Eye Structure (and function)

Conjunctiva function...

• protects cornea

• where eye muscles attach

• where refraction (bending) of light happens

• keeps the shape of the eye

Aqueous humor function...

• protects cornea

• where eye muscles attach

• where refraction (bending) of light happens

• keeps the shape of the eye

sclera function...

• protects cornea

• where eye muscles attach

• where refraction (bending) of light happens

• keeps the shape of the eye

cornea function...

• protects cornea

• where eye muscles attach

• where refraction (bending) of light happens

iris function...

• adjusts the size of the pupil

• where light enters the eye

• changes shape of lens

ciliary body function...

• adjusts the size of the pupil

• where light enters the eye

• changes shape of lens

pupil function...

• adjusts the size of the pupil

• where light enters the eye

• changes shape of lens

lens function....

• rich in cone cells, gives clear daylight colour vision

• refracts light and focuses light rays onto retina

• contains rod and cone cells

• sends impulses from retina to brain

retina function....
