Farsightedness (Hyperopia)

Farsightedness, also known as hyperopia, is a common refractive error where distant objects are seen more clearly than close ones. People with farsightedness may experience blurred vision when focusing on objects up close, leading to the need to squint in order to see clearly. This constant effort to accommodate can cause eyestrain, headaches, and discomfort around the eyes, particularly after extended periods of activities requiring near vision, such as reading or computer work.

Farsighted individuals often find themselves adjusting their focus to compensate for the inability of their eyes to adequately bend light to focus on nearby objects, a condition that affects millions worldwide.


Symptoms of farsightedness (hyperopia) may include:

  • Blurred vision when looking at close objects.
  • Difficulty focusing on near tasks such as reading or using a computer.
  • Eyestrain or discomfort, especially after prolonged periods of close work.
  • Headaches, particularly around the forehead or temples.
  • Squinting to see clearly up close.

These symptoms can vary in severity depending on the degree of hyperopia. Individuals with farsightedness often have clearer distance vision but struggle with tasks that require focusing on nearby objects. Regular eye exams are essential for early detection and management of hyperopia to maintain optimal vision and eye health.

Causes & Risk Factors:

Causes of farsightedness (hyperopia) may include:

  • Eyeball shape: Hyperopia often occurs when the eyeball is too short or the cornea is too flat, causing light to focus behind the retina instead of directly on it.
  • Genetic factors: A family history of hyperopia can increase the likelihood of developing the condition.
  • Age-related changes: As people age, the lens of the eye can lose flexibility, making it harder to focus on close objects.
  • Medical conditions: Certain health conditions, such as diabetes, can affect the focusing ability of the eyes and contribute to hyperopia.

These factors disrupt the normal focusing process of the eye, resulting in difficulty seeing objects up close without corrective lenses or treatment.

Testing & Diagnosis:

Testing and diagnosis of hyperopia (farsightedness) typically involve:

  • Visual Acuity Testing: This assesses clarity of vision at various distances using an eye chart, such as the Snellen chart or a near vision card, to determine if distant objects are seen more clearly than near ones.
  • Refraction Test: A refraction test helps measure the degree of hyperopia by determining the precise eyeglass prescription needed to correct vision. This involves looking through a series of lenses to find the combination that provides the sharpest vision.
  • Eye Health Examination: An eye health evaluation is conducted to assess the overall health of the eyes, including examining the retina, optic nerve, and other structures, to rule out any underlying conditions or complications associated with hyperopia.
  • Cycloplegic Refraction: In some cases, especially for children or individuals with significant hyperopia, a cycloplegic refraction may be performed. This involves using eye drops to temporarily paralyze the muscles that help focus the lens, providing a more accurate assessment of refractive error.

These tests and evaluations help eye care professionals accurately diagnose hyperopia and determine the most appropriate treatment options to improve vision.

Treatment Options

Treatment options for hyperopia (farsightedness) include:

  • Prescription Eyeglasses: Corrective lenses prescribed based on the degree of hyperopia can effectively refocus light onto the retina, improving near vision.
  • Contact Lenses: Depending on individual preferences and lifestyle, contact lenses can provide clear vision without the need for eyeglasses.
  • Refractive Surgery: Procedures such as LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy) reshape the cornea to adjust how light is focused onto the retina, reducing or eliminating the need for corrective lenses.
  • Orthokeratology (Ortho-K): This involves wearing specially designed contact lenses overnight to temporarily reshape the cornea, providing clear vision throughout the day without corrective lenses.
  • Reading Glasses: For individuals with mild hyperopia who primarily experience difficulty with close-up tasks, reading glasses may be prescribed to improve near vision.

The choice of treatment depends on factors such as the severity of hyperopia, age, lifestyle, and personal preferences. Regular follow-up visits with an eye care professional are important to monitor vision changes and adjust treatments as needed to maintain optimal visual acuity.
