Level#1

Most eye problems occur when the lens does not focus the "picture" exactly on the retina. A nearsighted person can see close objects clearly. Objects that are far away look fuzzy and blurred. Because the eyeballs are too long, a picture is focused in front of the retina, instead of on the retina. To a farsighted person, close objects look fuzzy, and faraway objects look clear and crisp. The eyeballs of the farsighted person are too short. A picture is focused behind the retina, instead of on the retina.

1. When do most eye problems occur?







2. What can a nearsighted person see clearly?







3. What do objects that are far away look like to a nearsighted person?









Level#2

Most eye problems occur when the lens does not focus the "picture" exactly on the retina. A nearsighted person can see close objects clearly. Objects that are far away look fuzzy and blurred. Because the eyeballs are too long, a picture is focused in front of the retina, instead of on the retina. To a farsighted person, close objects look fuzzy, and faraway objects look clear and crisp. The eyeballs of the farsighted person are too short. A picture is focused behind the retina, instead of on the retina. Eyeglasses can correct both these problems by adding an extra lens to each eye.

1. When do most eye problems occur, and what can a nearsighted person see?







2. What do objects that are far away look like to a nearsighted person, and what causes this to happen?







3. What do close objects look like to a farsighted person and what do faraway objects look like?








Level#3

Most eye problems occur when the lens does not focus the "picture" exactly on the retina. A nearsighted person can see close objects clearly. Objects that are far away look fuzzy and blurred. Because the eyeballs are too long, a picture is focused in front of the retina, instead of on the retina. To a farsighted person, close objects look fuzzy, and faraway objects look clear and crisp. The eyeballs of the farsighted person are too short. A picture is focused behind the retina, instead of on the retina. Eyeglasses can correct both these problems by adding an extra lens to each eye. The extra lens move a picture backward or forward so that it is focused exactly on the retina. Contact lenses are small lenses that are worn on the cornea. Contact lenses provide the wearer with better overall vision than eyeglasses do.

1. Explain when most eye problems occur, and what a nearsighted person can and cannot see clearly.








2. Explain why a nearsighted person cannot see faraway objects clearly, and how a farsighted person sees.








3. Explain why a farsighted person cannot see close up objects clearly.
