More children are developing myopia across the world.
They may struggle to see the classroom board. They may also squint at road signs or move closer to the television.
This increase is often described as the childhood myopia epidemic.
However, myopia is not caused by one habit alone. Genetics, age, outdoor exposure and close visual work may all contribute.
Therefore, parents should not blame themselves or their children.
Instead, families can focus on early detection, healthy visual habits and suitable professional care.
What Is Childhood Myopia?
Myopia is also called short-sightedness.
A child with myopia usually sees close objects more clearly than distant objects. For example, they may read a book easily but struggle to see the classroom board.
In many myopic eyes, light focuses in front of the retina rather than directly on it.
This often happens because the eye has grown longer from front to back. However, the shape of the cornea and the natural lens inside the eye can also affect the prescription.
Myopia commonly begins during the school years. It may then continue to change as the child grows.
You can read more about the condition on Eye Philosophy’s myopia information and management page.
How Common Is the Childhood Myopia Epidemic?
Research shows that myopia has become more common across many regions.
A widely cited global study estimated that almost five billion people may have myopia by 2050. This would represent close to half of the world’s population. However, this projection covers people of all ages and remains an estimate rather than a certain outcome. Read the global myopia prevalence study.
More recent research has focused specifically on children and teenagers.
A 2025 analysis reviewed 276 studies involving more than 5.4 million participants from 50 countries. It estimated that childhood and adolescent myopia prevalence rose from about 24% in 1990 to almost 36% in 2023. The researchers projected that it may reach approximately 40% by 2050. Read the childhood myopia prevalence study.
These figures do not mean every country or community will experience the same rate.
Myopia prevalence can vary according to:
- Age
- Genetics
- Ethnic background
- Education systems
- Urban or rural living
- Outdoor exposure
- Near-work habits
- Access to eye care
Therefore, global statistics should guide awareness rather than predict an individual child’s future.
Why Is Childhood Myopia Increasing?
There is no single cause behind the childhood myopia epidemic.
Researchers believe myopia develops through a mix of genetic and environmental factors.
Family History
A child may have a higher chance of developing myopia when one or both parents are myopic.
However, family history does not guarantee that the child will become short-sighted.
Likewise, children without myopic parents can still develop the condition.
Younger Age at Onset
Children who develop myopia at a younger age may have more years for the condition to progress.
The International Myopia Institute identifies younger age at onset as an important factor linked with faster progression. Read the International Myopia Institute clinical guidelines.
Therefore, early detection can provide more time to monitor change and discuss suitable management options.
Less Time Outdoors
Children who develop myopia often spend less time outdoors than children who remain non-myopic.
Outdoor exposure may involve several helpful factors. These include brighter natural light, looking across longer distances and taking breaks from close work.
However, outdoor time should not be described as a cure.
Evidence suggests that spending more time outdoors may help reduce the chance of myopia developing. Its effect on slowing progression after myopia has already started is less certain.
The International Myopia Institute recommends encouraging sufficient outdoor activity alongside appropriate reading distances and regular breaks from close work.
Long Periods of Close Work
Reading, homework, drawing and screen use all involve near vision.
Near work is a normal part of childhood. Therefore, children do not need to avoid books or education.
However, very close reading distances and long periods without breaks may be linked with a higher risk of myopia development and progression.
The International Myopia Institute notes an association with reading closer than 20 centimetres and continuous near work lasting longer than 45 minutes.
This does not mean that one long homework session causes myopia. Instead, repeated habits may form part of the wider risk picture.
Modern Indoor Lifestyles
Many children now move between classrooms, homework, gaming and streaming.
As a result, they may spend less time looking into the distance.
Urban families may also have less easy access to outdoor spaces. Busy schedules, weather and safety concerns can create further limits.
The solution should remain realistic.
Parents do not need to remove every device. Instead, they can create a healthier balance between close work, rest and outdoor activity.
Does Screen Time Cause Childhood Myopia?
Screen use is often blamed for the childhood myopia epidemic.
However, the relationship is more complex.
Screens usually involve close viewing. They can also replace outdoor activities. In addition, children may use devices for long periods without changing focus.
These habits may contribute to the visual environment linked with myopia.
Still, researchers cannot say that screens alone cause every case.
A child may use screens often and never develop myopia. Another child may develop myopia despite limited device use.
Therefore, parents should avoid fear-based rules.
A more practical approach includes:
- Keeping screens at a suitable distance
- Using devices in a well-lit room
- Encouraging regular breaks
- Avoiding very long sessions without rest
- Balancing device use with outdoor activity
- Arranging eye tests when concerns arise
What Are the Early Signs of Childhood Myopia?
Children do not always complain about blurry vision.
They may assume that everyone sees the same way.
Parents and teachers may notice:
- Squinting at distant objects
- Moving closer to the television
- Asking to sit near the classroom board
- Difficulty recognising people from a distance
- Holding devices close to the face
- Copying classroom notes slowly
- Losing interest in distance-based activities
- Complaining that road signs look blurry
- Struggling to follow a ball during sport
- Frequent blinking or eye rubbing
- Headaches after school
- A drop in classroom confidence
These signs do not prove that a child has myopia.
Other vision, learning or health concerns may cause similar behaviour.
A comprehensive children’s eye examination can help identify whether vision is involved.
Eye Philosophy provides children’s eye tests and myopia management in Melbourne at its Williamstown and Doncaster clinics. The clinic’s children’s eye-care information notes that children may not realise their vision differs from normal.
Why Does Early Myopia Onset Matter?
Myopia may continue changing throughout childhood.
Therefore, a child who becomes myopic at age seven may have more years of potential progression than a teenager who develops it later.
This does not mean that every younger child will develop high myopia.
However, age can help the optometrist assess risk and decide how closely the child should be monitored.
The practitioner may consider:
- The child’s age
- Current prescription
- Previous prescription changes
- Axial length
- Family history
- Eye health
- Outdoor time
- Near-work habits
- Existing treatment
- Ability to follow a care routine
A single factor should not determine the plan.
Instead, the optometrist should review the full picture.
Why Is High Myopia a Concern?
Higher levels of myopia are associated with an increased lifetime risk of several eye conditions.
These may include:
- Retinal tears
- Retinal detachment
- Myopic macular changes
- Glaucoma
- Cataracts
However, this does not mean that every myopic child will develop one of these conditions.
Most children with myopia do not have these complications.
The purpose of myopia management is not to frighten families. Instead, it aims to slow progression where possible and support long-term monitoring.
No treatment can remove every future risk.
Are Standard Glasses Enough?
Standard single-vision glasses correct blurry vision.
They remain important because children need clear vision for learning, sport and daily activities.
However, standard single-vision glasses are not specifically designed to slow myopia progression.
Modern myopia management may involve optical or prescription treatments that aim to influence how the eye grows.
Possible options include:
- Specialised myopia management spectacle lenses
- Dual-focus soft contact lenses
- Orthokeratology lenses
- Prescription atropine eye drops
- Combined approaches in selected cases
- Lifestyle guidance
- Regular clinical monitoring
No option suits every child.
Each treatment has possible benefits, limitations, costs and risks. Therefore, an optometrist must assess the child before making a recommendation.
Can Childhood Myopia Be Cured?
Currently, there is no established cure that permanently removes childhood myopia.
Glasses and contact lenses can correct blurry vision while they are used.
Ortho-K temporarily changes the shape of the cornea to provide clearer daytime vision. However, the effect is reversible and requires ongoing lens wear.
Myopia management aims to slow progression. It cannot promise that the prescription or axial length will stop changing.
Families should be cautious of claims that a product can:
- Cure myopia permanently
- Reverse all eye growth
- Guarantee stable vision
- Prevent every future eye problem
- Work equally well for every child
Treatment outcomes vary.
What Can Melbourne Parents Do Now?
The global rise in myopia may feel overwhelming.
However, parents can take practical steps without creating anxiety.
Arrange Regular Children’s Eye Tests
Do not wait for a child to complain.
Eye tests can assess:
- Distance and near vision
- The glasses prescription
- Eye coordination
- Focusing ability
- General eye health
- Myopia risk factors
- Changes from earlier visits
The review schedule should depend on the child’s age, findings and treatment plan.
Encourage Outdoor Activity
Outdoor time supports general health and may help reduce the chance of myopia developing.
Choose activities your child enjoys.
For example:
- Walking
- Cycling
- Playground visits
- Outdoor sport
- Gardening
- Family picnics
- Playing at the beach
- Walking the dog
Outdoor time does not need to involve intense exercise.
Children should still use suitable sun protection. This may include a hat, shade and sunglasses with appropriate UV protection.
Improve Near-Work Habits
Encourage a comfortable reading distance.
Children should avoid holding books or screens extremely close for long periods.
They can also:
- Change focus regularly
- Take short movement breaks
- Sit with good posture
- Use adequate lighting
- Increase text size when needed
- Avoid reading in awkward positions
- Use a suitable desk and chair
Watch for Behavioural Changes
Ask teachers whether the child struggles with distance tasks.
Also, ask the child simple questions.
For example:
- Can you see the classroom board clearly?
- Do road signs look blurry?
- Do you move closer to see the television?
- Do your eyes feel tired after school?
- Is one eye clearer than the other?
Avoid leading the child toward a particular answer.
Keep Previous Prescriptions
Old prescriptions help the optometrist assess how quickly vision has changed.
Bring earlier glasses, reports and treatment records to the appointment.
Follow the Recommended Review Schedule
A child may still see clearly through their current glasses while their prescription changes.
Therefore, do not rely only on symptoms.
Children receiving myopia management may need more frequent reviews than children attending routine eye examinations.
What Happens During a Myopia Assessment?
A myopia assessment usually begins with a detailed history.
The optometrist may ask about:
- Family history
- Age when blur began
- Previous prescriptions
- School performance
- Outdoor activity
- Reading distance
- Screen habits
- Sport
- Current glasses or contact lenses
- Health conditions
- Medicines
Testing may include:
- Visual acuity
- Refraction
- Eye coordination
- Focusing assessment
- Eye health examination
- Corneal measurements
- Axial length measurement
- Retinal imaging when clinically indicated
Not every child requires every test.
The practitioner should explain why additional measurements are being recommended.
Parents can also review Eye Philosophy’s information about comprehensive eye examinations in Melbourne before the appointment.
How Is Myopia Progression Monitored?
Monitoring should involve more than asking whether the child can see clearly.
The optometrist may compare:
- Current and previous prescriptions
- Axial length measurements
- Unaided and corrected vision
- Eye health findings
- Treatment use
- Comfort
- Lens fit
- Changes in daily activities
The goal is to identify patterns over time.
One result does not always show whether a treatment is helping. In addition, normal measurement variation can occur.
Therefore, the practitioner should assess repeated findings rather than treating one number as a pass-or-fail result.
Questions Parents Can Ask the Optometrist
Parents should understand why a treatment or test is being recommended.
Consider asking:
- Does my child currently have myopia?
- How quickly has the prescription changed?
- Is axial length being monitored?
- What risk factors apply to my child?
- Which management options may be suitable?
- What are the possible risks?
- What can we realistically expect?
- How often will reviews occur?
- How will we know whether the plan is helping?
- What happens if progression continues?
- Will my child need backup glasses?
- What are the initial and ongoing costs?
An informed discussion can help families choose a practical plan.

Final Thoughts on the Childhood Myopia Epidemic
Childhood myopia is becoming more common worldwide.
However, global projections do not determine what will happen to one child.
Parents can focus on actions that remain within their control.
Encourage outdoor activity. Improve close-work habits. Watch for signs of blurry distance vision. Most importantly, arrange a comprehensive eye examination when concerns arise.
When myopia is confirmed, ask about the child’s rate of change and available management options.
Early assessment cannot guarantee that progression will stop. However, it can provide a clearer starting point for monitoring and informed care.
The next article explains the available ways to slow short-sightedness after myopia has been identified. These topics are connected because understanding the global rise creates awareness, while the related article focuses on practical management options.
