Why, Eye, Why - The Story Behind Corrective Lenses
By Jennifer Kenny

¹     All eyes have certain parts. Eyes can be different in certain respects as well. Do you have blue eyes, or brown eyes, or even hazel eyes? That colored part of the eye is the iris. The center part, which appears to be a black dot, is called the pupil and it lets light into the eye. The cornea is the clear tissue and it helps the eye focus. Finally, the retina is at the very back of the eye.

²     When all of these parts work correctly, a person can see. The eyes capture an image which goes to the brain to be interpreted. The bending of light rays, or refracting, is important so the image can be focused sharply on your retina. When there's a problem with vision, it is often related to refracting. Many adults now get laser surgery to fix some of these problems. However, laser surgery is not right for children because they still have growing to do. Instead, corrective lenses are often the tools to correct the problems so they can see most clearly.

³     Two of the most common refractive problems are nearsightedness and farsightedness. James is nearsighted. He has no problem reading his book, but he can't see the blackboard very well. On the other hand, his father is farsighted. He can see the street signs clearly, but he can't see the words well on the newspaper right in front of him. Both use eyeglasses, although different ones, to correct their vision. In nearsightedness and farsightedness, the image is not correctly focused on the retina. In nearsightedness, the image is focused in front of the retina, but in farsightedness, the image is focused behind.
