Hyperopia: Understanding Farsightedness and How It’s Corrected

Learn what causes hyperopia (farsightedness), how it affects vision, and how Ontario optometrists diagnose and correct it.

What It Is 

Hyperopia, or farsightedness, is a common vision condition in which distant objects appear clearer than nearby objects. 
It occurs when light entering the eye focuses behind the retina, rather than directly on it. 
This can make reading, computer work, or other close tasks difficult — especially after long periods of concentration. 

 

Who It Affects / Causes 

Hyperopia can affect both children and adults and is often hereditary, though environmental factors can also play a role. 

It occurs when: 

  • The eyeball is too short, or 
  • The cornea is too flat (not curved enough) 

These differences cause the eye’s focusing system to work harder to bring near objects into focus. Over time, this effort can lead to eye strain, fatigue, and headaches. 

 

Symptoms to Watch For 

Common signs and symptoms of hyperopia include: 

  • Blurred vision when reading or doing close work  
  • Eye strain or discomfort  
  • Fatigue or headaches after prolonged focus  
  • Burning or aching eyes 
  • Difficulty maintaining focus on near tasks 
  • Poor reading ability or loss of concentration 

Children with uncorrected hyperopia may also experience reduced attention in class or avoid reading tasks, as the constant focusing effort can be tiring. 

 

How It’s Diagnosed 

Hyperopia can be detected during a comprehensive eye examination by an optometrist. 
Unlike basic sight tests, a full exam evaluates: 

  • Refraction and focusing ability 
  • Eye coordination and alignment 
  • Health of the retina and lens 

Because individuals with mild hyperopia may still read an eye chart easily, school screenings or vision tests may not detect it. 
Only an optometric exam can accurately measure the degree of farsightedness and determine if correction is needed. 

 

Treatment & Management 

Treatment depends on the degree of hyperopia and how much strain it causes. 

Eyeglasses or Contact Lenses 

  • The most common treatment for hyperopia 
  • Lenses redirect light rays so they focus directly on the retina 
  • May be prescribed for reading, computer use, or full-time wear, depending on the case 

Laser Vision Correction 

For eligible adults, refractive surgery such as LASIK, PRK, or lens implants can permanently reshape the cornea to improve focus. 
Your optometrist can assess whether you’re a suitable candidate. 

Lifestyle & Eye Care Tips 

  • Take regular breaks from close work (follow the 20-20-20 rule) 
  • Ensure proper lighting/posture when reading or using digital devices 
  • Maintain regular eye exams, especially for children and those over 40 

In mild cases, the eyes can often compensate naturally — but over time, especially with age, focusing effort may become more difficult. 

 

How Common Is It? 

Many people have some degree of hyperopia without realizing it. 
It is estimated that over half of the people who wear glasses do so for focusing problems related to hyperopia or presbyopia (the natural decrease in near focusing that comes with age). 

 

When to See Your Optometrist 

Book an exam if you experience: 

  • Eye strain or headaches after reading or screen use 
  • Difficulty focusing on near tasks 
  • Frequent squinting or rubbing your eyes 
  • Vision changes or fatigue while working close-up 
  • Teacher notices learning difficulties 

Optometrists can prescribe the right corrective lenses and help you maintain clear, comfortable vision for all distances.
