Certain risk factors may increase the likelihood of developing nearsightedness, such as:

  • Family history. Nearsightedness tends to run in families. If one of your parents is nearsighted, your risk of developing the condition is increased. The risk is even higher if both parents are nearsighted.
  • Reading. People who do a lot of reading may be at increased risk of myopia.
  • Environmental conditions. Some studies support the idea that a lack of time spent outdoors may increase the chances of developing myopia.
