Nearsightedness or Myopia is very common; 25% of adults woldwide live with this vision defect. For these people close objects are clear, but distant object are blurred and difficult to distinguish. Nearsightedness happens when light has to focus in front of the retina, as opposed to on the retina, because of the eye's unusually long shape. Passed on genetically, the condition is often detected between the ages of 8 and 12 years old. Nearsightedness worsens during adolescence, and stabilizes in early adulthood. Although most often benign, nearsightedness when very severe implies a higher risk of detached retina.
