Myopia in Children

Myopia in children, also called short-sightedness, causes blurred distance vision. Your child may see clearly up close, but struggle to see the board at school, road signs, sport, subtitles, or faces across a room.

At Innovative Eye Care, we provide children’s myopia assessments at our Adelaide and Henley Beach practices. We check your child’s vision, prescription, eye health, visual development, and eye growth to understand whether myopia is present and whether it is changing.

What is Myopia in Children?

Myopia occurs when the eye focuses light in front of the retina instead of directly on it. In many children, this happens because the eye grows too long from front to back.1

A child with myopia can usually see well up close, but distance vision is blurred. This can affect school, sport, confidence, and day-to-day tasks.

The Rise of Myopia in Children

Myopia is becoming more common in children around the world. Global modelling suggests that almost half of the world’s population may be myopic by 2050.2

‍

This rise is thought to be linked to a mix of genetics, education demands, near work, reduced outdoor time, and lifestyle changes.1,3

‍

Children are also developing myopia at younger ages. This matters because younger children have more years of eye growth ahead of them. The earlier myopia starts, the more time it has to progress.2

Why Childhood Myopia Matters

Myopia is more than needing glasses.

‍

Low levels of myopia can cause blurry distance vision. Higher levels of myopia are linked with increased lifetime risk of eye disease, including myopic macular degeneration, retinal detachment, glaucoma, and cataract.4

‍

This does not mean every child with myopia will develop eye disease. It means early detection and regular monitoring are important.

‍

The aim is to:

  • Detect myopia early
  • Understand whether it is progressing
  • Monitor how the eye is growing
  • Keep vision clear for school and daily life
  • Identify whether myopia control should be considered

What Causes Myopia in Children?

Myopia usually develops from a mix of inherited and lifestyle factors.

‍

Your child may have a higher risk if:

  • One or both parents are short-sighted
  • They spend long periods reading or using screens
  • They hold books or devices very close
  • They spend limited time outdoors
  • Their prescription is changing quickly
  • They developed myopia at a young age

‍

Research suggests that more outdoor time can reduce the risk of children developing myopia.5,6 Once myopia has already started, outdoor time is still helpful, but regular monitoring is needed.

Signs Your Child May Be Short-Sighted

Children do not always complain about blurry vision. Many assume their vision is normal.

Common signs include:

  • Squinting to see far away
  • Difficulty seeing the board at school
  • Moving closer to the TV
  • Holding books, tablets, or phones close
  • Complaining of headaches or tired eyes
  • Reduced confidence with ball sports
  • Avoiding distance tasks
  • Losing place while copying from the board
  • Needing frequent glasses prescription changes

‍

Sometimes the signs are subtle. A child may still read well, perform well at school, and only struggle with distance tasks.

When Should a Child Have an Eye Test?

We recommend an eye test if your child:

  • Complains of blurred distance vision
  • Squints or sits close to screens
  • Has trouble seeing the board
  • Has headaches or tired eyes
  • Has one or both parents with myopia
  • Has had a recent prescription change
  • Holds reading material very close
  • Avoids sport or distance-based activities
  • Has not had a full eye examination before starting school

A school vision screening can be useful, but it is not the same as a comprehensive children’s eye examination. A full assessment looks at vision, focusing, eye teaming, prescription, eye health, and eye growth.

How We Test for Myopia in Children

At Innovative Eye Care, we make children’s eye tests calm, clear, and age appropriate. The examination is adjusted to your child’s age, attention, confidence, and symptoms.

A children’s myopia assessment may include:

Distance vision testing

We check how clearly your child can see letters, pictures, or symbols at a distance. This helps identify whether their distance vision is reduced and whether myopia may be present.

Near vision testing

We assess how your child sees up close. Children with myopia often see well at near, but near testing still helps us understand overall visual function.

Prescription assessment

We measure whether your child needs glasses and how much correction is required. This may involve asking your child which lenses look clearer, as well as using instruments that estimate the prescription objectively.

In some children, eye drops may be recommended to relax the focusing system and give a more accurate prescription. This is called cycloplegic refraction and can be useful when the focusing system is very active.1

Eye focusing assessment

Children use their focusing system heavily for reading, schoolwork, and screens. We assess whether the eyes can focus accurately and comfortably.

Eye teaming assessment

We check how well the two eyes work together. Eye teaming problems can cause eyestrain, headaches, double vision, reading discomfort, or reduced confidence with near tasks.

Eye movement assessment

We assess how accurately the eyes move and track. This can be relevant for reading, copying from the board, sport, and classroom tasks.

Eye health assessment

We examine the front and back of the eyes to check ocular health. This helps rule out other causes of blurred vision and provides a baseline for future care.

Axial length measurement

Axial length measures the length of the eye from front to back. This is important in childhood myopia because progression is closely linked with eye growth.1

Measuring axial length helps us monitor whether your child’s eyes are growing faster than expected, even before large prescription changes are noticed.

Corneal shape assessment

In some children, we may measure the shape of the front surface of the eye. This can be useful if vision is changing quickly, astigmatism is present, contact lenses are being considered, or we need to rule out other causes of blur.

Lifestyle and family history review

We ask about your child’s school demands, screen use, reading habits, outdoor time, sport, hobbies, and family history of myopia. These details help us understand your child’s risk profile.

What Happens After The Test?

After the examination, we explain the results in clear language.

We will discuss:

  • Whether your child has myopia
  • How strong the prescription is
  • Whether glasses are needed
  • Whether the eyes are growing as expected
  • Whether myopia appears stable or progressive
  • Whether myopia control should be considered
  • When your child should be reviewed

If your child has myopia, we may recommend monitoring every 3 to 6 months. Some children need closer review, especially if they are younger, progressing quickly, or starting treatment.

How Parents Can Help at Home

You can support your child’s vision by encouraging healthy visual habits.

Helpful steps include:

  • Encourage regular outdoor time
  • Break up long periods of reading and screen use
  • Keep books and devices at a comfortable distance
  • Avoid reading or screen use very close to the face
  • Make sure your child wears their glasses as recommended
  • Book regular eye examinations
  • Ask your child whether the board at school looks clear

Outdoor time can help reduce the risk of developing myopia, but it does not replace an eye test or treatment advice if myopia is already progressing.5,6

When Myopia Control May Be Discussed

If your child has myopia, especially if it is progressing, we may discuss myopia control.

Myopia control aims to slow the rate of prescription change and eye growth. Options may include specialised myopia control spectacle lenses, orthokeratology, myopia control contact lenses, or low-dose atropine eye drops.1

This page is focused on children’s myopia assessment. You can learn more about treatment options here:

Frequently Asked Questions

Is myopia the same as short-sightedness?
Yes. Myopia and short-sightedness mean the same thing. A child with myopia usually sees close objects clearly but distant objects look blurry.
Can children grow out of myopia?
Children usually do not grow out of true myopia. It often progresses through childhood and the teenage years while the eye is still growing.1
How do I know if my child has myopia?
Common signs include squinting, blurry distance vision, sitting close to screens, difficulty seeing the board, and frequent prescription changes. A full children’s eye test is needed to confirm whether myopia is present.
Does screen time cause myopia?
Screen time alone is not the only cause. Myopia is linked to a mix of genetics, near work, reduced outdoor time, and lifestyle factors.1,3 Long periods of close work without breaks may increase risk.
Does outdoor time help?
Yes. Research suggests that more outdoor time can reduce the risk of children developing myopia.5,6 Children with existing myopia still need regular eye examinations.
How often should children with myopia be reviewed?
Many children with myopia are reviewed every 3 to 6 months. The timing depends on age, prescription, eye growth, symptoms, and whether myopia is progressing.
