Presbyopia
  • Presbyopia is an eye condition that usually
    happens to everyone later in the life. People
    suffering from presbyopia have a hard time
    focusing up close.While hyperopia is commonly
    known as farsightedness and myopia as
    nearsightedness, presbyopia might be called old
    sightedness. The term Presbyopia is derived from
    Greek and Latin origins that mean old
    eyes.However, presbyopia is generally seen in
    adults over the age of 40, the exact age of onset
    varies from person to person and depends on what
    type of eyeglass prescription (if any) the
    individual wore before its development.

Continue
  • Many people with myopia (near-sightedness) can
    read comfortably without eyeglasses or contact
    lenses even after age 40. Presbyopia may seem to
    appear immediately, but the actual loss of
    flexibility in the lens takes place over a period
    of years.Presbyopia is not a disease, and it
    cannot be prevented. There is no cure available
    for it, but there are many ways to improve near
    vision.

4
Causes of Presbyopia
  • This disease is caused by the aging process.
    When one is younger, the lens of the eye is
    flexible and changes its shape in order to focus
    up close this process is called
    accommodation.  With age, the lens becomes
    progressively more rigid and loses its ability to
    accommodate.Trauma, occupation, and lifestyle
    are some of the factors which are responsible,
    but presbyopia is a natural part of the aging
    process and will eventually happen to everyone.

5
Prognosis of Presbyopia
  • By definition, presbyopia is not a disease it
    can always be corrected by glasses or contact
    lenses and will never affect distance vision. It
    worsens over time.

6
Signs Symptoms of Presbyopia
  • Symptoms may include
  • Eye strain
  • Headaches
  • Blurred vision at normal reading distances
  • Eye fatigue or general fatigued feeling,
    especially at the end of the day
  • Squinting to focus on near objects
  • A decrease in ability to focus on near objects
