Ex. 7. Read the following text:

EYE

The eyes are unique instruments, able to receive definite information about the world outside our body. Thousands of times a day, the eyes move and focus on images near and far. The structure of the eye is very complex. The eye consists of conjunctiva, sclera, cornea, lens, retina, iris, pupil, anterior chamber (aqueous humor), canal of Schlemn, posterior chamber (vitreous humor), fovea (focal point), choroids, and optic nerve.

The conjunctiva runs along the inside of the eyelid and the outermost portion of the eye. It meets the sclera, the tough white layer that covers most of the eyeball. Both contain tiny blood vessels that nourish the eye.

Inside the conjunctiva at the center of the eye the cornea lies. This layer of clear tissue with its film of tears provides about two-thirds of the focusing power of the eye. The cornea refracts light as it enters the eye.

The pupil and iris lie behind the cornea. The pupil is the opening through which light passes to the back of the eye. Muscles controlling the iris (the colored part of the eye) allow it to change the size of the pupil to adjust to the amount of light. The pupil becomes larger in dim light and smaller in bright light to protect the delicate retina from excessive light.

Between the cornea and the iris the anterior chamber lies. This space is filled with aqueous humor. This fluid is manufactured in the posterior chamber of the eye. The fluid passes into the anterior chamber through the pupil and then is absorbed into the bloodstream through the canal of Schlemm in the angle where the iris meets the cornea.

Eye

Behind the iris and anterior chamber the lens is. This colorless tissue is enclosed in a capsule and suspended in the middle of the eye by a net of fibers. The lens can change shape in order to focus light rays on the retina.

The bulk of the eyeball, which is behind the lens, is formed by the round posterior chamber. It is filled with a colorless, gelatin-like substance known as the vitreous humor.

Retina is located behind the vitreous chamber. The retina of the eye is equivalent to the film of the camera. Composed of 10 layers, the retina processes the light images projected from the cornea and lens.

The retina is nourished primarily by the choroids. This multilayered tissue, which lies between the retina and the sclera, is composed of veins and arteries.

Fovea located in the center of the retina provides the most acute vision. This section is the most visually sensitive part of the eye.

The optic nerve takes the electrical impulses recorded by the retina and transmits them to the brain. The optic nerve interprets these messages into what we perceive as sight.
