Function of the Human Eye

What is the function of the aqueous humour?

• Choroid; this is a thin layer of black tissue just beneath the retina that prevents light from being reflected back out of the eyes.

• Blind Spot; the point at which the retina and the optic nerve meet there are no light sensitive cells present therefore there is no vision.

• Cornea; the clear part of the sclera and lets light into the eye.

• Aqueous Humour; this is a thick watery substance that fills the front of the eye and provides nutrients for the lens.

• Conjunctiva; a thin membrane that covers the cornea.

What is the function of the iris?

• Iris; the colored part of the eye that controls the size of the pupil and thus the amount of light entering the eye.

• Conjunctiva; a thin membrane that covers the cornea.
