  • Farsightedness

    Farsightedness, also known as hyperopia, is a common type of refractive error where distant objects may be seen more clearly than objects that are near. However, people experience farsightedness differently. Some people may not notice any problems with their vision, especially when they are young. For people with significant farsightedness, vision can be blurry for objects at any distance, near or far.

    Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak.

  • Farsightedness

    • Crossed eyes (strabismus) in some children
    • Eye strain
    • Headache while reading
  • Farsightedness

    Diagnostic test:

    • Eye movement testing
    • Glaucoma testing
    • Refraction test
    • Retinal examination
    • Slit-lamp examination
    • Visual acuity
  • Farsightedness

    Treatment:

    Farsightedness is easily corrected with glasses or contact lenses. Surgery is available for correcting farsightedness in adults, and can be used for those who do not wish to wear glasses or contacts.

    Statistics:

    The number of people worldwide suffering from refractive errors is estimated to range from 800 million to 2.3 billion. Of these, around 153 million cases have not been corrected with contact lenses or glasses. In France, 39% of the population are estimated to suffer from myopia, 15% from astigmatism, 9% from hyperopia, and 26% to 30% from presbyopia.
