Prevention
Although
nearsightedness (myopia) is easily treated, it cannot
be prevented, nor can you keep it from getting worse when you have it. It often
gets worse, sometimes rapidly, until the late teens or early 20s, when it
usually stabilizes. Nearsightedness does not improve as you get older.
Many people believe that too much close work, such as reading or
sitting too close to the television, causes nearsightedness. But there was
little evidence to support this belief. However, one study suggested that
people in professions that involve extensive reading have higher degrees of
nearsightedness.2
Special diets, eye exercises, and medicines will not treat or cure
nearsightedness.
