Practice 2: In Sight

Read the selection, and then answer the questions that follow.

(1) What causes myopia? You probably know that we see because light bounces off objects and into our eyes. In a normal eye, the light rays go through the lens and focus on the retina, the sensory membrane or sheet that lines the eye, to create images. In myopic eyes, the light focuses in front of the retina instead of directly on it. So nearsighted people can usually see really well up close, but they squint to try to see things far away.
(2) Often, nearsightedness is suspected if a kid has trouble seeing the chalkboard or whiteboard in school. Then a vision test is set up to diagnose perception. In other words, a doctor checks how well the person can read various sized letters at various distances.
(3) Early diagnosis is important because nearsightedness can be ameliorated with corrective visual devices, like glasses and contact lenses. These devices can't "cure" myopia, but they help a nearsighted person see distant objects more clearly. The lens of the glasses or contacts refocuses the light before it reaches the eye so it hits the retina where it should.
(4) Doctors can also do surgery to help some people who have myopia. Adults with myopia, whose glasses or contact prescription hasn't changed for at least a year, may be able to have a laser procedure that can clear up their problem.
(5) Nearsightedness affects men and women equally. People with a family history of myopia are more likely to develop it. And there's no way to prevent it. At one time people actually believed that reading too much or watching too much TV caused nearsightedness. Those activities can make your eyes tired, but they can't cause myopia.
