Risk factors
By Mayo Clinic staffCertain risk factors increase the risk of developing nearsightedness, such as:
- Family history. Nearsightedness tends to run in families. If one of your parents is nearsighted, your risk of developing nearsightedness is increased. The risk is even higher if both parents are nearsighted.
- Premature birth. Babies born prematurely are more likely to have eye conditions that can affect the shape of the eyes, increasing the risk of nearsightedness.
- Close work. Some studies have shown that there is an increased incidence of nearsightedness among people who do a lot of reading or other close work.
