Can Myopia Be Reversed? Understanding What Treatments Can and Cannot Do

Author: Dr Val Phua
Estimated reading time: 24 minutes

Myopia, commonly called short-sightedness, causes distant objects to appear blurred while nearer objects may remain clear.

In most children and adults with established myopia, the eye has grown longer than its ideal optical length. Light entering the eye is therefore focused in front of the retina rather than directly on it.

Established axial myopia cannot currently be permanently reversed with routine treatment.

Current treatments can:

Correct blurred vision
Temporarily alter the eye’s focusing power
Slow further myopia progression
Reduce the amount of additional axial elongation
Reduce the final severity of myopia
Treat selected complications
Reduce dependence on glasses in suitable adults

Current treatments generally cannot:

Permanently shorten an elongated eye
Restore the eye to its original pre-myopic anatomy
Eliminate the future retinal and glaucoma risks associated with axial elongation
Guarantee that childhood myopia will stop progressing
Naturally return a high prescription to zero
Permanently cure myopia through eye exercises, vitamins or reduced spectacle wear

This distinction matters because the word reversal can refer to several different outcomes.

A treatment may make the prescription appear less myopic without reversing the structural elongation of the eye.

For example:

Glasses move the focus onto the retina while they are worn.
Contact lenses correct the focus at the surface of the eye.
Orthokeratology temporarily flattens the central cornea.
LASIK, SMILE and PRK permanently alter corneal focusing power.
An Implantable Collamer Lens adds focusing power inside the eye.
Atropine and myopia-control lenses aim to slow future progression.
Some red-light studies have reported temporary apparent axial shortening, but its mechanism, durability and long-term safety remain uncertain.

These treatments may provide excellent vision or clinically meaningful myopia control, but they do not all achieve the same biological result.

Myopia control is worthwhile even when it does not reverse existing myopia.

Every additional dioptre of myopia is associated with increasing lifetime risks of conditions such as myopic maculopathy, retinal detachment, open-angle glaucoma and cataract. Reducing the final degree of myopia may therefore provide long-term benefits beyond simply reducing spectacle thickness.

The Quick Answer

Can Childhood Myopia Be Reversed?

Established axial myopia usually cannot be reversed.

The eye does not normally return to its previous shorter axial length after it has elongated.

Treatment instead aims to:

Provide clear vision
Slow additional eye growth
Reduce the child’s final prescription
Reduce the likelihood of reaching high myopia
Preserve long-term eye health

Can the Prescription Become Less Myopic?

Yes, but the reason must be understood.

A prescription may become temporarily or apparently less myopic because of:

Relaxation of excessive focusing
Cycloplegic eye drops
Orthokeratology
Changes in corneal shape
A thicker choroid
Normal measurement variability
Changes in blood glucose
Cataract-related refractive fluctuation
Refractive surgery

A reduction in the measured spectacle prescription does not necessarily mean that axial myopia has been structurally reversed.

Can Myopia Be Corrected?

Yes.

Clear vision can usually be achieved with:

Spectacles
Contact lenses
Orthokeratology
LASIK
SMILE
PRK
ICL surgery
Lens-based surgery in selected adults

Correction changes where light focuses.

It does not necessarily change the underlying axial length.

Can Myopia Progression Be Slowed?

Yes.

Evidence-supported options for children include:

Myopia-control spectacle lenses
Dual-focus or multifocal soft contact lenses
Orthokeratology
Low-concentration atropine
Selected combination treatments
Increased outdoor time, particularly to reduce the risk of myopia developing
Repeated low-level red-light therapy in selected settings, although important long-term safety and standardisation questions remain

Systematic reviews and network meta-analyses support clinically meaningful slowing of axial elongation with atropine, orthokeratology, defocus spectacle lenses and specialised soft contact lenses. Treatment response varies considerably between children.

Can Myopia Return After Treatment Stops?

Progression may resume after myopia-control treatment is stopped.

The pattern depends on the treatment.

Atropine may be followed by rebound progression, particularly with higher concentrations or cessation at a younger age.
Orthokeratology’s corneal flattening reverses after lens wear stops.
Myopia-control spectacles stop providing their optical treatment when they are not worn.
Dual-focus contact-lens studies suggest that eye growth generally returns towards age-expected rates after cessation while retaining much of the benefit accumulated during treatment.
Red-light therapy may be followed by axial rebound, and long-term cessation data remain limited.

Treatment should therefore be stopped according to an individual monitoring plan rather than simply because the prescription appeared stable during one visit.

Understanding What Myopia Is

Where Should Light Normally Focus?

In an eye without significant refractive error, light from a distant object is focused onto the retina.

The retina converts light into electrical signals that are transmitted through the optic nerve to the brain.

What Happens in Myopia?

In myopia, distant light focuses in front of the retina when accommodation is relaxed.

This commonly occurs because:

The eye is too long
The cornea is relatively steep
The natural lens has excessive focusing power
Several factors occur together

What Is Axial Myopia?

Axial myopia occurs when the eye is longer than required for its optical power.

It is the most common structural basis of childhood myopia.

As the eye elongates:

The prescription becomes more negative
The retina and choroid are spread over a larger internal surface
The sclera may become thinner
The risk of myopia-related disease increases

Axial length is therefore an important measurement during childhood myopia management.

What Is Refractive Myopia?

Refractive myopia occurs when the cornea or natural lens has excessive focusing power relative to the eye’s length.

Possible causes include:

A steep cornea
Keratoconus
Lens-related refractive changes
Cataract
Medication or metabolic changes
Excessive accommodation

The treatment and prognosis depend on the cause.

What Is High Myopia?

High myopia is commonly defined as a spherical equivalent of −6.00 dioptres or more myopic.

Some patients have a long axial length despite a prescription that is less negative because of:

Previous refractive surgery
Lens surgery
Corneal shape
Internal optical factors

The spectacle prescription alone therefore does not completely describe structural myopia risk.

What Is Pathological Myopia?

Pathological myopia refers to structural changes that damage the back of the eye.

Possible complications include:

Myopic macular degeneration
Posterior staphyloma
Lacquer cracks
Myopic choroidal neovascularisation
Macular atrophy
Myopic traction maculopathy
Retinoschisis
Macular hole
Retinal detachment

High myopia and pathological myopia are related but are not identical.

A highly myopic eye may not yet show pathological changes, while structural disease can occasionally occur at less extreme prescriptions.

What Does “Reversing Myopia” Mean?

Correcting the Focus

Spectacles or contact lenses can correct the focus so that distant objects appear clear.

This is visual correction, not structural reversal.

The blurred distance vision returns when ordinary corrective lenses are removed.

Reducing the Measured Prescription

A treatment may reduce the number of negative dioptres measured during refraction.

This may occur through:

Temporary corneal reshaping
Refractive surgery
Relaxation of accommodation
Changes in choroidal thickness
Measurement variability

The eye may still retain the axial anatomy associated with myopia.

Shortening the Eye

True structural reversal would require the elongated eye to become permanently shorter without harming the retina, choroid, sclera or optic nerve.

No established routine treatment currently produces predictable, permanent and clinically substantial shortening of an axially myopic eye.

Preventing Future Progression

Slowing progression does not remove the myopia already present.

However, it may prevent a child from progressing, for example:

From −2.00 D to −6.00 D
From moderate to high myopia
From a shorter to a substantially longer axial length

This is clinically valuable even though the starting prescription remains.

Reducing Dependence on Glasses

LASIK, SMILE, PRK or ICL surgery can reduce spectacle dependence in suitable adults.

The patient may become plano or nearly plano while the eye remains anatomically long.

Refractive surgery therefore corrects myopia optically rather than removing the structural risks associated with axial elongation.

Long-term studies after refractive surgery demonstrate that axial elongation can continue independently of the corneal refractive correction.

Can Some Apparent Myopia Be Reversed?

Pseudomyopia

Pseudomyopia occurs when excessive accommodation temporarily increases the eye’s focusing power.

The eye behaves as though it is myopic even though the measured refractive error becomes less myopic or disappears after accommodation is relaxed.

Possible associations include:

Prolonged near work
Accommodative spasm
Stress
Excessive convergence
Certain neurological conditions
Medication effects
Eye trauma
Inflammation

Cycloplegic eye drops can help distinguish pseudomyopia from established myopia by temporarily relaxing accommodation.

Does Pseudomyopia Mean the Eye Is Healthy?

Not necessarily.

Pseudomyopia may coexist with true axial myopia.

A child may have:

A genuine myopic prescription
An additional accommodative component
Variable measurements from one examination to another

A cycloplegic refraction and, when appropriate, axial-length measurement help clarify the situation.

Can Pseudomyopia Resolve?

The accommodative component may improve after:

Appropriate optical correction
Reduced sustained accommodative effort
Treatment of accommodative spasm
Cycloplegic medication in selected cases
Management of associated binocular or neurological causes

This is one of the few situations in which an apparent myopic prescription may genuinely become less negative without corneal or intraocular surgery.

Pseudomyopia may also identify children at increased risk of later developing true myopia, so continued follow-up may still be appropriate.

Over-Minus Prescriptions

A child may appear more myopic when tested without adequate control of accommodation.

An excessive minus prescription may:

Produce clear distance vision
Increase accommodative demand
Hide hyperopia or pseudomyopia
Make future comparisons misleading

Cycloplegic refraction is particularly important in:

Younger children
Children with inconsistent prescriptions
Suspected pseudomyopia
Strabismus
Unexpected progression
Symptoms that do not match the measured refraction

Non-cycloplegic instruments systematically underestimate hyperopia in children and cannot replace cycloplegia when a definitive paediatric prescription is required.

Can Myopia Improve Naturally as a Child Grows?

A child’s refractive development is not perfectly linear.

Small fluctuations can occur because of:

Measurement variation
Accommodation
Corneal changes
Growth of the natural lens
Changes in anterior-chamber depth
Choroidal thickness
Time of day

A minor improvement at one visit does not prove that axial myopia has reversed.

Serial assessment should focus on:

Cycloplegic refraction
Axial length
Visual acuity
Corneal measurements
Treatment adherence
Change over several visits

Spectacles

Do Ordinary Glasses Reverse Myopia?

No.

Single-vision spectacles place the image on the retina while they are worn.

They do not normally shorten the eye or slow progression substantially.

Do Glasses Make Myopia Worse?

Correctly prescribed glasses do not weaken the eyes.

A child may notice blur more clearly after becoming accustomed to good vision, but the glasses have not created the underlying myopia.

Should Children Avoid Wearing Glasses?

No.

A child who needs correction should generally be provided with clear, appropriate vision.

Poor distance vision can interfere with:

Learning
Recognising faces
Sports
Mobility
Safety
Classroom participation

Does Undercorrection Slow Myopia?

Leaving a child deliberately blurred is not a reliable myopia-control strategy.

Clinical studies have produced mixed findings, but meta-analyses do not support routine undercorrection as an effective treatment. Some randomised evidence has suggested faster progression with undercorrection.

The practical approach is:

Correct vision appropriately.
Use an evidence-based myopia-control design when treatment is indicated.
Do not substitute blur for proper myopia management.

Myopia-Control Spectacle Lenses

Specialised spectacle lenses aim to provide clear central vision while exposing parts of the retina to optical signals intended to slow axial elongation.

Designs include:

Defocus Incorporated Multiple Segments lenses
Highly aspherical lenslet designs
Cylindrical or annular lenslet designs
Other peripheral-defocus or contrast-modifying designs

These lenses do not reverse established axial myopia.

They aim to reduce the rate at which additional myopia develops.

DIMS Spectacle Lenses

DIMS lenses contain a central distance-correction area surrounded by multiple segments that create simultaneous myopic defocus.

A two-year randomised trial found less refractive progression and axial elongation with DIMS lenses than with single-vision spectacles. Longer-term follow-up supports sustained treatment effects, although later phases did not retain a continuously randomised untreated control group.

Highly Aspherical Lenslets

Highly aspherical lenslet spectacles use multiple lenslets designed to create a volume of myopic defocus.

Randomised trials found slower refractive progression and axial elongation compared with single-vision spectacles. A five-year follow-up suggested sustained benefit, although the long-term comparison relied partly on an extrapolated control group.

Do These Lenses Make the Prescription Go Backwards?

Usually not.

A child may show:

Little or no progression
Slower axial elongation
Occasional small refractive improvement
Measurement fluctuation

The expected objective is slower worsening rather than permanent elimination of the existing prescription.

How Important Is Wearing Time?

The optical treatment is present only when the spectacles are positioned and worn appropriately.

Treatment effectiveness may be reduced by:

Inconsistent wear
Poor frame fit
Looking over the lenses
Incorrect optical centration
Outdated prescription
Damaged lenses

Soft Contact Lenses for Myopia Control

Dual-focus and multifocal soft contact lenses provide distance correction together with additional optical zones intended to slow eye growth.

They may provide:

Clear distance vision
Freedom from spectacles
Myopia-control treatment
Practical benefits for sports

Randomised trials support slower refractive progression and axial elongation with high-add multifocal or dual-focus contact lenses compared with single-vision contact lenses.

Do Dual-Focus Lenses Reverse Myopia?

No.

They correct the existing prescription while slowing additional progression.

The child still has myopia when the lenses are removed.

What Happens After Treatment Stops?

A seven-year dual-focus-lens study found that progression after treatment cessation returned towards expected age-related rates while the previously accumulated treatment benefit was retained. This does not guarantee the same response in every child or with every lens design.

Are Contact Lenses Safe for Children?

They can be safe when:

The child is suitable
Hygiene is reliable
Replacement schedules are followed
Water exposure is avoided
Overnight wear is avoided unless specifically prescribed
Regular corneal examinations are performed

Potential complications include:

Dryness
Inflammation
Corneal infiltrates
Infection
Corneal ulcer
Rare permanent visual loss

Contact-lens suitability should consider both the potential myopia-control benefit and the individual child’s ability to use lenses safely.

Orthokeratology

What Is Orthokeratology?

Orthokeratology uses specially designed rigid contact lenses worn during sleep.

The lenses temporarily reshape the front surface of the cornea.

After successful overnight wear, the child may see clearly during the day without spectacles or daytime contact lenses.

Does Orthokeratology Reverse Myopia?

It temporarily reverses part of the refractive effect by flattening the central cornea.

It does not permanently shorten the eye.

When lens wear stops:

The cornea gradually returns towards its previous shape.
The original myopic prescription returns.
Unaided distance vision becomes blurred again.

Studies confirm that corneal shape and refractive effects substantially recover after orthokeratology is discontinued.

Does Orthokeratology Slow Eye Growth?

Yes, in many children.

The two-year ROMIO randomised trial found less axial elongation in children wearing orthokeratology lenses than in children wearing single-vision spectacles.

The degree of control varies according to:

Age
Baseline myopia
Pupil size
Lens design
Treatment-zone position
Corneal shape
Adherence
Individual biological response

What Are the Risks?

Possible complications include:

Corneal staining
Lens binding
Inflammation
Light sensitivity
Glare
Halos
Reduced contrast
Microbial keratitis

Because the lenses are worn overnight, strict hygiene and prompt assessment of a painful red eye are essential.

Atropine Eye Drops

What Is Atropine?

Atropine is an antimuscarinic medication.

In diluted concentrations, it is used in many countries to slow childhood myopia progression.

It does not correct distance blur.

Children still require:

Spectacles
Contact lenses
Orthokeratology
Another form of optical correction

Does Atropine Reverse Myopia?

No.

Atropine aims to slow further refractive progression and axial elongation.

It does not normally return the existing prescription to zero.

Which Concentration Works Best?

Atropine demonstrates a concentration-dependent effect.

Higher concentrations generally provide stronger myopia control but cause more:

Pupil dilation
Light sensitivity
Near blur
Reduced accommodation
Risk of rebound after cessation

The LAMP trial found greater efficacy with 0.05% atropine than with 0.025% or 0.01%, with acceptable average tolerability in the studied population.

The appropriate concentration depends on:

Age
Rate of progression
Eye colour
Near-vision demands
Light sensitivity
Previous response
Availability
Regulatory considerations
Clinician experience

Is 0.01% Atropine Always Effective?

No.

Some children respond well.

Others continue progressing.

Efficacy also appears to vary between populations and studies.

Treatment should be judged using:

Cycloplegic refraction
Axial length
Age-expected eye growth
Adherence
Time on treatment

How Long Is Atropine Used?

Treatment may continue for several years.

The five-year LAMP extension found better cumulative control among children initially receiving continued 0.05% treatment. Most children assigned to treatment cessation after year three later met the study criteria for restarting atropine.

What Is Atropine Rebound?

Rebound means faster myopia progression after treatment is stopped.

It is influenced by:

Atropine concentration
Age at cessation
Baseline myopia
Previous progression rate
Duration of treatment
Individual response

Higher-concentration atropine has historically been associated with greater rebound after abrupt cessation.

Low-concentration regimens may still require retreatment.

Should Atropine Be Tapered?

There is no universal tapering schedule.

A recent comparative study found less refractive progression and axial elongation after gradual rather than prompt cessation of 0.01% atropine, but broader randomised evidence is still required before one method can be considered universally superior.

The child should be monitored after stopping, regardless of whether treatment is tapered.

Combination Treatment

Some children progress despite one treatment.

Possible combinations include:

Atropine with orthokeratology
Atropine with myopia-control spectacles
Atropine with dual-focus contact lenses
Optical treatment with behavioural intervention

Randomised trials and meta-analyses suggest that low-concentration atropine combined with orthokeratology can provide additional slowing of axial elongation compared with orthokeratology alone.

Combination treatment may also increase:

Cost
Complexity
Side effects
Treatment burden
Monitoring requirements

It should be selected for a reason rather than automatically prescribed to every child.

Repeated Low-Level Red-Light Therapy

What Is RLRL?

Repeated low-level red-light therapy involves looking into a device that delivers red light of a specified wavelength and power for short repeated sessions.

It has been studied primarily in children in East Asia.

Why Has It Been Described as Reversing Myopia?

Some studies have reported:

A less myopic refraction
Reduced axial elongation
Apparent axial shortening
Increased choroidal thickness

These findings have generated interest because apparent axial shortening is unusual in established childhood myopia.

Does Axial Shortening Prove Structural Reversal?

Not necessarily.

Measured axial length can be affected by:

Choroidal thickening
Diurnal variation
Measurement conditions
Retinal boundary changes
Short-term physiological responses

The choroid lies between the retina and sclera.

When it thickens, the measured distance to the retinal pigment epithelium may become shorter even though the scleral shell has not permanently contracted.

A small apparent axial reduction during active treatment should therefore not automatically be interpreted as permanent reversal of scleral elongation.

How Effective Is RLRL?

Recent meta-analyses have found substantial short-term slowing of axial elongation and refractive progression compared with single-vision spectacles. Some pooled analyses rank RLRL among the most effective currently studied interventions over approximately one year.

What Are the Uncertainties?

Important uncertainties include:

Long-term retinal safety
Device-specific irradiance and dosimetry
Safety across different commercial systems
Durability after stopping
Axial rebound
Generalisability beyond predominantly Chinese study populations
Optimal treatment duration
Appropriate retinal monitoring
Whether apparent shortening represents lasting structural change

Systematic reviews have reported short-term tolerability but also isolated retinal changes and case reports of reversible visual and OCT abnormalities. A 2026 review concluded that efficacy appears promising while safety validation, treatment standardisation and cessation data remain incomplete.

Can Parents Use an Ordinary Red Lamp?

No.

Consumer lamps, toys, laser pointers and unvalidated light devices should not be used as substitutes.

Ocular safety depends on:

Wavelength
Power
Beam profile
Retinal irradiance
Exposure duration
Pupil size
Device calibration
Treatment schedule

Looking directly into an inappropriate light source can damage the retina.

Outdoor Time

Can Outdoor Time Reverse Existing Myopia?

No.

Outdoor time does not normally make an elongated eye shorter or return an established prescription to zero.

What Can Outdoor Time Do?

Greater outdoor exposure is associated with a lower risk of developing myopia.

Randomised and prospective evidence supports increased outdoor time as a preventive strategy, particularly for children who are not yet myopic.

Does Outdoor Time Slow Established Myopia?

The effect is less consistent after myopia has already developed.

A 2024 meta-analysis found that increased outdoor time reduced myopia onset but did not produce a clear slowing effect among children who were already myopic.

Outdoor time should still be encouraged because of its:

General health benefits
Possible preventive benefit for siblings or pre-myopic children
Reduction of uninterrupted near work
Support for healthy daily routines

It should not replace established myopia-control treatment in a child who is progressing rapidly.

Near Work and Screens

Does Screen Use Permanently Damage the Eyes?

Ordinary screen use does not burn or permanently damage a healthy retina.

However, prolonged screen use may be associated with:

Sustained near focusing
Close viewing distance
Reduced blinking
Dryness
Less outdoor time
Longer uninterrupted near work

Will Stopping Screens Reverse Myopia?

No.

Removing screens does not shorten an already elongated eye.

Reducing prolonged, close and uninterrupted screen use may form part of a healthier visual routine, but it should not be presented as a cure.

Is Reading Harmful?

Reading is valuable and should not be discouraged.

The aim is to avoid excessively close and uninterrupted near work.

Practical habits include:

Maintaining a comfortable reading distance
Taking regular distance-vision breaks
Using adequate lighting
Alternating near work with other activities
Spending regular time outdoors
Avoiding prolonged recreational screen use immediately before sleep

No single break formula has been proven to reverse myopia.

Eye Exercises

Can Eye Exercises Reverse Axial Myopia?

No convincing evidence shows that eye exercises permanently shorten the eye or reverse established axial myopia.

A systematic review found limited to no efficacy of eye-exercise programmes for preventing or controlling myopia progression.

Can Exercises Help Other Conditions?

Exercises may be prescribed for selected binocular-vision problems such as:

Convergence insufficiency
Certain accommodative disorders
Selected postoperative or neurological conditions

Improvement in eye comfort or coordination does not mean that axial myopia has been cured.

The Bates Method

Claims that myopia can be reversed by:

Palming
Sun exposure
Avoiding glasses
Relaxing the eye muscles
Moving the eyes in specific patterns

are not supported by reliable evidence for structural myopia reversal.

Directly staring at the sun or a high-intensity light source can injure the retina and should never be attempted.

Vitamins and Supplements

No vitamin, antioxidant or supplement has been shown to reliably reverse ordinary axial myopia.

A balanced diet supports general eye health but does not shorten an elongated eye.

Supplements should not replace:

Accurate correction
Myopia-control treatment
Outdoor time
Appropriate follow-up
Retinal examination when indicated

Acupuncture and Massage

Current evidence does not establish acupuncture, periocular massage or acupoint exercises as methods that reverse axial elongation.

Massage near the eye also carries potential risks when performed forcefully, particularly after surgery or in an injured eye.

Pinhole Glasses

Pinhole apertures can temporarily improve clarity by blocking peripheral rays.

They do not:

Correct the full visual field
Reverse myopia
Shorten the eye
Provide safe general-purpose vision
Replace prescribed spectacles

Blue-Light-Blocking Glasses

Blue-light-filtering lenses do not reverse myopia.

They may alter perceived screen comfort for selected users, but they are not an established myopia-control treatment.

Sleeping More

Adequate sleep supports general health.

Sleep alone does not reverse axial myopia.

Poor sleep may coexist with heavy screen use and limited outdoor time, but correcting sleep habits should not be described as a cure.

LASIK, SMILE and PRK

Can Laser Eye Surgery Reverse Myopia?

Laser vision correction can permanently reduce the refractive error by reshaping the cornea.

After successful treatment, distant light is focused more accurately on the retina.

The patient may no longer require distance glasses.

However, the operation does not normally shorten the eye.

Does Retinal Risk Disappear After LASIK or SMILE?

No.

A highly myopic eye remains structurally long after its cornea is reshaped.

The patient may still have increased risks of:

Retinal tear
Retinal detachment
Myopic macular degeneration
Glaucoma
Myopic traction maculopathy

The new spectacle prescription may no longer reflect the original structural myopia.

The previous prescription and axial length should therefore remain part of the patient’s medical history.

Can Children Have Laser Surgery to Stop Myopia?

Routine elective refractive surgery is generally inappropriate while the eye and prescription are still developing.

Laser surgery:

Corrects the current prescription
Does not control continued axial growth
May be followed by recurrent myopia if the eye continues elongating

It is generally considered only after refractive stability in suitable adults, apart from exceptional medical circumstances.

Implantable Collamer Lens Surgery

An ICL is placed inside the eye in front of the natural lens.

It may correct:

Moderate myopia
High myopia
Astigmatism with a toric ICL

ICL surgery does not shorten the eye.

It adds optical power internally.

A highly myopic patient who sees clearly without glasses after ICL surgery still requires long-term retinal and glaucoma surveillance.

Refractive Lens Exchange and Cataract Surgery

Removing the natural lens and implanting an IOL can correct myopia.

This may be appropriate for:

Cataract
Selected older adults
Specific lens-related indications

It is not generally used as childhood myopia control.

Lens removal in a young highly myopic eye has important retinal, accommodative and intraocular-surgery considerations.

Why Myopia Control Matters Even Without Reversal

Reducing Final Myopia

A treatment that slows progression by a meaningful amount may reduce:

Final spectacle power
Lens thickness
Dependence on stronger correction
The probability of reaching high myopia
Lifetime structural risk

Every Dioptre Matters

A review modelling the risks and benefits of myopia control estimated that each additional dioptre of myopia is associated with increased risks of myopic maculopathy, open-angle glaucoma, posterior subcapsular cataract and retinal detachment. These are population estimates rather than precise predictions for an individual child.

Low Myopia Is Not Risk-Free

Myopia-related risk increases continuously.

There is no single threshold below which all structural risk disappears.

The absolute risk remains much lower with low myopia than with high myopia, but the objective is to reduce avoidable progression rather than wait until −6.00 D is reached.

Does Myopia Control Prevent All Complications?

No.

A child may still develop:

High myopia
Retinal tears
Myopic macular disease
Glaucoma
Cataract

Myopia control reduces risk by reducing expected progression.

It does not provide immunity.

Choosing a Myopia-Control Treatment

Age

Younger children generally have:

More potential years of progression
Faster average eye growth
Greater lifetime risk of reaching high myopia

Earlier treatment may therefore provide a larger cumulative benefit.

Rate of Progression

Treatment urgency increases when there is:

A prescription change of approximately −0.50 D or more in a year
Axial elongation faster than expected for age
Progression despite current treatment
Early-onset myopia
Strong family history
Significant baseline myopia

No single numerical threshold should replace clinical judgement.

Axial Length

Axial length helps distinguish:

True eye growth
Refractive fluctuation
Orthokeratology-related corneal change
Accommodation-related prescription change

It is particularly helpful when the spectacle prescription is temporarily altered by treatment.

Child and Family Preference

Treatment selection should consider:

Comfort
Appearance
Sports
Ability to use drops
Contact-lens hygiene
Cost
Access
Treatment burden
Follow-up reliability
Risk tolerance

Ocular-Surface Health

Contact-lens treatments may be unsuitable or require caution in children with:

Significant dry eye
Recurrent corneal inflammation
Poor hygiene
Severe allergy
Habitual eye rubbing
Reduced corneal sensation

What Is the Best Treatment?

There is no universally best treatment.

A 2025 network meta-analysis supported the efficacy of several interventions, including orthokeratology, atropine, highly aspherical lenslets and DIMS spectacles. More than 70% of included studies were conducted in Asian populations, so treatment effects may not be identical across every population.

The best option is one that:

Is evidence-based
Is safe for the individual child
Fits the family’s routine
Is worn or used consistently
Produces an acceptable measured response
Can be monitored properly

Monitoring Treatment

A myopia review may include:

Unaided visual acuity
Corrected visual acuity
Cycloplegic or non-cycloplegic refraction as appropriate
Axial length
Corneal topography
Slit-lamp examination
Pupil size
Accommodation
Eye alignment
Retinal examination
Assessment of adherence
Review of side effects

How Often Should a Child Be Reviewed?

A child receiving active myopia control is commonly reviewed approximately every six months.

More frequent review may be required:

Soon after contact-lens fitting
When atropine is started
When side effects occur
When progression is rapid
When the response is uncertain
After changing treatment

How Is Treatment Success Defined?

Success does not necessarily mean zero progression.

A successful treatment may result in:

Slower axial elongation than expected
Slower refractive progression
Avoidance of rapid progression
Reduced final myopia
Good visual function
Acceptable safety and adherence

What Is a Non-Responder?

A child may be considered to have an inadequate response when progression remains faster than expected despite:

Appropriate treatment
Good adherence
Correct prescription
Adequate wearing time
Reliable measurements

Possible responses include:

Confirming measurement quality
Checking adherence
Improving frame or lens fit
Increasing atropine concentration
Changing optical treatment
Combining treatments
Reviewing behavioural factors
Investigating unusual causes

When Should Treatment Stop?

Treatment cessation should consider:

Age
Pubertal stage
Recent progression
Axial-length trend
Age at myopia onset
Family history
Previous rebound
Current treatment
Side effects
Patient preference

A stable prescription over six months does not necessarily mean that treatment can safely stop.

Myopia in Adults

Can Adult Myopia Improve?

Small refractive changes may occur in adulthood because of:

Corneal change
Lens change
Accommodation
Pregnancy
Diabetes
Medication
Dry eye
Measurement variability

Established axial myopia usually remains.

Can Adult Myopia Still Progress?

Yes.

Progression can occur in:

Young adults
University students
People performing sustained near work
Highly myopic eyes
Pathological myopia
Eyes with posterior staphyloma

Longitudinal studies demonstrate that axial length may continue increasing in adults with high or pathological myopia.

When Should Adult Progression Be Investigated?

Assessment is appropriate when there is:

Rapid refractive change
Change in one eye only
Reduced corrected vision
Distortion
New corneal irregularity
Cataract
Diabetes
Medication change
Retinal disease
Symptoms of keratoconus

High Myopia and Lifelong Follow-Up

A highly myopic adult should consider periodic comprehensive examinations even after:

LASIK
SMILE
PRK
ICL surgery
Cataract surgery

The examination may include:

Eye pressure
Optic-nerve assessment
Macular OCT
Dilated retinal examination
Corneal assessment
Review of flashes and floaters

Frequently Asked Questions

Can −1.00 D Myopia Return to Zero Naturally?

Established axial myopia usually does not naturally return permanently to zero.

Small measured changes may occur through accommodation, testing variability or corneal and lens changes.

Can Mild Myopia Be Reversed More Easily Than High Myopia?

Mild myopia is easier to correct optically, but established axial elongation is not routinely reversible at either level.

Early mild myopia is an important opportunity to prevent progression to high myopia.

Can a Child Outgrow Myopia?

Myopia commonly stabilises later in adolescence or young adulthood.

Stabilisation means that progression slows or stops.

It does not mean that the existing prescription disappears.

Can Myopia Be Reversed Before It Fully Develops?

Children at risk of myopia may benefit from increased outdoor time and appropriate monitoring.

This is better described as delaying or preventing myopia onset rather than reversing myopia.

Can Atropine Make the Prescription Better?

A small improvement may appear during treatment, but the expected goal is slower progression.

A reduction in prescription should be checked against axial length and cycloplegic refraction.

Can Orthokeratology Reduce My Prescription?

Yes, temporarily.

The cornea returns towards its original shape after treatment stops.

Can Myopia-Control Glasses Be Worn Forever?

They may be worn as long as:

The prescription is appropriate
The child benefits
Progression risk remains
The lenses are comfortable
The treatment plan supports continued use

A transition to ordinary correction may be considered after sustained stability.

Can I Combine Atropine and Myopia-Control Glasses?

Yes, in selected children.

The evidence for every specific combination is less extensive than for atropine combined with orthokeratology, but combination treatment may be considered after reviewing response and treatment burden.

Can Myopia Return After LASIK?

The corneal correction is generally lasting, but the eye may continue changing.

Possible causes of recurrent blur include:

Continued axial elongation
Corneal regression
Dry eye
Cataract
Accommodation or presbyopia
Retinal disease

Does LASIK Make Retinal Detachment Less Likely?

No.

It does not reverse the elongated axial anatomy.

Can ICL Surgery Prevent Myopia Progression?

No.

It corrects the current refractive error.

Progressive axial change may still occur.

Are There Medications That Permanently Shrink the Eye?

No routinely established medication permanently shortens an axially myopic eye.

Can Cataract Surgery Remove Myopia?

The implanted IOL can target a less myopic or nearly plano refraction.

The operation does not remove the prior axial anatomy.

Can Diet Reverse Myopia?

No specific food or diet has been shown to reverse axial myopia.

Does Carrot Juice Improve Myopia?

Vitamin A is important for retinal function, but additional vitamin A does not reverse ordinary myopia in a person who is not deficient.

Excessive vitamin A can be harmful.

Can Myopia Be Reversed with Sunlight?

No.

Outdoor time may reduce myopia onset risk, but looking directly at the sun can permanently damage the retina.

Why Did My Child’s Prescription Improve by 0.25 D?

Possible explanations include:

Measurement variability
Different testing conditions
Accommodation
Cycloplegia
Corneal changes
Treatment effect
Normal biological fluctuation

The axial-length trend provides additional context.

Should Axial Length Become Shorter During Successful Treatment?

Not necessarily.

The usual target is slower elongation.

A small increase may still represent good control if untreated age-expected growth would have been greater.

What Is the Most Important Treatment Outcome?

The most meaningful outcome is reduction in cumulative axial elongation while maintaining:

Clear vision
Healthy corneas and retinas
Good adherence
Acceptable side effects
Normal childhood activities

When to Seek Prompt Eye Care

Myopia itself usually causes gradual distance blur.

Seek prompt assessment for:

New flashes of light
A sudden shower of floaters
A curtain or shadow
Sudden loss of vision
New distortion
A dark central spot
Severe eye pain
A red painful eye
Marked light sensitivity
Sudden double vision
Eye trauma
A painful red eye during contact-lens wear

These symptoms may indicate:

Retinal tear
Retinal detachment
Myopic macular disease
Infection
Acute glaucoma
Inflammation
Another ocular emergency

Could pseudomyopia be present?
How quickly is the eye elongating?
Is the progression faster than expected for age?
Which treatments are appropriate?
What is the evidence for each option?
What side effects should we expect?
Should atropine be used?
Are myopia-control spectacles suitable?
Are contact lenses or orthokeratology appropriate?
Should treatments be combined?
How frequently should axial length be measured?
How will treatment success be judged?
When should treatment be changed?
How and when should treatment eventually stop?
What retinal warning symptoms should the child know?

The Bottom Line

Established axial myopia usually cannot currently be permanently reversed.

Myopia treatment involves three different objectives:

Correction: moving the focus onto the retina so vision is clear
Control: slowing further refractive progression and axial elongation
Risk reduction: reducing the final severity of myopia and its lifetime complications

Spectacles, ordinary contact lenses, LASIK, SMILE, PRK and ICL surgery can correct vision.

They do not normally shorten the eye.

Orthokeratology temporarily reduces the refractive error by reshaping the cornea.

Its optical effect reverses when lens wear stops.

Myopia-control treatments include:

Defocus or lenslet spectacle designs
Dual-focus or multifocal soft contact lenses
Orthokeratology
Low-concentration atropine
Selected combination treatment

These treatments aim to slow additional progression, not eliminate existing axial myopia.

Outdoor time is particularly valuable for reducing the risk that myopia develops.

It is less reliable as a sole treatment once a child is already myopic.

Eye exercises, deliberate undercorrection, vitamins, massage, pinhole glasses and blue-light filters have not been shown to reverse axial elongation.

Repeated low-level red-light therapy has produced substantial short-term effects and apparent axial shortening in some studies. However, long-term safety, device standardisation, rebound and the biological meaning of axial shortening remain incompletely established.

The most important message is:

Myopia control should not be dismissed because it does not reverse the prescription already present. Preventing even part of a child’s future axial elongation can reduce the final degree of myopia and may meaningfully reduce the lifetime risk of retinal, macular, glaucoma and cataract complications.
