Cornea | a clear, dome-shaped surface that covers the front of the eye |
Choroid | supplies blood to the retina |
Iris | colored part of eye. Protects the retina |
Function of Iris | Regulates the amount of light that enters the eye |
Retina | visual part of the eye |
Conjuctiva | keeps the eye from drying out |
Rods | night vision |
