Hyperopia

Understanding Hyperopia

Hyperopia, commonly known as farsightedness, is a refractive error of the eye that affects a person’s ability to see close objects clearly. Unlike myopia (nearsightedness), where distant objects are blurry, hyperopia causes nearby objects to appear blurry while distant objects may be clearer.

Causes: Hyperopia occurs when the eyeball is too short or the cornea is too flat, causing light rays to focus behind the retina instead of directly on it. This can be due to genetic factors or structural differences in the eye.

Symptoms: Common signs of hyperopia include difficulty focusing on close-up tasks such as reading, eye strain, headaches (especially after close work), and occasional blurred vision at all distances.

Diagnosis: An eye care professional can diagnose hyperopia through a comprehensive eye examination, including tests to measure refractive error and assess visual acuity. These tests help determine the degree of hyperopia and the appropriate correction needed.

Treatment Options:

  • Eyeglasses: Prescription glasses with lenses that are convex (thicker in the middle and thinner at the edges) to help bend light rays to focus correctly on the retina.
  • Contact Lenses: Specifically designed to correct hyperopia, these lenses offer clear vision without the need for glasses.
  • Refractive Surgery: Procedures like LASIK or PRK can reshape the cornea to improve its focusing ability, reducing or eliminating the need for corrective lenses.
