Eye:
components of the eye:
-
-
Iris: the visible coloured ring at the front of the eye. It adjusts to control the amount of light that enters the eye through the pupil.
-
Aqueous and vitreous glands: watery, jelly-like fluids that fill the eye and keep it in shape and nourished.
-
Cornea: at the front of the eye and is transparent. light rays pass through the cornea to the retina.
Macula: has a very high concentration of photoreceptor cells - these detect light and sends signals to the brain, which interprets them as images.
Optic nerve: where the nerve cells exit the eye. There are no rods or cones there so it is called the 'blind spot'.
