Hypermetropia

Hypermetropia (pronounced: /ˌhaɪpərmɪˈtrəʊpiə/), also known as farsightedness or long-sightedness, is a common refractive error where distant objects can be seen clearly, but close ones appear blurry. The term originates from the Greek words 'hyper' meaning 'over' and 'metropia' meaning 'measure of the eye'.

Causes

Hypermetropia is caused when the eye does not bend or refract light properly to a single focus to see images clearly. In hypermetropia, the eye is shorter than normal or has a cornea that is too flat, so that light focuses behind the retina.

Symptoms

Common symptoms of hypermetropia include difficulty focusing on near objects, eye strain, fatigue, and headaches after close work. A basic eye examination can confirm hypermetropia.

Treatment

Treatment options for hypermetropia include prescription glasses, contact lenses, and refractive surgery. Refractive surgery includes procedures like LASIK and PRK.

Related Terms

  • Myopia: Also known as nearsightedness, a condition where the eye sees near objects clearly, while distant objects appear blurry.
  • Presbyopia: A condition that affects the eye's ability to focus, often occurring with age.
