Cow's Eye

• The sclera is the thick, white part of the eye and is the outer layer of the eye.
• The cornea is the transparent front surface that covers most of the iris and pupil. This helps the eye focuses the light entering the eye
• The iris is the colored part of the eye that controls the size of the pupil. This is located between the cornea and the lens
• The pupil is the black circle in the center of the iris which allows light to enter the eye
• The lens is a transparent, lens that refracts light and focuses light rays on the retina. This is located behind the pupil.
• The retina is the light-sensitive layer at the back of the eye that detects images. This contains cones and cells and this connects to the brain by the optic nerve.
• The aqueous humor is the watery fluid that fills the anterior chamber of the eye. This keeps the cornea in a rounded shape.
• The vitreous humor is a thick, clear gel-like substance that fills the posterior cavity. This gives the eyeball its shape.
• The optic nerve is the nerve that carries information from the retina to the brain.
• The tapetum is the colorful and shiny part of the eye that enhances vision in low-light levels. This is found in animals with night vision. It is located behind the retina.
