Ratina-the light sensitive screen of of the human being on which the image is formed it contain two types of photosynthesis cells called the rods and cones.
cornea - the clear protective outer layer of the eye.
ciliary muscle - the flexible muscle which enable the islands to change its shape for seeing object at different distances.
pupil- the opening in the centre of the Aries it appear black as no light is reflected from it.

hey mate
here is your answer
Retina the image of the object in front of the eye is formed on the retina which acts like a screen .retina contains several Nerve cells it consists of cones and rods and cones are sensitive to bright light while rods are sensitive to dim light .the sensation of the image of the retina is carried to the Brain by the optic nerves.
cornea the part of the sclera in front of the bulging part of the eye is transparent and is called the cornea. it protects the eye.
Cillary muscles a ring of smooth muscle fibres that is responsible for changing the shape of the lense of the eye to achieve accommodation. suspensory ligaments contain muscle to the lens.
Pupil the hole in the centre of the iris In The Pupil. the amount of light entering the eye is controlled by the muscles of the iris. which contract all dilate the pupils. The Pupil becomes larger in less light to allow more light to go in and in bright light it constricts or becomes smaller to restrict the amount of light going in.
