Presbyopia

Presbyopia is the inability to focus on and clearly see objects that are at a normal reading distance or closer.

  • Causes

    Presbyopia is caused by an age-related, gradual loss of flexibility within the lens of the eye. Because the lens is less elastic, it cannot adequately change its shape to sharply focus on objects at close distances.

  • Definition

    Presbyopia is the inability to focus on and clearly see objects that are at a normal reading distance or closer.

  • Diagnosis

    A vision specialist will ask about your symptoms and medical history, and perform an eye exam. You will be asked to read materials at your normal reading distance while the doctor places different lenses in front of your eyes. This test determines the extent of your presbyopia.

  • Prevention

    Presbyopia is thought to be an inevitable part of the aging process. There are no current guidelines for preventing it or delaying its onset.

  • Risk Factors

    Age over 40 years increases your chance of getting presbyopia.

  • Symptoms

    Symptoms may include:

    • Having to hold lis at arm's length to focus on them
    • Blurred vision when reading

    • Eye fatigue, discomfort, or drowsiness when doing close-up work such as:

      • Reading
      • Needlepoint
      • Computer work

    Symptoms are often made worse by over-tiredness or stress.

  • Treatment

    Presbyopia is usually treated with corrective lenses. Lens options include:
