Age

Age is the greatest risk factor for presbyopia. Almost everyone experiences it after age 40.

Premature presbyopia

However, some people can develop presbyopia earlier than age 40 as a result of certain diseases or certain drugs. Premature presbyopia can be an indicator that you have a disease you may not be aware of. Risk factors for premature presbyopia include:

  • Other medical conditions. Being farsighted or having certain diseases, such as diabetes, multiple sclerosis or cardiovascular diseases, can increase your risk of premature presbyopia.
  • Drugs. Certain prescription and nonprescription drugs can decrease the focusing ability of your eye. They include antidepressants, antihistamines and diuretics.
