |
