Parts of the Eye
Some of the most important parts of the eye include:
Pupil- the dark, circular opening in the center of the iris, varying in size to regulate the amount of light reaching the retina
Lens- a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina
Iris- a flat, coloured, ring-shaped membrane behind the cornea
Cornea- transparent layer forming the front of the eye that helps refract light
onto the retina
Sclera- the white outer layer of the eyeball
Optic nerve- transmits impulses to the brain from the retina
Retina- a layer at the back of the eyeball containing cells that are sensitive to
light and that trigger nerve impulses that pass via the optic nerve
Choroid- the pigmented vascular layer of the eyeball between the retina and
the sclera
