How Often Should Children Have Their Eyes Checked? A Guide for Parents

Author: Dr Val Phua
Estimated reading time: 22 minutes

Children should have age-appropriate eye and vision screening from infancy, with further examinations during the preschool and school years.

However, there is no single examination interval that is appropriate for every child.

How often a child’s eyes should be checked depends on:

Age
Symptoms
Previous screening results
Spectacle prescription
Myopia progression
Eye alignment
Amblyopia risk
Prematurity
Developmental or neurological conditions
Family history
Contact-lens use
Previous eye disease or surgery

For a healthy child with no symptoms or known risk factors, recurrent age-appropriate vision screening may be sufficient.

The American Association for Pediatric Ophthalmology and Strabismus recommends:

Eye and visual assessment during infancy
Screening during the toddler and preschool years
Formal visual-acuity testing when the child can cooperate
Repeat vision screening every one to two years after five years of age

Children who fail screening, cannot complete screening reliably or have symptoms or risk factors should receive a comprehensive eye examination rather than simply waiting for the next routine screen.

In Singapore, the Health Promotion Board provides vision screening in preschools and through primary-school health services. These programmes are valuable safety nets, but they should not delay an earlier examination when parents, teachers or healthcare professionals have concerns.

Children who already have an eye condition usually require more frequent reviews.

For example:

A child receiving amblyopia treatment may need review within several weeks.
A child undergoing myopia-control treatment is commonly assessed approximately every six months.
A child with rapidly changing vision, strabismus or another active condition may need earlier follow-up.
A child with stable glasses and otherwise healthy eyes may be reviewed every six to twelve months, depending on age and prescription.

The most important principle is:

Do not wait for a scheduled screening when a new symptom or visible abnormality develops.

The Quick Answer

How Often Should a Healthy Child Have an Eye Test?

A practical general schedule is:

Birth and infancy: eye and red-reflex assessment during routine healthcare visits
One to three years: age-appropriate visual assessment or instrument-based screening
Three to five years: formal vision screening at least once, preferably with each eye tested separately
Five years and older: repeat screening approximately every one to two years
At any age: comprehensive examination when symptoms, risk factors or an abnormal screening result are present

Different countries and healthcare organisations use different schedules.

Research has not identified one globally accepted screening frequency that is superior for every population. Screening programmes also differ in their equipment, referral criteria and access to follow-up care.

Does Every Child Need a Comprehensive Eye Examination Every Year?

Not necessarily.

The AAPOS Choosing Wisely guidance states that annual comprehensive examinations are not required for every healthy, asymptomatic child who consistently passes properly conducted recurrent vision screening.

Comprehensive examinations remain appropriate when:

Screening is failed
Screening cannot be completed
Symptoms are present
Risk factors are present
The child has an existing eye condition
Parents or teachers remain concerned

This distinction helps avoid both extremes:

Assuming that school screening replaces all eye care
Assuming that every healthy child requires specialist examination every year

What if My Child Wears Glasses?

Children wearing glasses generally need more frequent reviews than children with no known eye condition.

A practical interval is commonly:

Every three to six months for very young children, changing prescriptions or active amblyopia
Every six to twelve months for many stable school-aged children
Earlier when the child reports blur or the prescription appears to be changing

The exact schedule depends on:

The child’s age
Type and strength of prescription
Difference between the two eyes
Eye alignment
Visual acuity
Myopia progression
Whether the glasses are part of amblyopia treatment

How Often Should a Child with Myopia Be Checked?

A child with myopia is commonly reviewed approximately every six months, particularly when:

Myopia is progressing
Axial length is being monitored
Atropine is being used
Myopia-control spectacles are worn
Dual-focus contact lenses are worn
Orthokeratology is used

A 2024 UK and Ireland consensus recommended six-monthly axial-length monitoring after a myopia-control intervention has begun. More frequent appointments may be required during initial lens fitting, when side effects occur or when progression is faster than expected.

How Often Should a Child with Amblyopia Be Checked?

Amblyopia treatment usually requires review over weeks or months rather than once a year.

Follow-up assesses:

Vision in each eye
Glasses wear
Patching or atropine adherence
Improvement in the amblyopic eye
Vision in the better eye
Eye alignment
Need to increase, reduce or stop treatment

Clinical trials of amblyopia treatment frequently reassess children after approximately six to ten weeks because useful visual change may occur over this period. The exact interval should be individualised.

How Often Should a Child with Strabismus Be Checked?

The schedule depends on:

Age
Type of strabismus
Frequency of the eye turn
Control
Visual acuity
Amblyopia
Glasses prescription
Double vision
Whether surgery has been performed or planned

A young child with newly diagnosed strabismus may need review within weeks or a few months.

An older child with stable alignment and equal vision may be reviewed less frequently.

Strabismus should not simply be observed indefinitely without confirming that both eyes are developing useful vision.

A Practical Eye-Check Schedule by Age

Newborn to Three Months

What Should Be Checked?

The newborn eye assessment commonly includes:

External appearance of the eyes
Eyelid position
Pupil shape
Red reflex
Eye size
Obvious structural abnormalities
Relevant family and birth history

The red reflex should generally be present and reasonably symmetrical in both eyes.

An absent, dull, white or markedly unequal reflex requires prompt investigation.

When Should Parents Seek Earlier Assessment?

Seek prompt assessment for:

A white pupil
A cloudy cornea
An unusually large eye
Marked light sensitivity
Constant tearing
An abnormal pupil
An obvious structural abnormality
A strong family history of retinoblastoma or serious congenital eye disease

Infants who do not begin fixing or following appropriately after the early months should also be assessed. AAPOS recommends referral when an infant is not tracking well after approximately three months of age.

Three to Twelve Months

What Is Assessed During Infancy?

Healthcare professionals may observe:

Fixation
Following behaviour
Eye alignment
Eye movements
Pupil responses
Red reflexes
Visual attention
Whether both eyes appear to be used equally

A baby does not need to identify letters or pictures for useful assessment.

Are Brief Eye Turns Normal in Babies?

Eye control may appear immature during the earliest weeks.

However, persistent or recurrent misalignment should not automatically be dismissed.

Assessment is particularly important when:

The turn is constant
The same eye always turns
The appearance persists beyond early infancy
The baby has abnormal visual behaviour
An unusual head position develops
The eye turn is associated with a white pupil or abnormal red reflex

Twelve to Thirty-Six Months

How Can a Toddler Be Screened?

Testing may include:

Visual behaviour
Eye alignment
Pupil examination
Red-reflex examination
Photoscreening
Handheld autorefraction
Picture or matching tests
Objective refraction when indicated

Instrument-based screening is useful for toddlers who cannot yet perform a conventional visual-acuity test.

It may identify risk factors such as:

High myopia
High hyperopia
Astigmatism
Unequal prescriptions
Strabismus
Media opacity

Does Photoscreening Replace an Eye Examination?

No.

Photoscreening identifies children at increased risk and refers them for further assessment.

It does not directly measure all aspects of vision or exclude every retinal, optic-nerve or binocular-vision disorder.

A meta-analysis of photoscreening in children younger than three found that approximately 13% were referred, 8% could not be screened and the pooled positive predictive value was about 56%. Screening performance varied substantially between studies and programmes.

What if My Toddler Cannot Complete the Test?

An untestable result should not automatically be treated as a pass.

The child may require:

A repeat screen
An instrument-based test
A comprehensive eye examination
Referral based on age, risk factors and observations

Updated preschool-screening recommendations emphasise follow-up systems for children who fail or cannot complete screening.

Three to Five Years

Why Is the Preschool Period Important?

Preschool screening aims to detect conditions that may interfere with visual development, including:

Amblyopia
Strabismus
Unequal refractive error
High refractive error
Cataract
Ptosis
Other causes of reduced vision

Amblyopia is often asymptomatic because the stronger eye compensates.

The preschool period provides an important opportunity to begin treatment while the visual system remains highly adaptable.

How Often Should Preschoolers Be Screened?

A child should have at least one reliable monocular visual-acuity or instrument-based screening assessment during the preschool years.

Screening may occur more than once through:

Well-child visits
Preschool programmes
Community screening
Eye-care visits

AAPOS recommends age-appropriate visual-acuity screening from 36 months onward when the child can cooperate.

What Are Typical Screening Thresholds?

AAPOS screening guidance uses age-based thresholds:

Between 36 and 47 months, the child should identify most symbols on the 20/50 line
Between 48 and 59 months, the child should identify most symbols on the 20/40 line
From five years onward, most symbols on the 20/32 line should be identified

These are screening referral thresholds rather than final diagnostic definitions.

What if One Eye Sees Better Than the Other?

A difference between the eyes can be important even when both eyes appear to pass a broad screening threshold.

Unequal vision may indicate:

Anisometropic amblyopia
Strabismic amblyopia
Corneal or lens disease
Retinal or optic-nerve disease
Variable cooperation

A comprehensive assessment may be needed.

Five Years and Older

How Often Should School-Aged Children Be Screened?

For children aged five and older without known risk factors, AAPOS recommends repeat vision screening every one to two years.

Screening commonly includes:

Distance visual acuity in each eye
External inspection
Eye alignment
Pupil and red-reflex assessment
Further tests according to the screening programme

Why Is Repeat Screening Needed?

A normal preschool result does not prevent a later condition from developing.

Myopia commonly begins during the school years.

Other changes may include:

Increasing astigmatism
Decompensating strabismus
Eye injury
Contact-lens-related disease
Retinal or neurological disease
Medication-related effects

Is School Screening Enough?

School screening is valuable, but it has limitations.

It may not fully assess:

Cycloplegic prescription
Intermittent strabismus
Eye strain
Near-vision symptoms
Corneal disease
Retinal or optic-nerve health
Myopia progression
Axial length
Contact-lens safety

Parents should arrange further assessment when symptoms persist despite a passed screening result.

Teenagers

How Often Should Teenagers Be Checked?

A teenager with no symptoms, no glasses and consistently normal screening may continue age-appropriate screening every one to two years.

More frequent reviews are appropriate for teenagers with:

Myopia
Rapidly changing prescriptions
Contact lenses
Keratoconus risk
Eye allergy and vigorous rubbing
Diabetes
Previous eye surgery
Glaucoma risk
Retinal disease
Visual requirements for driving or occupation

Does Myopia Stop When a Child Becomes a Teenager?

Not necessarily.

Myopia may continue progressing through the teenage years and sometimes into early adulthood.

A teenager should continue follow-up until the prescription and, where measured, axial length have demonstrated meaningful stability.

Eye Screening in Singapore

Preschool Screening

Singapore’s Health Promotion Board provides growth, developmental and vision screening for children in Kindergarten 1 and Kindergarten 2 through participating preschool services.

Children who miss school-based screening may be directed to the Student Health Centre.

Primary-School Screening

HPB’s Youth Preventive Health and Dental Services provides health screening for Primary 1 to Primary 6 students, including vision assessment.

School screening commonly assesses distance visual acuity using a Snellen-type chart.

HPB guidance indicates that children with vision below specified referral thresholds may require further assessment.

Does Singapore School Screening Replace Eye-Clinic Follow-Up?

No.

A child who already has:

Myopia
Amblyopia
Strabismus
An eye disease
Contact lenses
Myopia-control treatment

should continue the review schedule recommended by the treating eye-care professional.

Parents should also arrange examination when they observe a problem between school screenings.

Which Children Need More Frequent Examinations?

Children Who Wear Glasses

The frequency depends on why the glasses were prescribed.

A younger child may need earlier review because:

Visual development is active
The prescription may change
The glasses may affect alignment
Amblyopia may be present
The frame may quickly become poorly fitted

A school-aged child with a stable prescription may be reviewed every six to twelve months.

Earlier review is appropriate when:

The child reports blur
The child sits closer to the board
Headaches develop
The glasses are no longer worn comfortably
The eye begins turning
The child closes one eye
Academic or visual behaviour changes
The lenses or frame are damaged

Children with Myopia

Myopia management involves more than checking whether the child can still read the chart with glasses.

A follow-up may assess:

Unaided visual acuity
Corrected visual acuity
Refraction
Axial length
Eye alignment
Retinal health
Treatment adherence
Side effects
Time outdoors
Near-work habits

Stable Low Myopia

A child with apparently stable myopia may still require review every six to twelve months.

The apparent absence of complaints does not prove that the prescription or axial length has stopped changing.

Progressive Myopia

Review approximately every six months is commonly appropriate.

More frequent review may be required when:

The prescription changes rapidly
Axial length is increasing faster than expected
Treatment has recently started
Adverse effects occur
Orthokeratology lenses do not fit appropriately
Contact-lens hygiene is poor

Consensus recommendations support six-monthly axial-length monitoring during active myopia management when this measurement is available.

Children Receiving Low-Dose Atropine

Follow-up may assess:

Vision
Refraction
Axial length
Pupil size
Light sensitivity
Near vision
Allergic or local reactions
Adherence

The first follow-up may be earlier than six months when:

A new concentration is started
Side effects occur
The child has difficulty with reading
The treatment regimen changes

Atropine should not be continued indefinitely without review of progression and tolerability.

Children Wearing Myopia-Control Spectacles

A review may determine:

Whether the prescription remains accurate
Whether the frame position is appropriate
Whether the child looks through the intended treatment zones
Whether the lenses are worn consistently
Whether myopia continues progressing

Poor frame fit may reduce the practical effectiveness of some lens designs.

Children Wearing Soft Contact Lenses

An initial follow-up may be required soon after fitting.

Long-term review assesses:

Vision
Lens fit
Corneal health
Tear film
Hygiene
Replacement schedule
Myopia progression when applicable

The child should be assessed earlier for:

Redness
Pain
Light sensitivity
Discharge
Sudden blur
Reduced contact-lens tolerance

Children Using Orthokeratology

Orthokeratology requires structured follow-up because lenses are worn overnight.

Reviews may be more frequent during initial fitting and may later occur every three to six months depending on the child and practice protocol.

Assessment may include:

Unaided vision
Refraction
Corneal topography
Lens fit
Corneal staining
Lens hygiene
Axial length
Myopia progression

A painful red eye in an orthokeratology wearer requires prompt assessment.

Children with Amblyopia

Amblyopia is treated during a period when visual development remains responsive.

Waiting a full year between visits during active treatment would usually be inappropriate.

Reviews may be arranged every several weeks to a few months depending on:

Age
Severity
Cause
Treatment
Rate of improvement
Adherence
Vision in the better eye

The treatment plan may include:

Glasses
Patching
Atropine
Bangerter filters
Strabismus management
Removal of a visual obstruction

The Amblyopia Preferred Practice Pattern and randomised clinical trials support active monitoring and adjustment according to measured response.

Children with Strabismus

Follow-up assesses:

Alignment at distance and near
Frequency of the eye turn
Control
Vision in each eye
Amblyopia
Stereoacuity
Prescription
Abnormal head posture
Symptoms of double vision

Appointments may be more frequent when:

The child is young
The turn is newly diagnosed
Glasses were recently prescribed
Patching is being used
Surgery is being planned
Alignment changes suddenly
The child develops double vision

Children Born Prematurely

Premature infants may require specific neonatal retinal screening.

Longer-term childhood follow-up may also be needed because premature children have increased risks of:

Refractive error
Strabismus
Amblyopia
Retinal abnormalities
Neurological visual impairment

The appropriate schedule depends on:

Gestational age
Birth weight
Retinopathy-of-prematurity history
Neurological development
Previous treatment

A child who completed neonatal retinal screening may still require later visual-development assessment.

Children with Developmental or Neurological Conditions

A lower threshold for comprehensive assessment is appropriate in children with:

Cerebral palsy
Down syndrome
Autism spectrum disorder
Developmental delay
Hydrocephalus
Seizure disorders
Hearing impairment
Brain injury
Genetic syndromes
Craniofacial abnormalities

These children may have increased rates of:

Refractive error
Strabismus
Oculomotor abnormalities
Cerebral visual impairment
Optic-nerve abnormalities

The examination should be adapted rather than abandoned when conventional testing is difficult.

Children with a Family History

Earlier or more frequent examinations may be appropriate when close relatives have:

Amblyopia
Childhood strabismus
High myopia
Keratoconus
Congenital cataract
Congenital glaucoma
Retinal dystrophy
Retinoblastoma
Significant inherited eye disease

A family history does not mean that the child will necessarily develop the condition.

It may change the threshold for examination or monitoring.

Children with Diabetes

Children with diabetes require retinal screening according to:

Type of diabetes
Age
Pubertal status
Duration of disease
National or specialist guidelines

The retinal schedule is separate from routine refractive or school vision screening.

New blur may also result from fluctuating glucose levels and should be assessed in context.

Children Using Steroid Medication

Long-term or repeated steroid use may increase the risk of:

Raised eye pressure
Cataract
Other ocular effects

The need for eye-pressure and lens monitoring depends on:

Steroid type
Dose
Duration
Route of administration
Individual response
Family history of glaucoma

Children After Eye Surgery

Postoperative follow-up is determined by the procedure.

A child may need frequent early reviews after:

Cataract surgery
Glaucoma surgery
Strabismus surgery
Retinal surgery
Corneal surgery
Eye-trauma repair

Long-term follow-up may remain necessary even after apparently successful surgery because the child’s eye and visual system continue developing.

Children with One Useful Eye

A child with significantly reduced vision in one eye requires:

Regular monitoring of the better eye
Appropriate spectacle correction
Protective eyewear advice
Prompt assessment of any new symptom
Education for the child, family and school

The better eye should not be assumed to remain healthy indefinitely without appropriate care.

Screening and Comprehensive Examination Are Not the Same

What Does Screening Usually Check?

Screening may assess:

Distance visual acuity
Eye appearance
Alignment
Red reflex
Photoscreening or autorefraction

It is designed to be:

Fast
Repeatable
Suitable for large numbers of children
Sensitive to clinically important risk

What Does a Comprehensive Examination Add?

A comprehensive examination may include:

Detailed medical and family history
Vision in each eye
Crowded visual acuity
Eye alignment
Eye movement
Stereoacuity
Pupil responses
Cycloplegic refraction
Slit-lamp examination
Dilated retinal examination
Additional tests when required

The AAO Pediatric Eye Evaluations Preferred Practice Pattern describes screening and comprehensive examination as related but distinct parts of paediatric eye care.

Why Can Screening Miss a Problem?

Possible reasons include:

The condition developed after screening.
The child guessed correctly.
The child used the better eye around an inadequate occluder.
Cooperation was limited.
The screening tool did not test that condition.
Hyperopia was hidden by accommodation.
Strabismus was intermittent.
The abnormality was outside the device’s referral criteria.
Follow-up did not occur after a failed result.

Systematic reviews show that preschool screening accuracy varies by test, age, setting and definition of disease.

What if the Child Passes Screening but Parents Remain Concerned?

Arrange a comprehensive assessment when there is persistent concern about:

Squinting
Head tilt
Closing one eye
Difficulty seeing the board
Reading fatigue
Headaches
Eye rubbing
Abnormal photographs
Poor depth judgement
An eye turn
Delayed visual behaviour

A screening result should not overrule a convincing symptom or visible abnormality.

What if the Child Fails a Screening?

Parents should:

Read the referral instructions
Arrange the recommended assessment
Bring the screening result
Bring current glasses
Avoid assuming that the child will grow out of it
Inform the clinic of any visible eye turn or white pupil

A failed screening does not always mean serious disease.

It does mean that the result should be confirmed.

What if the Child Was “Unable to Test”?

An untestable child may simply be:

Shy
Tired
Unfamiliar with the symbols
Developmentally unable to perform the test

However, poor vision may also make the test difficult.

The next step may be:

Repeat screening
Instrument-based screening
Comprehensive assessment
Objective refraction

The decision should reflect the child’s age and risk factors.

How Soon Should a Failed Screening Be Followed Up?

The urgency depends on the finding.

Prompt or Urgent Assessment

Arrange prompt assessment for:

White pupil
Abnormal red reflex
Constant strabismus
Sudden eye turn
Poor visual behaviour
New double vision
Eye pain
Eye trauma
Marked asymmetry
Suspected eye disease

Routine but Timely Assessment

A routine referral for reduced chart vision or a suspected refractive error should still be completed rather than delayed for many months.

The potential benefit of screening is lost when referred children do not receive examination and treatment. Updated screening recommendations therefore emphasise reliable referral and follow-up systems.

Why a Child May Need an Earlier Check Than Planned

New Blurred Vision

The child may report:

Difficulty seeing the board
Blurred television subtitles
Needing to sit closer
Difficulty recognising distant faces
One eye being blurrier

Squinting

Squinting temporarily narrows the opening through which light enters and may slightly improve focus.

It can be a sign of refractive error.

Closing One Eye

This may occur with:

Unequal vision
Strabismus
Double vision
Light sensitivity
Intermittent exotropia

Head Tilt or Face Turn

A persistent abnormal head posture may help the child compensate for:

Strabismus
Nystagmus
Ptosis
Unequal vision
Astigmatism
Restricted eye movement

Headaches During Visual Tasks

Possible causes include:

Uncorrected refractive error
Prolonged near work
Migraine
Dry eye
Binocular-vision difficulty
Poor ergonomics
Non-ocular medical conditions

An eye examination can identify or exclude important ocular causes but does not diagnose every cause of headache.

Eye Rubbing

Frequent rubbing may be associated with:

Allergy
Dryness
Fatigue
Habit
Corneal irritation
Keratoconus risk

Treating the cause of itch is more helpful than repeatedly instructing the child not to rub.

Reading or School Difficulties

Children with refractive error may struggle with:

Seeing the board
Reading small print
Sustaining visual attention
Copying
Hand-eye coordination

However, an eye examination does not diagnose dyslexia, language disorders or attention disorders.

Abnormal Photographs

Repeated:

White pupil
Unequal red reflex
One eye consistently turning
Unusual pupil appearance

should be assessed.

Eye Injury

Eye injuries may cause internal damage even when external redness is mild.

Prompt assessment is particularly important for:

Sharp trauma
High-speed projectiles
Chemical exposure
Reduced vision
Irregular pupil
Blood inside the eye
Persistent pain

Sudden Flashes or Floaters

These are uncommon in younger children but require prompt assessment, especially with:

High myopia
Eye trauma
Previous retinal surgery
A curtain or shadow
Sudden reduced vision

Eye Checks and Myopia Prevention

Does Regular Testing Prevent Myopia?

An eye examination does not prevent myopia by itself.

It allows earlier detection and timely discussion of:

Outdoor time
Near-work habits
Optical myopia control
Low-dose atropine
Contact-lens options
Axial-length monitoring

How Much Outdoor Time Is Helpful?

Research consistently associates greater outdoor exposure with a lower risk of developing myopia.

Outdoor time appears more effective in reducing myopia onset than in reversing or completely stopping established myopia.

Parents should build regular outdoor activity into the child’s routine while considering sun protection, hydration and heat safety.

Should Parents Check Vision at Home?

Parents can observe function but should not rely on home testing as a substitute for formal screening.

Useful observations include:

Covering each eye separately during a familiar task
Noticing whether one eye causes greater objection when covered
Watching whether the child sits closer than before
Asking whether each eye sees similarly
Looking for an eye turn in photographs and daily activities

Home observations cannot accurately measure:

Prescription
Amblyopia
Eye pressure
Retinal health
Optic-nerve health
Subtle strabismus

Common Myths

“Every Child Needs a Specialist Eye Examination Every Year”

Not necessarily.

Healthy children who pass reliable recurrent screening and have no symptoms or risk factors may not require annual specialist examinations.

“School Screening Means No Other Eye Checks Are Needed”

False.

Screening does not replace condition-specific follow-up or examination for new symptoms.

“My Child Will Tell Me When Their Vision Changes”

Not always.

Children may not recognise gradual or one-sided blur.

“One Normal Screening Result Protects My Child Until Adulthood”

False.

Myopia and other eye conditions can develop later.

“A Child with Good Grades Cannot Have an Eye Problem”

False.

Children often compensate effectively.

“One Good Eye Is Enough”

False.

The weaker eye may develop amblyopia, and binocular vision may be affected.

“Children Who Wear Glasses Must Be Checked Every Month”

Usually false.

The appropriate interval depends on age, diagnosis and treatment.

“Glasses Prescriptions Always Change Every Six Months”

False.

Some prescriptions remain stable.

Others change faster.

“Myopia-Control Treatment Means Ordinary Reviews Are No Longer Needed”

False.

Treatment requires monitoring of both effectiveness and safety.

“If the Child Passes a Photoscreener, Hyperopia Is Excluded”

False.

Instrument-based screening can underestimate or miss hyperopia, particularly without cycloplegia.

“If a Child Cannot Complete Screening, Their Vision Is Probably Normal”

False.

An untestable result may require rescreening or examination.

“Dilating Drops Are Needed at Every Visit”

False.

Their use depends on the purpose of the visit and previous findings.

“Eye Checks Are Only About Glasses”

False.

They may assess:

Alignment
Visual development
Pupils
Cornea
Lens
Retina
Optic nerve
Neurological function

Frequently Asked Questions

My Child Has Never Complained. Do They Still Need Screening?

Yes.

Amblyopia and one-sided refractive errors may produce no obvious complaint.

My Child Passed Screening Last Year. When Is the Next Check?

For a child aged five or older with no symptoms or risk factors, repeat screening within approximately one to two years is reasonable.

Follow the local school, primary-care or eye-care schedule.

Should My Child Have an Eye Test Before Starting School?

A reliable preschool visual assessment is valuable because it may detect reduced vision before formal classroom demands increase.

Should Children Be Checked Before They Can Read?

Yes.

Babies and preschool children can be assessed without letters.

Does My Child Need an Eye Test Every Time the Glasses Break?

Not automatically.

If the prescription is recent and vision has not changed, replacement may be possible using existing details.

An examination is sensible when:

The scheduled review is due
The prescription is old
Symptoms have changed
The child has amblyopia or progressive myopia

How Often Should Glasses Be Changed?

Glasses should be changed when:

The prescription changes meaningfully
The lenses are damaged
The frame no longer fits
The optical centres are poorly positioned
The child’s visual needs change

A new pair is not automatically required at every appointment.

Can My Child Be Checked While Wearing Contact Lenses?

The child should bring:

Contact lenses
Lens packaging
Glasses
Cleaning products

The lenses may need to be removed to examine the cornea or measure refraction.

How Often Should Axial Length Be Measured?

During active myopia management, approximately six-monthly measurement is commonly recommended when axial-length technology is available.

The result should be interpreted with refraction, age and treatment history.

My Child’s Myopia Has Not Changed in Six Months. Can Follow-Up Stop?

Usually not immediately.

One stable interval does not prove that future progression has ended.

Longer-term stability should be demonstrated.

Why Has the Doctor Asked for Review in Six Weeks?

Short-interval review may be needed to assess:

Amblyopia response
New glasses
Patching
Atropine
Eye alignment
Healing after surgery
An uncertain finding

Why Has the Doctor Asked for Review Only in One Year?

A longer interval may be appropriate when:

Vision is equal and stable
The prescription is stable
Eye alignment is normal
No active treatment is required
The eyes are otherwise healthy

Should Siblings Be Checked?

Siblings should undergo routine age-appropriate screening.

Earlier comprehensive examination may be appropriate when there is a strong family history of:

Amblyopia
Strabismus
High refractive error
Keratoconus
Inherited eye disease

My Child Failed Screening but Sees Small Objects. Is an Examination Necessary?

Yes.

The child may be using one better-seeing eye.

Seeing small near objects does not prove that both eyes have normal distance vision.

Can a Child’s Vision Change Between School Screenings?

Yes.

Myopia may progress over months.

Parents should arrange assessment when new symptoms develop.

Is a Vision Check Needed Before Contact Lenses?

Yes.

The child requires:

Accurate refraction
Corneal assessment
Lens fitting
Hygiene education
Follow-up

Do Children with Colour-Vision Deficiency Need Annual Eye Tests?

Congenital colour-vision deficiency is usually stable and does not by itself require annual specialist review.

Routine screening and eye care should continue.

Acquired colour-vision change may indicate retinal or optic-nerve disease and requires assessment.

Does Frequent Eye Testing Harm a Child?

No.

Routine vision assessment, refraction and non-invasive imaging do not weaken or damage the eyes.

Dilating drops and specialised tests are used when clinically appropriate.

When to Seek Urgent Eye Care

Do not wait for the next scheduled examination when a child develops:

A white pupil
Sudden loss of vision
A sudden eye turn
New double vision
Severe eye pain
Significant redness with reduced vision
Marked light sensitivity
A cloudy cornea
Eye trauma
Chemical exposure
New abnormal eye movements
A severe headache with vomiting or neurological symptoms
New flashes, floaters or a curtain in the vision
A painful red eye while wearing contact lenses

These symptoms may indicate:

Retinal disease
Cataract
Glaucoma
Infection
Eye injury
Optic-nerve disease
Neurological disease
Another ocular emergency

A Parent’s Eye-Check Schedule

Birth to One Year

Attend routine newborn and infant assessments.
Seek earlier examination for an abnormal reflex, poor tracking, persistent eye turn or structural concern.

One to Three Years

Complete age-appropriate screening during routine healthcare or preschool programmes.
Attend comprehensive examination after a failed or untestable screen.

Three to Five Years

Ensure that each eye has been tested separately using visual acuity or an appropriate screening device.
Do not delay follow-up after an abnormal result.

Five Years and Older

Continue vision screening every one to two years.
Arrange earlier assessment for new symptoms or risk factors.

Children Wearing Glasses

Follow the prescribed interval, commonly every six to twelve months.
Younger children and those receiving amblyopia treatment may require earlier review.

Children with Myopia

Review approximately every six months during progression or myopia-control treatment.
Monitor axial length when available.

Children with Amblyopia or Strabismus

Attend reviews over weeks or months as advised.
Do not rely on school screening to monitor treatment.

Children Wearing Contact Lenses

Attend fitting and aftercare appointments.
Seek prompt assessment for pain, redness, light sensitivity or sudden blur.

Questions to Ask the Eye-Care Professional

Is my child’s vision equal in both eyes?
Did my child pass an age-appropriate test?
Was the result reliable?
Is a cycloplegic refraction required?
Does my child have amblyopia?
Are the eyes properly aligned?
Does my child need glasses?
How often should the glasses be worn?
Is my child myopic?
Is the myopia progressing?
Should axial length be monitored?
Is myopia-control treatment appropriate?
When should the next examination occur?
What changes should prompt an earlier visit?
Can school screening monitor this condition?
Do siblings require earlier assessment?
Are contact lenses appropriate?
Are protective glasses needed for sports?

The Bottom Line

Children should receive age-appropriate vision and eye screening from infancy through the school years.

A practical schedule is:

Visual assessment during newborn and infant care
Screening during the toddler years
Reliable monocular screening during the preschool years
Repeat screening every one to two years from age five onward

A healthy, symptom-free child who repeatedly passes reliable screening does not necessarily need a comprehensive specialist eye examination every year.

A comprehensive examination is appropriate when:

Screening is failed
Screening cannot be completed
Symptoms are present
Risk factors are present
A parent or teacher remains concerned
An eye condition has already been diagnosed

More frequent follow-up may be needed for:

Glasses
Progressive myopia
Myopia-control treatment
Amblyopia
Strabismus
Contact lenses
Prematurity
Developmental conditions
Diabetes
Steroid use
Previous eye surgery

Children with progressive myopia are commonly reviewed approximately every six months.

Children receiving amblyopia treatment may need review after several weeks.

Children with stable glasses may be reviewed every six to twelve months.

The next appointment should always be brought forward when a new visual symptom or visible abnormality develops.

The most important message is:

Eye-check frequency should be based on the child’s age and risk—not simply the calendar. Routine screening is valuable, but parents should never wait for the next school or annual check when vision changes, an eye turns, a pupil looks white or another concerning symptom appears.
