- Why Don't Doctors Do Something for People Who Are Nearsighted?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I've just bought another costly pair of eyeglasses. Why don't
- doctors do something for people who are nearsighted instead of just selling
- them glasses?
-

- ANSWER: For years, it is all we've known how to do to treat the symptoms of
- nearsightedness (myopia). We haven't been able to prevent or cure the problem
- itself.
- It usually begins with puberty and stabilizes in late adolescence. As
- the eye grows from infancy through late adolescence, the focal length of the
- eyeball and the shape of the lens may stay precisely balanced to maintain good
- vision. Fifteen to 20 percent of high school students become nearsighted by
- late adolescence because the lens and eyeball become unsynchronized in their
- growth.
- Currently, there is considerable debate as to whether environmental or
- genetic factors cause myopia. If the cause were determined, a cure or
- prevention could possibly be found. Back in 1813, it was noted that educated
- people who were applying for positions as officers training in the British
- army had a much higher incidence of nearsightedness than the farmers and
- fishermen who were serving as enlisted men. This seemed to indicate that
- people who had spent a good deal of their early years focusing on close
- objects were prone to nearsightedness.
- It is tempting to theorize that close work leads to myopia, and several
- studies have been conducted to try to determine if this is true. However, in
- one of the best studies of this theory, the two scientists who conducted it
- cannot agree on the significance of its results. This means that the subject
- needs more study before we can understand the reasons for myopia. Until that
- is accomplished, nothing can be done to prevent it. For now, your only
- options are to correct your myopia with glasses, contact lenses or a recently
- developed operation called radial keratotomy, which flattens the cornea and
- can correct nearsightedness in some cases.
