Ask Marilyn: Have You Acquired Myopia?
Jim Castro of Helena, Montana, writes:
Marilyn: I'd like to add to your answer about myopia. (September 9, 2012) There is also a condition called pseudomyopia, which is caused by too many hours a day of close work, such as reading. The continual short-distance focusing eventually causes the muscles in the eye to shorten. The condition is irreversible. I started becoming nearsighted in college, and the Air Force doctor who prescribed my glasses explained the condition. For years, physicians didn't believe that myopia could be acquired like this. The thing that changed many doctors' minds was a study of U.S. Naval Academy graduates. One of their admission requirements was 20/20 vision, so no one in the entering class needed glasses. But by graduation, about 50% of the students needed glasses to correct nearsightedness.
Thank you for the information, Jim. We may not want to hear it, but it's better to be aware than in denial.
