Hyperopia (Farsightedness)

Hyperopia, commonly called farsightedness, is a refractive error where light focuses behind the retina instead of on it. Contrary to what the name suggests, hyperopia doesn't always mean distance vision is good—it means the eye must work harder to focus, especially for near objects. This extra effort can cause eye strain, headaches, and fatigue.

How Hyperopia Works

In hyperopia:

• The eyeball is too short, OR
• The cornea/lens doesn't have enough focusing power
• Light focuses behind the retina
• The eye must accommodate (focus harder) to see clearly

The Role of Accommodation

Young eyes can flex their internal lens to add focusing power. This allows many hyperopes to see clearly but at a cost:

• Constant focusing effort required
• Eye fatigue and strain
• Headaches, especially after near work
• Symptoms worsen with age as accommodation decreases

Symptoms

Vision-Related

• Blurry near vision (most common complaint)
• Distance vision may also be affected in higher degrees
• Difficulty reading or doing close work
• Squinting to see clearly
• Words appear to "swim" after prolonged reading

From Accommodation Strain

• Eye strain and fatigue
• Headaches—often frontal or around eyes
• Burning or aching eyes
• Difficulty concentrating on near tasks
• Avoidance of reading or close work

In Children

• Difficulty with reading and schoolwork
• Short attention span for near tasks
• Rubbing eyes frequently
• Turning or tilting head when reading
• May be mistaken for learning problems

Types and Degrees

By Severity

Classification	Diopters (D)	Typical Presentation
Low	Up to +2.00	Often compensated, may have strain
Moderate	+2.00 to +5.00	Usually needs correction
High	> +5.00	Needs correction, higher complication risk

By Type

Simple Hyperopia

• Normal variation in eye size
• Most common type

Pathologic Hyperopia

• Due to disease or structural abnormality
• Less common

Functional Hyperopia

• From paralysis or weakness of accommodation
• Rare

Diagnosis

Eye Examination

• Visual acuity testing
• Refraction—determining glasses prescription
• Cycloplegic refraction—essential, especially in children
  • Dilating drops relax accommodation
  • Reveals true hyperopia (often more than manifest refraction)

Why Cycloplegic Refraction Matters

Without dilating drops, a young hyperope can accommodate and hide their true prescription. Cycloplegic drops:

• Paralyze the focusing muscle temporarily
• Reveal the full amount of hyperopia
• Essential for accurate prescriptions in children

Treatment

Not sure whether you need glasses or contacts? Our glasses and contacts guide can help you decide.

Glasses

• Convex (plus) lenses converge light
• Reduces or eliminates need for accommodation
• Relieves strain and fatigue
• May be needed full-time or just for near work

Contact Lenses

• Soft or rigid options available
• Good for active lifestyles
• May be preferred cosmetically
• Require proper care

Refractive Surgery

For stable adult hyperopia:

• LASIK—can correct low to moderate hyperopia
• PRK—alternative procedure
• Less predictable than myopia surgery
• Not all hyperopes are good candidates

Special Considerations

Hyperopia and Angle Closure

Hyperopia and Strabismus

In children, uncorrected hyperopia can cause:

• Accommodative esotropia—eye turns inward when focusing
• Treating with glasses often straightens the eyes
• Early detection and treatment important

Age-Related Changes

As presbyopia develops (starting around age 40):

• Hyperopes lose their compensating accommodation
• Distance AND near vision become blurry
• Often need glasses earlier than myopes
• May need bifocals or progressives

Hyperopia in Children

Why It's Often Missed

• Children have strong accommodation
• May pass vision screening
• Symptoms attributed to other causes (behavior, attention)
• Cycloplegic exam needed to detect

Importance of Detection

Uncorrected hyperopia can lead to:

• Accommodative esotropia (crossed eyes)
• Amblyopia (lazy eye)
• Learning difficulties
• Avoidance of reading

Treatment in Children

• Glasses are primary treatment
• May not need full correction (some accommodation normal)
• Regular monitoring as eyes grow
• Treatment of any associated strabismus or amblyopia

Living with Hyperopia

When to Wear Glasses

Depends on degree and symptoms:

• Mild: May only need for prolonged near work
• Moderate/High: Usually full-time wear
• With strabismus: Full-time wear essential

Managing Eye Strain

Even with correction:

• Take breaks during near work
• Ensure good lighting
• Follow 20-20-20 rule
• Keep prescription up to date

Frequently Asked Questions

If I'm farsighted, why is my distance vision blurry too?

In higher degrees of hyperopia, accommodation can't fully compensate even for distance. Also, as you age and lose accommodative ability, distance blur becomes more noticeable.

Will my child outgrow hyperopia?

Children are often hyperopic, and the eye typically grows toward normal (emmetropia) during childhood. Some hyperopia may decrease, but significant hyperopia usually persists.

Why do I need stronger glasses for reading than for distance?

Near vision requires more focusing power. Your reading prescription adds to your distance prescription to provide additional help for close work.

Can LASIK fix farsightedness?

LASIK can correct low to moderate hyperopia, but it's less predictable than myopia correction. Higher hyperopia may not be fully correctable. Consult a refractive surgeon for evaluation.

Why did my doctor dilate my child's eyes?

Dilation (cycloplegic refraction) is essential in children to get an accurate measurement of hyperopia. Without it, the child's focusing muscles mask the true prescription.

Is hyperopia hereditary?

There's a genetic component—children of hyperopic parents are more likely to be hyperopic. However, environmental factors also play a role in eye development.
